Various fixes. Added CanSeeProduct functionality back in but also left in old style product groups. Removed references to usebuggroupsentry and usebuggroups since we want it on all the time.

-# Build a mozilla application.
-#
-# To checkout and build a tree,
-#    1. cvs co mozilla/client.mk
-#    2. cd mozilla
-#    3. create your .mozconfig file with
-#       mk_add_options MOZ_CO_PROJECT=suite,browser,mail,xulrunner
-#    4. gmake -f client.mk 
-#
-# This script will pick up the CVSROOT from the CVS/Root file. If you wish
-# to use a different CVSROOT, you must set CVSROOT in your environment:
-#
-#   export CVSROOT=:pserver:anonymous@cvs-mirror.mozilla.org:/cvsroot
-#   export CVSROOT=:pserver:username%somedomain.org@cvs.mozilla.org:/cvsroot
-# 
-# You must specify which products/modules you wish to checkout, with
-#   MOZ_CO_PROJECT, MOZ_CO_MODULE, and BUILD_MODULES variables.
-#
-#   MOZ_CO_PROJECT possibilities include the following:
-#     suite (Seamonkey suite)
-#     browser (aka Firefox)
-#     mail (aka Thunderbird)
-#     composer (standalone composer, aka NVU)
-#     calendar (aka Sunbird, use this to build the calendar extensions also)
-#     xulrunner
-#     macbrowser (aka Camino)
-#
-# Other common MOZ_CO_MODULE options include the following:
-#   mozilla/other-licenses/libart_lgpl
-#   mozilla/tools/codesighs
-#
-# Other targets (gmake -f client.mk [targets...]),
-#    checkout
-#    build
-#    clean (realclean is now the same as clean)
-#    distclean
-#
-# See http://www.mozilla.org/build/ for more information.
-#
-# Options:
-#   MOZ_OBJDIR           - Destination object directory
-#   MOZ_CO_DATE          - Date tag to use for checkout (default: none)
-#   MOZ_CO_MODULE        - Module to checkout
-#   MOZ_CVS_FLAGS        - Flags to pass cvs (default: -q -z3)
-#   MOZ_CO_FLAGS         - Flags to pass after 'cvs co' (default: -P)
-#   MOZ_MAKE_FLAGS       - Flags to pass to $(MAKE)
-#   MOZ_CO_LOCALES       - localizations to pull (MOZ_CO_LOCALES="de-DE,pt-BR")
-#   MOZ_LOCALE_DIRS      - directories which contain localizations
-#   LOCALES_CVSROOT      - CVSROOT to use to pull localizations

- * What we do now:

- * HTML buffer, a transferable, an nsISupportsString and
- * a huge mess every time.  This is basically what nsPresShell::DoCopy does
- * to move the selection into the clipboard for Edit->Copy.
- * 
- * What we should do, to make our end of the deal faster:
- * Create a singleton transferable with our own magic converter.  When selection
- * changes (use a quick cache to detect ``real'' changes), we put the new
- * nsISelection in the transferable.  Our magic converter will take care of
- * transferable->whatever-other-format when the time comes to actually
- * hand over the clipboard contents.
- *
- * Other issues:
- * - which X clipboard should we populate?
- * - should we use a different one than Edit->Copy, so that inadvertant
- *   selections (or simple clicks, which currently cause a selection
- *   notification, regardless of if they're in the document which currently has
- *   selection!) don't lose the contents of the ``application''?  Or should we
- *   just put some intelligence in the ``is this a real selection?'' code to
- *   protect our selection against clicks in other documents that don't create
- *   selections?
- * - maybe we should just never clear the X clipboard?  That would make this 
- *   problem just go away, which is very tempting.

-<h2>Overview</h2>
-<p>
-  The Space Manager and related classes and structures are an important of
- the Gecko Layout system, specifically Block Layout. &nbsp;See the High Level
- Design document for an overview of the Space Manager, and as an introduction
- to the classes, structures and algorithms container in this, the Detailed

-<h2>nsSpaceManager</h2>
-<p>
-   The Space Manger is the central class is a group of classes that manage
- the occupied and available space that exists in horizontal bands across
-a  canvas. &nbsp;The primary goal of the Space Manager is to provide information
- about those bands of space to support the CSS notion of floated elements.
-</p>
- 
-<p>
-  There are three important parts to the Space Manger API: the parts that 
-deal with the coordinate space of the Space Manager, the parts that deal with
-the regions managed by the Space Manager, and the parts that manage float
-impact intervals.
-</p>
- 
-<p>
-  The class nsSpaceManager is declared in the file <a href="http://lxr.mozilla.org/seamonkey/source/layout/base/src/nsSpaceManager.h">
-  nsSpaceManger.h</a>
-  . &nbsp;The class is only used in the layout module and cannot be exported
- outside of that module (nor does it need to be). &nbsp;It is not a general
- purpose class, and is not intended to be subclasses<font color="#cc0000">

-<h4>Life Cycle:</h4>
-<p>
-  The Constructor requires a Presentation Shell, used for arena allocations
- mostly, and a frame that this Space Manager is rooted on. &nbsp;The coordinate
- space of this Space Manger is relative to the frame passed in to the constructor.

-<p>
-  Operators 'new' and 'delete' are overridden to support a recycler. &nbsp;Space
- Manager instances come and go pretty frequently, and this recycler prevents
- excessive heap allocations and the performance penalties associated with
-it. The #define NS_SPACE_MANAGER_CACHE_SIZE is used to control the number
-of Space Manager instances that can be present in the recycler, currently
-4. &nbsp;If more than NS_SPACE_MANAGER_CACHE_SIZE are allocated at a time,
-then standard allocation is used.

- A Static method is used to shutdown the Space Manager recycling. &nbsp;This 
-method deletes all of the Space Mangers inthe recycler,and prevents further 
-recycling. &nbsp;It is meant to be called only when the layout module is being

-<h3>Implementation Notes</h3>
- 
-<h4></h4>
- 
-<h4>Algorithm 1: GetBandData</h4>
-<p>
-GetBandData is used to provide information to clients about what space if
-available and unavailable in a band of space. &nbsp;The client provides a
-vertical offset, the yOffset, that corresponds to the band that is of interest.
-&nbsp;This will be the y offset of the frame that is being reflowed. &nbsp;The
-caller also provides a collection of BandData objects (an array) and the
-number of items that the collection can handle. &nbsp;If the collection is
-too small, then an error is returned and the count is updated to indicate
-the size required.
-</p>
-
-<p>
-The algorithm to provide the band data is as follows:
-</p>
-<ul>
-  <li>Get a &nbsp;vertical offset in world coordinates (instead of frame-relative
-coordinates) by adding the y-origin of the SpaceManager to the y offset passed
-in</li>
-  <li>If the (adjusted) y value passed in is greater than the greatest band
-being managed, then all space is available so a single trapezoid is returned,
-marked as available and sized to the maximum size value (passed in).</li>
-  <li>If the (adjusted) y offset intersects a band, then gather the band
-data:</li>
-  <ul>
-    <li>walk the internal bandData list from head to tail</li>
-    <li>for each band data entry, see if the top of the band is greater than
-the (adjusted) y offset requested</li>
-    <li>if it is, then band is below the offset requested, so the area between
-the band and the y offset is available - create a trapezoid with that region
-and return it.</li>
-    <li>if the (adjusted) y offset is between the band top and bottom, then
-get the available space for the band by calling GetBandAvailableSpace</li>
-    <li>otherwise, move to the next band</li>
-  </ul>
-</ul>
-<h5>GetBandAvailableSpace:</h5>
-This method is called from GetBandData only. It walks all of the bands in
-the space manager and determines which bands intersect with the band passed
-in, and if within those bands there are regions that are available or occupied.
-
-<ul>
-  <li>First, walk all of the bands until a band that is to the right of the
-desired offset is located</li>
-  <li>Starting at that band, &nbsp;walk the remaining bands:</li>
-  <ul>
-    <li>if the current band is to the right of the requested band, then there
-is available space.&nbsp;</li>
-    <ul>
-      <li>if there is more room in the bandData collection, then add a trapezoid
-to the bandData collection such that it is marked as available and has a
-rect that represents the space between the reference band tna dht band being
-examined</li>
-      <li>if there is no more room in the BandData collection, estimate the
-number of entries requires as the current count + twice the number of bands
-below the reference band, plus two. &nbsp;Return an error code so the caller
-can reallocate the collection and try again.</li>
-    </ul>
-    <li>check the size of the collection again, if there is no room left
-then estimate the number of items requires as the current count + twice the
-number of bands below the band in question plus one.&nbsp;</li>
-    <li>create a new trapezoid in the band collection that has a region corresponding
-to the reference band rect, marked as occupied by either a single or multiple
-frames.</li>
-    <li>move to the next band</li>
-  </ul>
-  <li>after walking all of the band data, se if we have reached the right
-edge of the band.&nbsp;</li>
-  <ul>
-    <li>If not, then check for space in the band collection</li>
-    <ul>
-      <li>if there is no room left, then set the count to the current count
-plus 1 and return an error.</li>
-      <li>otherwise, create another entry in the band collection, marked
-as available, and with a rect corresponding to the area remainin in the band
-(eg. from the right edge of the last band rect to the right edge of the band).</li>
-    </ul>
-  </ul>
-</ul>
- 
-<h4>Algorithm 2: AddRectRegion</h4>
-Clients call into this method to notify the Space Manger that a new frame
-is occupying some space.
-
-<ul>
-  <li>First, try to get frame info for the frame. If it is found, return
-an error since the frame is already associated with a region in the Space
-Manager.</li>
-  <li>Next, create a rect from the occupied space passed in by the caller,
-transforming it first to world-coordinates by adding the Space Manager's
-offset to the occupied space rect passed in.</li>
-  <li>Create a new Frame Info instance for the frame and rect, returning
-an error if allocation fails.</li>
-  <li>Check if the occupied space rect (adjusted) is empty, if so, return
-an error &nbsp;(<font color="#cc0000">NOTE: this could be done earlier, or
-prevented by the caller</font>)</li>
-  <li>Allocate a new BandRect instance with the rect and frame as constructor
-arguments, and insert it into the collection via InsertBandRect</li>
-</ul>
-<h5>InsertBandRect:</h5>
-Internal method to insert a band rect into the BandList in the correct location.
-There are several cases it has to handle, as specified in the source file
-comments:
-
-<pre>// When comparing a rect to a band there are seven cases to consider.
-// 'R' is the rect and 'B' is the band.
-//
-//      Case 1              Case 2              Case 3              Case 4
-//      ------              ------              ------              ------
-// +-----+             +-----+                      +-----+             +-----+
-// |  R  |             |  R  |  +-----+    +-----+  |     |             |     |
-// +-----+             +-----+  |     |    |  R  |  |  B  |             |  B  |
-//          +-----+             |  B  |    +-----+  |     |    +-----+  |     |
-//          |     |             |     |             +-----+    |  R  |  +-----+
-//          |  B  |             +-----+                        +-----+
-//          |     |
-//          +-----+
-//
-//
-//
-//      Case 5              Case 6              Case 7
-//      ------              ------              ------
-//          +-----+    +-----+  +-----+    +-----+
-//          |     |    |  R  |  |  B  |    |     |  +-----+
-//          |  B  |    +-----+  +-----+    |  R  |  |  B  |
-//          |     |                        |     |  +-----+
-//          +-----+                        +-----+
-// +-----+
-// |  R  |
-// +-----+
-//
-</pre>
-<ul>
-  <li>First, check for the easiest case, where there are no existing band
-rects, or the band rect passed in is below the bottommost rect. In this case,
-just append the band rect and return.</li>
-  <li>Starting at the head of the list of bandRects, check for intersection
-with the rect passed in:</li>
-  <ul>
-    <li>case #1: the rect is totally above the current band rect, so insert
-a new band rect before the current bandRect</li>
-    <li>cases #2 and #7: the rect is partially above the band rect, so it
-is divided into two bandRects, one entirely above the band, and one containing
-the remainder of the rect. &nbsp;Insert the part that is totally above the
-bandRect before the current bandRect, as in case #1 above, and adjust the
-other band rect to exclude the part already added.</li>
-    <li>case #5: the rect is totally below the current bandRect, so just
-skip to the next band</li>
-    <li>case #3 and #4: rect is at least partially intersection with the
-bandRect, so divide the current band into two parts, where the top part is
-above the current rect. &nbsp;Move to the new band just created, which is
-the next band.</li>
-    <li>case #6: the rect shares the bottom and height with the bandRect,
-so just add the rect to the band.</li>
-    <li>case #4 and #7: create a new rect for the part that overlaps the
-bandRect, and add it to the current bandRect (similar to case #6) and then
-move on to the next band, removing that part from the rect passed in. &nbsp;If
-no more bands, append the rect passed in to the end of the bandRect list.</li>
-  </ul>
-</ul>
-<i>This algorithm is pretty confusing - basically what needs to happen is
-that rects and bands need to be divided up so that complicated cases like
-#2, #4, and #7, are reduced to simpler cases where the rects is totally above,
-below, or between a band rect. &nbsp;From the current implementation, it
-might be worth verifying that the final result of the inserts is a correctly
-ordered liest of bandRects (debug mode only).</i>
-
- 
-<h4>Algorithm 3: RemoveRegion</h4>
- When a float is removed, the Space Manager is notified by a call to RemoveRegion,
-passing in the frame that is being removed.
-
-<ul>
-  <li>Get the FrameInfo for the frame passed in. If not found, an error is
-returned.</li>
-  <li>If the rect for the frame is not empty, then visit each band in the
-bandList:</li>
-  <ul>
-    <li>for each rect in the band:
-
-    </li>
-  </ul>
-  <ul>
-    <ul>
-      <li>if the bandRect is occupied by the frame, either remove the frame
-from the bandRect (if there are other frames sharing it) and remember that
-it was shared</li>
-      <li>otherwise simply remove the bandRect (no other frames share it).</li>
-      <li>if the bandRect was shared, then try to coalesce adjacent bandRects</li>
-      <ul>
-        <li>if the previous bandRect is directly next to the current bandRect,
-and they have the same frame list, then make the current bandRect cover the
-previous bandRect's full region (adjust the left edge to be that of the previous
-bandRect) and remvoe the previous bandRect.</li>
-      </ul>
-    </ul>
-  </ul>
-  <ul>
-    <li>if the current band or prior band had a rect occupied byu the frame,
-then try to join the two bands via JoinBands</li>
-  </ul>
-  <li>Finally, destroy the frameInfo for the frame.

-<h1>Space Manager High Level Design</h1>
- <br>
- 
-<h2>Overview</h2>
-  The Space Manager and associated classes and strructures are used by Block 
-and Line layout to manage rectangular regions that are occupied and available, 
-for correct handling of floated elements and the elements that flow around 
-them. &nbsp;When elements are floated to the left or right in a layout, they 
-take up space and influence where other elements can be placed. &nbsp;The 
-Space Manager is responsible for keeping track of where space is taken up 
-and where it is available. This information is used by block layout to correctly 
-compute where other floated elements should be placed, and how much space 
-is available to normal in-flow elements that flow around the floated bits.<br>
- <br>
-  The Space Manager works in concert with several other classes to do its 
-job. The classes that are considered part of the Space Manager are:<br>
- 
-<ul>
-   <li>nsSpaceManager</li>
-   <li>nsBandData</li>
-   <li>nsBlockBandData</li>
-   <li>BandRect / BandList (private structs)</li>
-   <li>FrameInfo (private struct)</li>
-   <li>nsBandtrapezoid</li>
- 
-</ul>
-  Outside of the Space Manager itself, the clients of the Space Manager also
- play an inportant part in the management of he available and used space.
-&nbsp;The primary classes that interact witht eh Space Manager are:<br>
- 
-<ul>
-   <li>nsBlockReflowState</li>
-   <li>nsBlockFrame</li>
-   <li>nsBoxToBlockAdaptor</li>
- 
-</ul>
-  The general interaction model is to create a Space Manager for a block
-frame  in the context of a Reflow, and to associate it with the BlockReflowState
- so it is passed down to child frames' reflow methods. After reflow, the
-Space  Manager is destroyed. &nbsp;During reflow, the space manager stores
-the space  taken up by floats (UpdateSpaceManager in nsBlockFrame) and
-provides information  about the space available for other elements (GetAvailableSpace
-in nsBlockReflowState).  &nbsp;<br>
- <br>
- Additionally, there is a need to manage impacts to lines caused by
-changes to floated elements. &nbsp;This is referred to as Propagation
-of Float Damage and is handled by the Block Frame, making use of the
-Space Manager. When a float is incrementally reflowed, the Space
-Manger is notified if the float's region has changed. If so, the
-vertical space that has been affected (including both the float's old
-region and the float's new region) is noted in the internal
-nsIntervalSet as potential float damage (the method is
-IncludeInDamage).  During the incremental reflow of dirty lines the
-block frame may encounter lines that are NOT dirty. In this case the
-Space Manager is also asked if &nbsp;there is any float damage, and
-if there is then the block further checks to see if that damage
-intersects the area of the non-dirty line, marking it dirty if there

-  <ul>
-     <li>nsSpaceManager: The central point of management of the space taken
- up by floats in a block</li>
-     <li>nsBandData: Provides information about the frames occupying a band
- of occupied or available space</li>
-     <li>nsBlockBandData: A specialization of nsBandData that is used by

-where floats are  cleared. &nbsp;Essentially a CSS-specific wrapper for

-     <li>BandRect: Keeps the bounds of a band, along with the frames associated
- with the band. &nbsp;BandRects are a linked list (provided by PRCListStr
-super-class) and also provide some geometry-management methods (SplitVertically,
-SplitHorizontally) and some methods that query or manipulate the frames associated
-with the band (IsOccupiedBy, AddFrame, RemoveFrame).</li>
-     <li>BandList: A subclass of BandRect that provides a list interface

- associated with a specific frame, in a linked list.</li>
-     <li>nsBandTrapezoid: Represents the discrete regions within a band that

-of the nsBandTrapezoid by the Space Manager, rather it uses its internal
-BandList to create a BandData collection, which is largely made up of nsTrapezoid
-data.<br>
-     </li>
-   
-  </ul>
-   
-  <h2>Use Case</h2>
-   
-  <h4>Use Case 1: Space Manger is Created / Destroyed</h4>
-  Space Manager instances are created in the nsBlockFrame's Reflow method.
- &nbsp;<br>
-   
-  <ul>
-     <li>An instance is created&nbsp;</li>
-     <li>The BlockReflowState's previous Space Manger is saved off.</li>
-     <li>The new Space Manger instance is associated with the BlockReflowState. 
-&nbsp;</li>
-     <li>After the block frame's Reflow has completed, the old Space Manager 
-instance is re-associated with the BlockReflowState</li>
-     <li>The new Space Manager is destroyed.</li>
-   
-  </ul>
- If the BlockReflowState already had a Space Manager instance associated
-with  it, it is stored off before being replaced, and the returned to the
-BlockReflowState  instance after the new one has been destroyed. &nbsp;Thus,
-Space Managers  are effectively 'nested' during reflow, with each new block
-introducing its  own Space Manager.   
-
-  <h4>Use Case 2: Float is added to the Space Manager</h4>  After a Space Manager is created for a block context's reflow chain, a
-floated  block may be added to it. &nbsp;This happens in the method <i>nsBlockReflowState::RecoverFloats</i> and 
-<i>nsBlockReflowState::FlowAndPlaceFloat</i> (formerly this was done in nsBlockFrame::UpdateSpaceManager). &nbsp;<br>
-<br>
-The general algorightm in <i>nsBlockReflowState::RecoverFloats</i> is:<br>
-   
-  <ul>
-     <li>For each line in the block, see if it has floated blocks</li>
-     <li>If floats are in the line, iterate over the floats and add each
- one to the Space Manger via the AddRectRegion method. &nbsp;The actual rect
- for the frame is cached in an nsFloatCache so it does not have to be recomputed.</li>
-     <li>If the block has any block children, then translate the Space Manager
- to the child block's origin and update the space manager in the context
-for the child block, recursively. When done with the child, restore the Space
- Managers coordinates by translating by the negative of the child block's
-origin.&nbsp;       <br>
-     </li>
-   
-  </ul><br>
-
-The general algorightm in <i>nsBlockReflowState::FlowAndPlaceFloat</i> is:<br>
-<ul>
-  <li>The region that the float currently occupies is recorded.</li>
-  <li>The band of available space is searched (with nsBlockReflowState::GetAvailableSpace);</li>
-  <li>The float frame that is get from the passed nsFloatCache argument is reflowed
-  and its rect is retriven with GetRect;</li>
-  <li>The floats margins are added;</li>
-  <li>Check if the float can be placed in the acutal band: if not advance to the next band;</li>
-  <li>Check the float type and if it can be added to the space manager;</li>
-  <li>Align the float to its containing block top if rule 
-      <a href="http://www.w3.org/TR/REC-CSS2/visuren.html#float-position">CSS2/9.5.1/4</a>
-      is not respected;</li>
-  <li>Add the float using <i>nsSpaceManager::AddRectRegion</i> </li>
-  <li>Compare the area that the float used to occupy with the area that it now occupies: if different,
-      record the vertically affected interval using <i>nsSpaceManager::IncludeInDamage</i></li>
-</ul>
-  <h4>Use Case 3: Space Manager is used to find available space to reflow
- into</h4>
-  The nsBlockFrame makes use of the Space Manager indirectly to get the available
- space to reflow a child block or inline frame into. The block frame uses
-a helper method on the nsBlockReflowState class to do the actual computation
- of available space based on the data in the Space Manger. Here is how it
-works for reflowing an inline frame within a block (this also occurs for
-reflowing a block frame and, partially, for preparing for a resize reflow).<br>
-   
-  <ul>
-     <li>nsBlockFrame first frees all float information for the line that
- is being reflowed.</li>
-     <li>GetAvailableSpace is called on the BlockReflowState</li>
-     <li>the BlockReflowState calls GetAvailableSpace on its BlockBandData
- instance (which was setup in the BlockReflowState's constructor based on
-the SpaceManager passed in and computed content area).</li>
-     <li>BlockBandData then gets the band data from the space manager via
-a call to the Space Manager associated with the BlockBandData instance.</li>
-     <li>The BlockBandData then walks the collection of trapezoids that were
- returned by the SpaceManager method GetBandData (as nsBandData wrappers)
-and determines the right-most edge of the available space.</li>
-     <li>The BlockReflowState then stores this available space rect for use
- in the rest of the reflow chain.<br>
-     </li>
-   
-  </ul>
-   
-  <h4>Use Case 4: Propagation of Float Damage: detecting and handling float 
-damage</h4>
-  This process is driven by the Block Frame.<br>
-   
-  <ul>
-     <li>A non-dirty line is encountered by the Block Frame in ReflowDirtyLines</li>
-     <li>Block Frame calls its PropagateFloatDamage method</li>
-     <li>The Space Manger is checked to see if ther is any float damage</li>
-     <li>If there is, then the block frame asks the Space Manager if the
-line in question intersects the float damage</li>
-     <li>If the line does intersect a damage interval, then the line is marked 
-dirty</li>
-     <li>If the line does not intersect a damage interval, it may still be 
-marked dirty if:</li>
-     
-    <ul>
-       <li>it was impacted by floats before, but is not any longer</li>
-       <li>it was not impacted by floats befre, but is now</li>
-       <li><a name="block-line-impact"></a>
- it is impacted by floats and is a block<br>
-       </li>
-     
-    </ul>
-

-<h1>Layout System Overview</h1>
-<br>
-<h3>Layout's Job: Provide the Presentation</h3>
-Layout is primarily concerned with providing a presentation to an HTML or
-XML document. This presentation is typically formatted in accordance with
-the requirements of the <a href="http://www.w3.org/TR/REC-CSS1">CSS1</a>
-and <a href="http://www.w3.org/TR/REC-CSS2/">CSS2</a> specifications from
-the W3C. Presentation formatting is also required to provide compatibility
-with legacy browsers (Microsoft Internet Explorer and Netscape Navigator
-4.x). The decision about when to apply CSS-specified formatting and when
-to apply legacy formatting is controlled by the document's DOCTYPE specification.
-These layout modes are refered to as 'Standards' and 'NavQuirks' modes. (DOCTYPE
-and modes are explained in more detail <a
- href="http://www.mozilla.org/quality/help/bugzilla-helper.html">here</a>).<br>
-<br>
-The presentation generally is constrained by the width of the window in which
-the presentation is to be displayed, and a height that extends as far as
-necessary. This is referred to as the Galley Mode presentation, and is what
-one expects from a typical browser. Additionally, layout must support a paginated
-presentation, where the width of the presentation is constrained by the dimensions
-of the printed output (paper) and the height of each page is fixed. This
-paged presentation presents several challenges not present in the galley
-presentation, namely how to break up elements that are larger than a single
-page, and how to handle changes to page dimensions.<br>
-<br>
-The original design of the Layout system allowed for multiple, possibly different,
-presentations to be supported simultaneously from the same content model.
-In other words, the same HTML or XML document could be viewed as a normal
-galley presentation in a browser window, while simultaneously being presented
-in a paged presentation to a printer, or even an aural presentation to a
-speech-synthesizer. To date the only real use of this multiple presentation
-ability is seen in printing, where multiple presentations are managed, all
-connected to the same content model. (note: it is unclear if this is really
-a benefit - it may have been better to use a copy of the content model for
-each presentation, and to remove the complexity of managing separate presentations
-- analysis is needed here). The idea of supporting a non-visual presentation
-is interesting. Layout's support for aural presentations is undeveloped,
-though conceptually, it is possible and supported by the architecture.<br>
-<br>
-<h3>How Layout Does its Job: Frames and Reflow</h3>
-So, layout is concerned with providing a presentation, in galley or paged
-mode. Given a content model, how does the layout system actually create the
-presentation? Through the creation and management of frames. Frames are an
-encapsulation of a region on the screen, a region that contains geometry
-(size and location, stacking order). Generally frames correspond to the content
-elements, though there is often a one-to-many correspondence between content
-elements and frames. Layout creates frames for content based on either the
-specific HTML rules for an element or based on the CSS display type of the
-element. In the case of the HTML-specific elements, the frame types that
-correspond to the element are hard-coded, but in the more general case where
-the display type is needes, the layout system must determine that display
-type by using the Style System. A content element is passed to the Style
-System and a request is made to resolve the style for that element. This
-causes the Style System to apply all style rules that correspond to the element
-and results in a resolved Style Context - the style data specific to that
-element. The Layout module looks at the 'display' field of the style context
-to determine what kind of frame to create (block, inline, table, etc.). The
-style context is associated with the frame via a reference because it is
-needed for many other computations during the formatting of the frames.<br>
-<br>
-Once a frame is created for a content element, it must be formatted. We refer
-to this as 'laying out' the frame, or as 'reflowing' the frame. Each frame
-implements a Reflow method to compute its position and size, among other
-things. For more details on the Reflow mechanism, see the Reflow Overview
-document... &nbsp;The CSS formatting requirements present two distinct layout
-models: 1) the in-flow model, where the geometry of an element is influenced
-by the geometry of the elements that preceed it, and 2) the positioned model,
-where the geometry of an element is not influenced by the geometry of the
-elements that preceed it, or in any case, is influenced more locally. The
-in-flow cased is considered the 'normal' case, and corresponds to normal
-HTML formatting. The later case, called 'out of flow' puts the document author
-in control of the layout, and the author must specify the locations and sizes
-of all of the elements that are positioned. There is, of course, some complexity
-involved with managing these two models simultanelusly...<br>
-<br>
-So far the general flow of layout looks like this:<br>
-<br>
-1) Obtain a document's content model<br>
-2) Utilize the Style System to resolve the style of each element in the content
-model<br>
-3) Construct the frames that correspond to the content model, according to
-the resolved style data.<br>
-4) Perform the initial layout, or initial reflow, on the newly constructed
-frame.<br>
-<br>
-This is pretty straight-forward, but is complicated somewhat by the notion
-of <i>incrementalism</i>. One of the goals of the Layout system's design
-is to create parts of the presentation as they become available, rather than
-waiting for the entire document to be read, parsed, and then presented. This
-is a major benefit for large documents because the user does not have to wait
-for the 200th page of text to be read in before the first page can be displayed
-- they can start reading something right away. So really, this sequence of
-operations Resolve Style, Create Frame, Layout Frame, gets repeated many
-times as the content becomes available. In the normal in-flow case this is
-quite natural because the sequential addition of new content results in sequential
-addition of new frames, and because everything is in-flow, the new frames
-do not influence the geometry of the frames that have already been formatted.
-When out-of-flow frames are present this is a more difficult problem, however.
-Sometimes a content element comes in incrementally, and invalidates the formatting
-of some of the frames that preceed it, frame that have already been formatted.
-In this case the Layout System has to detect that impact and reflow again
-the impacted frames. This is referred to as an <i>incremental reflow</i>.<br>
-<br>
-<a name="DHTML_interaction"></a>Another responsibility of layout is to manage
-dynamic changes to the content model, changes that occur after the document
-has been loaded and (possibly) presented. These dynamic changes are caused
-by manipulations of the content model via the&nbsp;<acronym
- title="Document Object Model">DOM<acronym></acronym></acronym> (generally
-through java script). When a content element is modified, added or removed,
-Layout is notified. If content elements have been inserted, new frames are
-created and formatted (and impacts to other frames are managed by performing
-further incremental reflows). If content is removed, the corresponding frames
-are destroyed (again, impacts to other elements are managed). If a content
-element is modified, layout must determine if the chage influences the formatting
-of that or other elements' presentations, and must then reformat, or re-reflow,
-the impacted elements. In all cases, the determination of the impact is critical
-to avoid either the problem of not updating impacted elements, thus presenting
-an invalid presentation, or updating too much of the presentation and thus
-doing too much work, potentially causing performance problems.<br>
-<br>
-One very special case of dynamic content manipulation is the HTML Editor.
-Layout is used to implement both a full-blown WYSIWYG HTML editor, and a single
-and multi-line text entry control. In both cases, the content is manipulated
-by the user (via the DOM) and the resulting visual impacts must be shown as
-quickly as possible, without disconcerting flicker or other artifacts that
-might bother the user. Consider a text entry field: the user types text into
-a form on the web. As the user types a new character it is inserted into
-the content model. This causes layout to be notified that a new piece of
-content has been entered, which causes Layout to create a new frame and format
-it. This must happen very fast, so the user's typing is not delayed. In the
-case of the WYSIWYG HTML editor, the user expects that the modifications
-they make to the document will apear immediately, not seconds later. This
-is especially critical when the user is typing into the document: it would
-be quite unusable if typing a character at the end of a document in the HTML
-editor caused the entire document to be reformated - it would be too slow,
-at least on low-end machines. Thus the HTML editor and text controls put
-considerable performance requirements on the layout system's handling of dynamic
-content manipulation.<br>
-<h3>The Fundamentals of Frames: Block and Line</h3>
-There are many types of frames that are designed to model various formatting
-requirements of different HTML and XML elements. CSS2 defines several (block,
-inline, list-item, marker, run-in, compact, and various table types) and
-the standard HTML form controls require their own special frame types to
-be formatted as expected. The most essential frame types are Block and Inline,
-and these correspond to the most important Layout concepts, the Block and
-Line.<br>
-<br>
-A block is a rectangular region that is composed of one or more lines. A
-line is a single row of text or other presentational elements. All layout
-happens in the context of a block, and all of the contents of a block are
-formatted into lines within that block. As the width of a block is changed,
-the contents of the lines must be reformatted. consider for example a large
-paragraph of text sitting in paragraph:<br>
-<br>
-<pre>&lt;p&gt;<br> We need documentation for users, web developers, and developers working
- on Mozilla. If you write your own code, document it. Much of the
- existing code &lt;b&gt;isn&#8217;t very well documented&lt;/b&gt;. In the process of figuring 
- things out, try and document your discoveries. 
- If you&#8217;d like to contribute, let us know.<br>&lt;/p&gt;</pre>
-There is one block that corresponds to the &lt;p&gt; element, and then a number
-of lines of text that correspond to the text. As the width of the block changes
-(due to the window being resized, for example) the length of the lines within
-it changes, and thus more or less text appears on each line. The block is
-responsible for managing the lines. Note that lines may contain only inline
-elements, whereas block may contain both inline elements and other blocks.<br>
-<h3>Other Layout Models: XUL</h3>
-In addition to managing CSS-defined formatting, the layout system provides
-a way to integrate other layout schemes into the presentation. Currently
-layout supports the formatting of XUL elements, which utilize a constraint-based
-layout language. The Box is introduced into the layout system's frame model
-via an adapter (BoxToBlockAdapter) that translates the normal layout model
-into the box formatting model. Conceptually, this could be used to introduce
-other layout systems, but it might be worth noting that there was no specific
-facility designed into the layout system to accommodate this. Layout deals
-with frames, but as long as the layout system being considered has no need
-to influence presentational elements from other layout systems, it can be
-adapted using a frame-based adapter, ala XUL.<br>
-<br>
-<h2>Core Classes</h2>
-At the highest level, the layout system is a group of classes that manages
-the presentation within a fixed width and either unlimited height (galley
-presentation) or discrete page heights (paged presentation). Digging just
-a tiny bit deeper into the system we find that the complexity (and interest)
-mushrooms very rapidly. The idea of formatting text and graphics to fit within
-a given screen area sounds simple, but the interaction of in-flow and out-of-flow
-elements, the considerations of incremental page rendering, and the performance
-concerns of dynamic content changes makes for a system that has a lot of
-work to do, and a lot of data to manage. Here are the high-level classes
-that make up the layout system. Of course this is a small percentage of the
-total clases in layout (see the detailed design documents for the details
-on all of the classes, in the context of their actual role).<br>
-<h3>Presentation Shell / Presentation Context</h3>
-Together the presentation shell and the presentation context provide the
-root of the current presentation. The original design provided for a single
-Presentation Shell to manage multiple Presentation Contexts, to allow a single
-shell to handle multiple presentations. It is unclear if this is really possible,
-however, and in general it is assumed that there is a one-to-one correspondence
-between a presentation shell and a presentation context. The two classes
-should probably be folded into one, or the distinction between them formalized
-and utilized in the code. The Presentation Shell currently owns a controlling
-reference to the Presentation Context. Further references to the Presentation
-Shell and Presentation Context will be made by using the term Presentation
-Shell.<br>
-<br>
-The Presentation Shell is the root of the presentation, and as such it owns
-and manges a lot of layout objects that are used to create and maintain a
-presentation (<font color="#990000">note that the DocumentViewer is the owner
-of the Presentation Shell, and in some cases the creator of the objects
-used by the Presentation Shell to manage the presentation. More details
-of the Document Viewer are needed here...</font>). The Presentation Shell,
-or PresShell, is first and foremost the owner of the formatting objects,
-the frames. Management of the frames is facilitated by the Frame Manager,
-an instance of which the PresShell owns. Additionally, the PresShell provides
-a specialized storage heap for frames, called an Arena, that is used to make
-allocation and deallocation of frames faster and less likely to fragment
-the global heap. <br>
-<br>
-The Presentation Shell also owns the root of the Style System, the Style
-Set. In many cases the Presentation Shell provides pass-through methods to
-the Style Set, and generally uses the Style Set to do style resolution and
-Style Sheet management.<br>
-<br>
-One of the critical aspects of the Presentation Shell is the handling of
-frame formatting, or reflow. The Presentation Shell owns and maintains a
-Reflow Queue where requests for reflow are held until it is time to perform
-a reflow, and then pulled out and executed.<br>
-<br>
-It is also important to see the Presentation Shell as an observer of many
-kinds of events in the system. For example, the Presentation Shell receives
-notifications of document load events, which are used to trigger updates
-to the formatting of the frames in some cases. The Presentation Shell also
-receives notifications about changes in cursor and focus states, whereby
-the selection and caret updates can be made visible.<br>
-<br>
-There are dozens of other data objects managed by the Presentation Shell
-and Presentation Context, all necessary for the internal implementation.
-These data members and their roles will be discussed in the Presentation
-Shell design documents. For this overview, the Frames, Style Set, and Reflow
-Queue are the most important high-level parts of the Presentation Shell.<br>
-<h3>Frame Manager</h3>
-The Frame Manager is used to, well, manage frames. Frames are basic formatting
-objects used in layout, and the Frame Manager is responsible for making frames
-available to clients. There are several collections of frames maintained
-by the Frame Manager. The most basic is a list of all of the frames starting
-at the root frame. Clients generally do not want to incur the expense of
-traversing all of the frames from the root to find the frame they are interested
-in, so the Frame Manager provides some other mappings based on the needs of
-the clients.<br>
-<br>
-The most crucial mapping is the Primary Frame Map. This collection provides
-access to a frame that is designated as the primary frame for a piece of
-content. When a frame is created for a piece of content, it may be the 'primary
-frame' for that content element (content elements that require multiple
-frames have primary and secondary frames; only the primary frame is mapped).
-The Frame Manager is then instructed to store the mapping from a content
-element to the primary frame. This mapping facilitates updates to frames
-that result in changes to content (see <a href="#DHTML_interaction">discussion
-above</a>).<br>
-<br>
-Another important mapping maintained by the Frame Manager is that of the
-undisplayed content. When a content element is defined as having no display
-(via the CSS property 'display:none') it is noted by a special entry in the
-undisplayed map. This is important because no frame is generated for these
-elements yet changes to their style values and to the content elements still
-need to be handled by layout, in case their display state changes from 'none'
-to something else. The Undisplayed Map keeps track of all content and style
-data for elements that currently have no frames. (<font color="#990000">note:
-the original architecture of the layout system included the creation of frames
-for elements with no display. This changed somewhere along the line, but
-there is no indication of why the change was made. Presumably it is more
-time and space-efficient to prevent frame creation for elements with no display.)</font><br>
-<br>
-The Frame Manager also maintains a list of Forms and Form Controls, as <i>content
-nodes</i>. This is presumably related to the fact that layout is responsible
-for form submission, but this is a design flaw that is being corrected by
-moving form submission into the content world. These collections of Forms
-and Form Controls should be removed eventually.<br>
-<br>
-<h3>CSS Frame Constructor</h3>
-The Frame Constructor is responsible for resolving style values for content
-elements and creating the appropriate frames corresponding to that element.
-In addition to managing the creation of frames, the Frame Constructor is
-responsible for managing changes to the frames. Frame Construction is generally
-achieved by the use of stateless methods, but in some cases there is the
-need to provide context to frames created as children of a container. The
-Frame Manager uses the Frame Constructor State class to manage the important
-information about the container of a frame being created (<font
- color="#990000">and lots of other state-stuff too - need to describe more
-fully</font>).<br>
-<h3>Frame</h3>
-The Frame is the most fundamental layout object. The class nsFrame is the
-base class for all frames, and it inherits from the base class nsIFrame (note:
-nsIFrame is NOT an interface, it is an abstract base class. It was once an
-interface but was changed to be a base class when the Style System was modified
-- the name was not changed to reflect that it is not an interface). The Frame
-provides generic functionality that can be used by subclasses but cannot
-itself be instantiated.<br>
-<br>
-nsFrame:<br>
-The Frame provides a mechanism to navigate to a parent frame as well as child
-frames. All frames have a parent except for the root frame. The Frame is
-able to provide a reference to its parent and to its children upon request.
-The basic data that all frames maintain include: a rectangle describing the
-dimensions of the frame, a pointer to the content that the frame is representing,
-the style context representing all of the stylistic data corresponding to
-the frame, a parent frame pointer, a sibling frame pointer, and a series
-of state bits.<br>
-<br>
-Frames are chained primarily by the sibling links. Given a frame, one can
-walk the sibling of that frame, and can also navigate back up to the parent
-frame. Specializations of the frame also allow for the management of child
-frames; this functionality is provided by the Container Frame.<br>
-<br>
-Container Frames:<br>
-The Container Frame is a specialization of the base frame class that introduces
-the ability to manage a list of child frames. All frames that need to manage
-child frames (e.g. frames that are not themselves leaf frames) derive from
-Container Frame.<br>

-  <h2>Overview</h2>
-When a new style property is needed there are many places in the code that
-need to be updated. This document outlines the proceedure used to add a new
-property, in this case the property is a proprietary one called '-moz-force-broken-image-icons'
-and is used as a way for a stylesheet to force broken image icons to be displayed.
-This is all being done in the context of <a href="http://bugzilla.mozilla.org/show_bug.cgi?id=58646">
-bug 58646</a>.
-
-  <h2>Analysis</h2>
-<p>Up front you have to decide some things about the new property:</p>
-
-<p><b>Questions:</b></p>
-  <ol>
-    <li>Is the property proprietary or specified by the CSS standard?</li>
-    <li>Is the property inherited?</li>
-    <li>What types of values can the property have?</li>
-    <li>Does it logically fit with other existing properties?</li>
-    <li>What is the impact to the layout of a page if that property changes?</li>
-    <li>What do you want to name it?</li>
-  </ol>
-<p><b>Answers:</b></p>
-  <ol>
-    <li>In our specific case, we want a property that is used internally,
-so it is a proprietary property.</li>
-    <li>The property is to be used for images, which are leaf elements, so
-there is no need to inherit it.</li>
-    <li>The property is used simply to force a broken image to be represented
-by an icon, so it only supports the values '0' and '1' as numerics. </li>
-    <li>It is hard to see how this property fits logically in with other
-properties, but if we stretch our imaginations we could say that it is a
-sort of UI property.</li>
-    <li>If this property changes, the image frame has to be recreated. This
-is because the decision about whether to display the icon or not will impact
-the decision to replace the image frame with an inline text frame for the
-ALT text, so if the ALT text inline is already made, there is no image frame
-left around to reflow or otherwise modify.</li>
-    <li>Finally, the name will be '-moz-force-broken-image-icons' - that
-should be pretty self-describing (by convention we start proprietary property
-names with '-moz-').</li>
-  </ol>
-  <h2>Implementation</h2>
-
-<p>There are several places that need to be educated about a new style property.
-They are:
-</p>
-  <ul>
-    <li><a href="#CSSPropList">CSS Property Names and Hint Tables</a>: the new
-property name must be made formally know to the system</li>
-    <li><a href="#CSSDeclaration">CSS Declaration</a>: the declaration must be
-able to hold the property and its value(s)</li>
-    <li><a href="#Parser">CSS Parser</a>: the parser must be able to parse the
-property name, validate the values, and provide a declaration for the property
-and value</li>
-    <li><a href="#StyleContext">Style Context</a>: the StyleContext must be able
-to hold the resolved value of the property, and provide a means to retrieve the
-property value. Additionally, the StyleContext has to know what kind of impact a
-change to this property causes.</li>
-    <li><a href="#RuleNode">Rule Nodes</a>: the RuleNodes need to know how the
-property is inherited and how it is shared by other elements.</li>
-    <li><a href="#DOM">DOM</a>: Your style should be accessible from the DOM so
-users may dynamically set/get its property value.</li>
-    <li><a href="#Layout">Layout</a>: layout has to know what to do with the
-property, in other words, the meaning of the property.</li>
-  </ul>
-  <h3><a name="CSSPropList">CSS Property Name / Constants / Hints</a></h3>
-
-<p>
-First, add the new name to the property list in <a href="http://lxr.mozilla.org/seamonkey/source/content/shared/public/nsCSSPropList.h">
-nsCSSPropList.h</a>
-  Insert the property in the list alphabetically, using the existing
-property names as a template. The format of the entry you will create is:
-</p>
-  <pre>CSS_PROP(-moz-force-broken-image-icons, force_broken_image_icons, MozForceBrokenImageIcons, NS_STYLE_HINT_FRAMECHANGE) // bug 58646</pre>
-
-<p>The first value is the formal property name, in other words the property
-name as it is seen by the CSS parser.<br>
-The second value is the name of the property as it will appear internally.<br>
-The third value is the name of the DOM property used to access your style.<br>
-The last value indicates what must change when the value of the property
-changes. It should be an
-<a href="http://lxr.mozilla.org/seamonkey/source/content/shared/public/nsChangeHint.h">nsChangeHint</a>.</p>
- 
-<p>If you need to introduce new constants for the values of the property, they
-must be added to <a href="http://lxr.mozilla.org/seamonkey/source/layout/base/public/nsStyleConsts.h">
-nsStyleConsts.h</a>
- and to the appropriate keyword tables in <a href="http://lxr.mozilla.org/seamonkey/source/content/shared/src/nsCSSProps.cpp">
-nsCSSProps.cpp</a>
- (note: this cookbook does not do this since the new property does not require
-any new keywords for the property values).
-  <h3><a name="CSSDeclaration">CSS Declaration</a></h3>
-Changes will need to be made to the structs and classes defined in <a href="http://lxr.mozilla.org/seamonkey/source/content/html/style/src/nsCSSDeclaration.h">
-nsCSSDeclaration.h </a>
-and <a href="http://lxr.mozilla.org/seamonkey/source/content/html/style/src/nsCSSDeclaration.cpp">
-nsCSSDeclaration.cpp</a>
-  <br>
-  <br>
-First, find the declaration of the struct that will hold the new property
-value (in the header file). For this example it is the struct <b>nsCSSUserInterface</b>
-. Modify the struct declaration to include a new data member for the new
-property, of the type CSSValue. Next, open the implementation file (the cpp)
-and modify the struct's constructors. <br>
-  <br>
-Next, the <a href="http://lxr.mozilla.org/seamonkey/source/content/html/style/src/nsCSSDeclaration.cpp#1410">
-AppendValue</a>
- method must be updated to support your new property. The CSSParser will
-call this to build up a declaration. Find the portion of that method that
-deals with the other properties in the struct that you are adding your property
-to (or create a new section if you are creating a new style struct). For
-this example we will find the 'UserInterface' section and add our new property
-  <a href="#AppendValueCase">there</a>

- 
-  <h3><a name="Parser">CSS Parser</a></h3>
-Next, the CSSParser must be educated about this new property so that it can
-read in the formal declarations and build up the internal declarations that
-will be used to build the rules. If you are adding a simple property that
-takes a single value, you simply add your new property to the ParseSingleProperty
-method. If a more complex parsing is required you will have to write a new
-method to handle it, modeling it off of one of the existing parsing helper
-methods (see <a href="http://lxr.mozilla.org/seamonkey/source/content/html/style/src/nsCSSParser.cpp#4151">
-ParseBackground</a>
-, for and example). We are just adding a simple single-value property here.<br>
-  <br>
-Open nsCSSParser.cpp and look for the method <a href="http://lxr.mozilla.org/seamonkey/source/content/html/style/src/nsCSSParser.cpp#3580">
-ParseSingleProperty</a>
-. This method is responsible for calling the relevant helper routine to parse
-the value(s). Find an existing property that is similar to the property you
-are adding. For our example we are adding a property that takes a numeric
-value so we will model it after the 'height' property and call ParsePositiveVariant.
-Add a new case for the new property and call the appropriate parser-helper
-and make a call to ParseVariant passing the <a href="http://lxr.mozilla.org/seamonkey/source/content/html/style/src/nsCSSParser.cpp#2754">
-variant flag</a>
- that makes sense for your property. In our case<br>
-  <br>
-  <pre>  case eCSSProperty_force_broken_image_icons:</pre>
-  <pre>    return ParsePositiveVariant(aErrorCode, aValue, VARIANT_INTEGER, nsnull);</pre>
-This will parse the value as a positive integer value, which is what we want.<br>
-  <br>
-  <h3><a name="StyleContext">Style Context</a></h3>
-Having implemented support for the new property in the CSS Parser and CSS
-Declaration classes in the content module, it is now time to provide support
-for the new property in layout. The Style Context must be given a new data
-member corresponding to the declaration's new data member, so the computed
-value can be held for the layout objects to use.<br>
-  <br>
-First look into <a href="http://lxr.mozilla.org/seamonkey/source/content/shared/public/nsStyleStruct.h">
-nsStyleStruct.h</a>
- to see the existing style strucs. Find the one that you want to store the
-data on. In this example, we want to put it on the nsStyleUserInterface struct,
-however there is also a class nsStyleUIReset that holds the non-inherited
-values, so we will use that one (remember, our property is not inherited).
-Add a <a href="#StyleContextMember">data member</a>
- to hold the value:
-  <pre>struct nsStyleUIReset: public nsStyleStruct {
-  nsStyleUIReset(void);
-  nsStyleUIReset(const nsStyleUIReset&amp; aOther);
-  ~nsStyleUIReset(void);
-
-  NS_DEFINE_STATIC_STYLESTRUCTID_ACCESSOR(eStyleStruct_UIReset)
-
-  void* operator new(size_t sz, nsPresContext* aContext) {
-    return aContext->AllocateFromShell(sz);
-  }
-  void Destroy(nsPresContext* aContext) {
-    this-&gt;~nsStyleUIReset();
-    aContext-&gt;FreeToShell(sizeof(nsStyleUIReset), this);
-  };
-
-  PRInt32 CalcDifference(const nsStyleUIReset&amp; aOther) const;
-
-  PRUint8   mUserSelect;      // [reset] (selection-style)
-  PRUnichar mKeyEquivalent;   // [reset] XXX what type should this be?
-  PRUint8   mResizer;         // [reset]
-  <b><a name="StyleContextMember"></a>PRUint8   mForceBrokenImageIcon; // [reset]  (0 if not forcing, otherwise forcing)</b>
-};
-</pre>
-In the implementation file <a href="http://lxr.mozilla.org/seamonkey/source/content/shared/src/nsStyleStruct.cpp">
-nsStyleContext.cpp </a>
-add the new data member to the constructors of the style struct and the CalcDifference
-method, which must return the correct style-change hint when a change to
-your new property is detected. The constructor changes are obvious, but here
-is the CalcDifference change for our example:<br>
-  <pre>PRInt32 nsStyleUIReset::CalcDifference(const nsStyleUIReset&amp; aOther) const
-{
- <b> if (mForceBrokenImageIcon == aOther.mForceBrokenImageIcon) {</b>
-    if (mResizer == aOther.mResizer) {
-      if (mUserSelect == aOther.mUserSelect) {
-        if (mKeyEquivalent == aOther.mKeyEquivalent) {
-          return NS_STYLE_HINT_NONE;
-        }
-        return NS_STYLE_HINT_CONTENT;
-      }
-      return NS_STYLE_HINT_VISUAL;
-    }
-    return NS_STYLE_HINT_VISUAL;
-  }
-  <b>return NS_STYLE_HINT_FRAMECHANGE;
-</b>}
-</pre>
-  <h3>CSSStyleRule</h3>
-The nsCSSStyleRule must be updated to manage mapping the declaration to the
-style struct. In the file <a href="http://lxr.mozilla.org/seamonkey/source/content/html/style/src/nsCSSStyleRule.cpp">
-nsCSSStyleRule.cpp</a>
-, locate the Declaration mapping function corresponding to the style struct
-you have added your property to. For example, we <a href="http://bugzilla.mozilla.org/MapUIForDeclChange">
-update </a>
-MapUIForDeclaration:<br>
-  <pre>static nsresult
-MapUIForDeclaration(nsCSSDeclaration* aDecl, const nsStyleStructID&amp; aID, nsCSSUserInterface&amp; aUI)
-{
-  if (!aDecl)
-    return NS_OK; // The rule must have a declaration.
-
-  nsCSSUserInterface* ourUI = (nsCSSUserInterface*)aDecl-&gt;GetData(kCSSUserInterfaceSID);
-  if (!ourUI)
-    return NS_OK; // We don't have any rules for UI.
-
-  if (aID == eStyleStruct_UserInterface) {
-    if (aUI.mUserFocus.GetUnit() == eCSSUnit_Null &amp;&amp; ourUI-&gt;mUserFocus.GetUnit() != eCSSUnit_Null)
-      aUI.mUserFocus = ourUI-&gt;mUserFocus;
-    
-    if (aUI.mUserInput.GetUnit() == eCSSUnit_Null &amp;&amp; ourUI-&gt;mUserInput.GetUnit() != eCSSUnit_Null)
-      aUI.mUserInput = ourUI-&gt;mUserInput;
-
-    if (aUI.mUserModify.GetUnit() == eCSSUnit_Null &amp;&amp; ourUI-&gt;mUserModify.GetUnit() != eCSSUnit_Null)
-      aUI.mUserModify = ourUI-&gt;mUserModify;
-
-    if (!aUI.mCursor &amp;&amp; ourUI-&gt;mCursor)
-      aUI.mCursor = ourUI-&gt;mCursor;
-
-
-  }
-  else if (aID == eStyleStruct_UIReset) {
-    if (aUI.mUserSelect.GetUnit() == eCSSUnit_Null &amp;&amp; ourUI-&gt;mUserSelect.GetUnit() != eCSSUnit_Null)
-      aUI.mUserSelect = ourUI-&gt;mUserSelect;
-   
-    if (!aUI.mKeyEquivalent &amp;&amp; ourUI-&gt;mKeyEquivalent)
-      aUI.mKeyEquivalent = ourUI-&gt;mKeyEquivalent;
-
-    if (aUI.mResizer.GetUnit() == eCSSUnit_Null &amp;&amp; ourUI-&gt;mResizer.GetUnit() != eCSSUnit_Null)
-      aUI.mResizer = ourUI-&gt;mResizer;
-    <b>
-    <a name="MapUIForDeclChange"></a>if (aUI.mForceBrokenImageIcon.GetUnit() == eCSSUnit_Null &amp;&amp; ourUI-&gt;mForceBrokenImageIcon.GetUnit() == eCSSUnit_Integer)
-      aUI.mForceBrokenImageIcon = ourUI-&gt;mForceBrokenImageIcon;</b>
-  }
-
-  return NS_OK;
-
-}
-</pre>
-  <h3><a name="RuleNode">Rule Node</a></h3>
-Now we have to update the RuleNode code to know about the new property. First,
-locate the PropertyCheckData array for the data that you added the new property
-to. For this example, we add the following:<br>
-  <pre>static const PropertyCheckData UIResetCheckProperties[] = {
-  CHECKDATA_PROP(nsCSSUserInterface, mUserSelect, CHECKDATA_VALUE, PR_FALSE),
-  CHECKDATA_PROP(nsCSSUserInterface, mResizer, CHECKDATA_VALUE, PR_FALSE),
-  CHECKDATA_PROP(nsCSSUserInterface, mKeyEquivalent, CHECKDATA_VALUELIST, PR_FALSE)
-  <b>CHECKDATA_PROP(nsCSSUserInterface, mForceBrokenImageIcon, CHECKDATA_VALUE, PR_FALSE)</b>
-};
-</pre>
-The first two arguments correspond to the structure and data member from
-the CSSDeclaration, the third is the data type, the fourth indicates
-whether it is a coord value that uses an explicit inherit value on the
-style data struct that must be computed by layout.<br>
-  <br>
-Next, we have to make sure the ComputeXXX method for the structure the property
-was added to is updated to mange the new value. In this example we need to
-modify the nsRuleNode::ComputeUIResetData method to handle the CSS Declaration
-to the style struct:<br>
-  <pre>  ...
-  // resizer: auto, none, enum, inherit
-  if (eCSSUnit_Enumerated == uiData.mResizer.GetUnit()) {
-    ui-&gt;mResizer = uiData.mResizer.GetIntValue();
-  }
-  else if (eCSSUnit_Auto == uiData.mResizer.GetUnit()) {
-    ui-&gt;mResizer = NS_STYLE_RESIZER_AUTO;
-  }
-  else if (eCSSUnit_None == uiData.mResizer.GetUnit()) {
-    ui-&gt;mResizer = NS_STYLE_RESIZER_NONE;
-  }
-  else if (eCSSUnit_Inherit == uiData.mResizer.GetUnit()) {
-    inherited = PR_TRUE;
-    ui-&gt;mResizer = parentUI-&gt;mResizer;
-  }
-
-  <b>// force-broken-image-icons: integer, inherit, -moz-initial
-  if (eCSSUnit_Integer == uiData.mForceBrokenImageIcons.GetUnit()) {
-    ui-&gt;mForceBrokenImageIcons = uiData.mForceBrokenImageIcons.GetIntValue();
-  } else if (eCSSUnit_Inherit == uiData.mForceBrokenImageIcons.GetUnit()) {
-    inherited = PR_TRUE;
-    ui-&gt;mForceBrokenImageIcons = parentUI-&gt;mForceBrokenImageIcons;
-  } else if (eCSSUnit_Initial == uiData.mForceBrokenImageIcons.GetUnit()) {
-    ui-&gt;mForceBrokenImageIcons = 0;
-  }</b>
-  
-  if (inherited)
-    // We inherited, and therefore can't be cached in the rule node.  We have to be put right on the
-    // style context.
-    aContext-&gt;SetStyle(eStyleStruct_UIReset, *ui);
-  else {
-    // We were fully specified and can therefore be cached right on the rule node.

-  }

-</pre>
-  <h3><a name="DOM">DOM</a></h3>
-Users in scripts, or anywhere outside of layout/ or content/ may need to access
-the new property.  This is done using the CSS OM, specifically
-<code>nsIDOMCSSStyleDeclaration</code>, <code>nsIDOMCSS2Properties</code>, and
-<code>nsIDOMNSCSS2Properties</code>.  By the magic of C++ pre-processing, the
-CSS2Properties interfaces will be implemented automatically when you
-<a href="#CSSPropList">add your property</a> to <a href="http://lxr.mozilla.org/seamonkey/source/content/shared/public/nsCSSPropList.h">
-nsCSSPropList.h</a>. Because of this, if you fail to add your property to the
-DOM interface, you will be rewarded with compiler errors.  All you have to do
-is modify <a href="http://lxr.mozilla.org/mozilla/source/dom/public/idl/css/nsIDOMCSS2Properties.idl">
-nsIDOMCSS2Properties.idl</a> and add the appropriate attribute to the
-<code>nsIDOMNSCSS2Properties</code> interface (lower in the file).
-For example:<br>
-  <pre>           attribute DOMString        MozForceBrokenImageIcon;
-                                        // raises(DOMException) on setting
-
-</pre>
-  <h3><a name="Layout">Layout</a></h3>
-OK, finally the style system is supporting the new property. It is time to
-actually make use of it now.<br>
-  <br>
-In layout, retrieve the styleStruct that has the new property from the frame's
-style context. Access the new property and get its value. It is that simple.
-For this example, it looks like this, in nsImageFrame:<br>
-  <pre>        PRBool forceIcon = PR_FALSE;
-
-        const nsStyleUIReset* styleData;
-        GetStyleData(eStyleStruct_UIReset, (const nsStyleStruct*&amp;) styleData);
-        if (styleData-&gt;mForceBrokenImageIcon) {
-          forceIcon = PR_TRUE;
-        }
-
-</pre>
-Create some testcases with style rules that use the new property, make sure
-it is being parsed correctly. Test it in an external stylesheet and in inline
-style. Test that it is inherited correctly, or not inherited as appropriate
-to your property. Update this document with any further details, or correcting
-any errors.<br>

-<body>
- <h1>Debugging facilities in HTML-table code</h1>
- <h2>Reflow</h2>
- <p>The most efficient tool to claim that html-table code is the victim and not the source of layout bugs is a  <a href="http://lxr.mozilla.org/seamonkey/source/layout/doc/frame_reflow_debug.html">frame reflow  debug log</a>.  Look there especially how the maxElementsize (MES)  and desired size are propagated.
-
- <h2>Block Reflow</h2>
-<p>
-Another possibilty to debug the reflow process is implemented inside <a href="http://lxr.mozilla.org/seamonkey/source/layout/html/base/src/nsBlockFrame.cpp">nsBlockFrame.cpp</a>. It can be invoked by<p>
-<code>set GECKO_BLOCK_DEBUG_FLAGS=reflow</code>
-<p>
-The available options are:
-<ul>
-<li><code>reflow</code>
-<li> <code>really-noisy-reflow</code>
-<li><code>max-element-size</code>
-<li><code> space-manager</code>
-<li><code>verify-lines</code>
-<li><code>damage-repair</code>
-<li><code>lame-paint-metrics</code>
-<li><code>lame-reflow-metrics</code>
-<li><code>disable-resize-opt</code>
-</ul>
-<p>
-These options can be combined with a comma separated list 
-Messages generated by the <code>reflow</code> switch:
-<ul>
-<li><code> Block(div)(1)@00BE5AC4: reflowing dirty lines computedWidth=9000 computedHeight=1500</code>
-<ul>
-<li> this message is generated inside of <br>
-<code>nsresult nsBlockFrame::ReflowDirtyLines(nsBlockReflowState& aState)</code>
-<li> it first shows the Block ID and Address
-<li>and then the computed width and Height from the HTMLReflowState.
-</ul>
-</ul>
-
-<h2>DEBUG_TABLE_STRATEGY</h2>
-<p>
-The table layout strategy can be visualized by defining in the <a href="http://lxr.mozilla.org/seamonkey/source/layout/html/table/src/Makefile.in">makefiles</a> the constant DEBUG_TABLE_STRATEGY.
-
-If one takes for instance the following table
-<table cellspacing="10"><tr><th>rendering</th><th>code</th></tr>

-<h1>Debugging Frame Reflow HowTo</h1>
-<h2>General Overview</h2>
-<p> The frame reflow can be logged with the debug capabilties implemented in <a href="http://lxr.mozilla.org/seamonkey/source/layout/html/base/src/nsFrame.cpp"><code>nsFrame.cpp</code></a>. 
-It provides the following information for each frame at the
-start of its reflow
-<ul>
-<li>reflow reason
-<li>available width, available height
-<li>computed width, computed height
-<li>the previous and the next frame in flow
-<li>and a count number.
-</ul>
-<p>When the frame's reflow is finished the following information is displayed :</p>
-<ul>
-<li>reflow metric (desired)  width, height
-<li>max. element size (MES) width
-<li>maximum Width
-<li>frame status
-<li>overflow area
-</ul>
-
-<h2>Getting the log</h2>
-<ul>
-<li>Make sure that your build is a <b>debug</b> build.
-<li>Create a text file (for instance <code>reflow_rules.txt</code>).
-<li>Enter this line  in the text file <pre>* 1</pre>
-<li>Save the text file in the <code>%DIST%</code> directory
-<li>Go to the <code>%DIST%</code> directory
-<li>enter from command line: <code>set GECKO_DISPLAY_REFLOW_RULES_FILE=reflow_rules.txt</code>
-<li> Run <code>viewer &gt; logfile.txt</code> and load your testcase. The
-logfile will contain all the promised information.

-The first line shows the reflow of the viewport (<code class="log">VP</code>). This viewport has the address <code class="log">00B97C30</code>. It is the initial reflow: <code class="log">r=0</code>. Other reflow reasons are: </p>
-<table>
-<tr><td>1</td><td>incremental reflow</td></tr>
-<tr><td>2</td><td>resize reflow</td></tr>
-<tr><td>3</td><td>style change reflow</td></tr>
-<tr><td>4</td><td>dirty reflow.</td></tr>
-</table>
-
-<p>The available width is 9180 twips. The available height is 4470 twips (<code class="log">a=9180,4470</code>). The computed width is 9180 twips. The computed height is 4470 twips (<code class="log">c=9180,4470</code>). The line count is 856 (<code  class="log">cnt=856</code>).
-<p>
-Below this is a line that reads:<p><code class="log">tblO 02D7B5F0 r=0 a=8940,UC c=0,0 cnt=870</code></p><p> Here the <code class="log">UC</code> shows that on initial reflow the available height for the outer table frame is unconstrained.
-<p>
-The table cell requires its children to compute the MES. It is reported back from the block as:
-<p><code class="log">block 02D7BCF8 d=300,300 me=300</code></p>
-<p>The  block max. element size is 300 twips.
-<p> The second table reflow is started at 
-<p><code class="log">rowG 00B984A4 r=2 a=1500,UC c=1500,UC cnt=879</code></p>
-<p>where the previous information is used. 
-The block has been required to compute the max. element size only once and it reports now:
-<p> <code class="log">block 02D7BCF8 d=1410,300</code></p>
-<p>The block shows the same address as the previous one. 
-<p>Frames with children that overflow  the parent have the <code>NS_FRAME_OUTSIDE_CHILDREN</code> flag set. For these frames 
-the overflowarea  is displayed as  <code class="log">block 025ED8F0 d=8940,1020 o=(0,0) 9180 x 1020</code>. The overflow area is specified as (x,y) origin and width x height.
-<p> The reflow finishes at the same level where it started.
-
-<h2>Advanced reflow debugging</h2>
-<p>The previously described technique dumps the data for every frame. Sometimes the log is clearer if only the main frames are shown.
-The entries in the reflow log can be controlled on a frame level.  For instance adding <code>text 0</code> to the rules in <code>reflow_rules.txt</code> would hide the text entries from the reflow. The display of the following frames can be turned on by adding a line with the frame name and  <code>1</code>  or turned off by adding a line with the frame name and <code>0</code>:</p>
-<table cellspacing="5">
- <tr><th style="text-align:left">short name</th><th style="text-align:left">layout tag</th></tr>
- <tr><td>area</td><td>area</td></tr>
- <tr><td>block</td><td>block</td></tr>
- <tr><td>br</td><td>br</td></tr>
- <tr><td>bullet</td><td>bullet</td></tr>
- <tr><td>button</td><td>gfxButtonControl</td></tr>
- <tr><td>hr</td><td>hr</td></tr>
- <tr><td>frameI</td><td>htmlFrameInner</td></tr>
- <tr><td>frameO</td><td>htmlFrameOuter</td></tr>
- <tr><td>img</td><td>image</td></tr>

- <tr><td>letter</td><td>letter</td></tr>
- <tr><td>line</td><td>line</td></tr>
- <tr><td>select</td><td>select</td></tr>

-</table>
-<p>Once the problem is reduced to a single frame level, placing a breakpoint at <code>DisplayReflowEnterPrint</code> in <a href="http://lxr.mozilla.org/seamonkey/source/layout/html/base/src/nsFrame.cpp"><code>nsFrame.cpp</code></a> is a very efficient way to step through
- the reflow tree.
-
-<h2>Other reflow debug options</h2>
-
-<h3>GECKO_DISPLAY_REFLOW_FLAG_PIXEL_ERRORS</h3>
-<p>
-Setting this option via <code>set GECKO_DISPLAY_REFLOW_FLAG_PIXEL_ERRORS = 1</code> enables a verification for each coordinate value that the coordinates are aligned at pixel boundaries.
-<table class="log"><tr><td>
-<pre>
-              row 0268A594 r=0 a=UC,UC c=UC,20 cnt=870 
-VALUE 20 is not a whole pixel 
-               cell 0268A6C0 r=0 a=UC,UC c=UC,15 cnt=871 
-                block 0268A764 r=0 a=UC,UC c=UC,UC cnt=872 
-                block 0268A764 d=0,0 me=0 
-               cell 0268A6C0 d=0,0 me=0 
-              row 0268A594 d=UC,20 
-VALUE 20 is not a whole pixel 
-             rowG 0268A02C d=UC,695 
-VALUE 695 is not a whole pixel</pre>
-</td></tr></table>
-<p>
-While unaligned values at the entrance of a frame reflow can be ignored,  when they appear at the exit of a routine this can cause display errors like stray lines. OS2 is very vulnerable to pixel alignement errors as text is drawn on pixel boundaries.
-
-<h3>GECKO_DISPLAY_REFLOW_INDENT_UNDISPLAYED_FRAMES</h3>
-<p>
-Setting this option via <code>set GECKO_DISPLAY_REFLOW_INDENT_UNDISPLAYED_FRAMES = 1</code> will cause an advance of the indent even for frames which are blocked via the reflow rules file.

- in mind that this is just a general template intended for most designs.
-Your  specific design may require different organization or topics - the
-goal is  to provide high-level information about the software to the reader.]<br>
-  <br>
-  
-<h1>[Component/Class/System Name] High Level Design</h1>
-  <br>
-  
-<h2>Overview</h2>
-   [Provide a descriptive overview of the component, class, or system that
- you are documenting. Describe what the system is supposed to do, where it
- is in the overall system, who the clients are, how it is expected to perform, 
- and any other information that is important to convey to somebody interested 
- in understanding what the documented system is all about.]<br>
-  <br>
-  
-<h2>Data Model</h2>
-   [This section describes the classes or components that make up the data
- model for the system being documented. It can include a graphical representation 
- of the classes and their relationships to each other (derivation, aggregation, 
- ownership, usership, etc.). No implementation details are to be included 
-here, but general relationships and inter-relationships should be shown and 
-briefly described. The reader should be able to understand the players in 
-the system, and the extent to which those players interact with or are related 
-to the other players.]<br>

-  <h2>Use Case</h2>
-   [Use Cases describe interactions between specific instances of the objects 
- or components described in the Data Model. &nbsp;There will generally be 
-use cases for each &nbsp; interesting runtime interaction between the objects 
- in the system. An extremely simple system will have at least one use case 
- describing the behavior of the simple system in action, but most systems 
-have many use cases corresponding to the any things that the system does. 
-&nbsp;The reader should be able to find the use case (or cases) that correspond 
-to the situation they are interested in understanding, and they should be 
-able to learn how data flows through the system, what objects are involved, 
-how &nbsp;object and data life-cycles are managed (e.g. where allocations 
-ad deallocations occur, and who maintains ownership). This section makes up
-the bulk of the document. It touches on implementations and algorithms, but
-rather than describing them in detail, it stays high-level and links to the
-detailed designs that correspond.]<br>
-      
-  <h4>[Use Case 1: Component is Created]</h4>

-ownership,  etc. goes here]<br>
-      
-  <h2>State Transitions</h2>
-   [Where appropriate, the discrete states of a system should be enumerated 
- and the transitions between the states defined. &nbsp;Not all systems require 
- full state transition diagrams, but most systems have at least a handful 
-of interesting states, and at least a small number of interesting stimuli 
-that cause transitions from one state to another. &nbsp; Of course, classes 
-or components that are not stateful have no need for this section.]<br>

-<h1>
-<u>Block Layout</u></h1>
-This document attempts to describe how "block" layout works in the mozilla
-layout engine.
-<p><tt>nsBlockFrame</tt> implements layout behavior that conforms to the
-CSS "display:block" and "display: list-item" layout. It has several responsibilities:
-<ol>
-<li>
-&nbsp;Line layout. The block is responsible for flowing inline elements
-into "lines" and applying all of the css behavior as one might expect,
-including line-height, vertical-align, relative positioning, etc.</li>
-
-<li>
-Float management. The block is responsible for the reflow and placement
-of floating elements.</li>
-
-<li>
-Child block management. Blocks can contain inline elements and block elements.
-Hence, blocks are responsible for reflowing child blocks. The majority
-of that logic has been split out into nsBlockReflowContext, but a fair
-amount remains here.</li>
-
-<li>
-Supporting table reflow. The block has to carefully compute the "max-element-size"
-information needed by tables. Hence, any time changes are made here one
-should always run the table regression tests because the odds are you broke
-one of them!</li>
-</ol>
-
-<h3>
-<u>The Big Picture for Block Reflow</u></h3>
-The block frame uses a list of nsLineBox's to keep track of each "line"
-of frames it manages. There are two types of lines:
-<blockquote>"inline" lines which contain only inline elements
-<br>"block" lines which contain exactly one block element</blockquote>
-Each line has a "dirty" bit which indicates that it needs reflow. Reflow
-consists of identifying which lines need to be marked dirty and then reflowing
-all lines. For lines which are "clean" the reflow logic will endeavor to
-recover the state of reflow <i>as if the line had been reflowed</i>. This
-saves time and allows for a faster incremental reflow. For lines which
-are dirty, the line is reflowed appropriately.
-<p>The only special thing about incremental reflow command handling is
-that it marks lines dirty before proceeding, and keeps track of the child
-frame that is the next frame on the reflow command path.
-<p>Here is a list of the various classes involved in block layout:
-<p><b>nsBlockFrame</b>
-<blockquote>The primary culprit.</blockquote>
-<b>nsBlockReflowState</b>
-<blockquote>This helper class is used to augment the nsHTMLReflowState
-with other information needed by the block reflow logic during reflow.
-It is a temporary object that is designed to live on the processor stack
-and contains "running" state used by the blocks reflow logic.</blockquote>
-<b>nsBlockBandData</b>
-<blockquote>Another helper class that wraps up management of a space manager
-(nsISpaceManager, nsSpaceManager) and nsBandData. It also assists in management
-of floating elements. While nsSpaceManager is policy free, nsBlockBandData
-provides specific HTML and CSS policy.</blockquote>
-<b>nsBlockReflowContext</b>
-<blockquote>A helper class that encapsulates the logic needed to reflow
-a child block frame. This is used by the block code reflow a child block
-and to reflow floating elements (which are to be treated as blocks according
-to the CSS2 spec).</blockquote>
-<b>nsLineBox</b>
-<blockquote>A data class used to store line information for the block frame
-code. Each line has a list of children (though the frames are linked together
-across lines to maintain the sibling list for nsIFrame::FirstChild) and
-some other state used to assist in incremental reflow.</blockquote>
-<b>nsLineLayout</b>
-<blockquote>This class is the line layout engine. Its a passive entity
-in the sense that its the responsibility of the block/inline code to use
-the class (this is done so that the line layout engine doesn't have to
-manage child frame lists so that both nsBlockFrame and nsInlineFrame can
-use the class).</blockquote>
-<b>nsTextRun</b>
-<blockquote>This is a data class used to store text run information. Text
-runs are <i>logically</i> contiguous runs of text (they may or may not
-be structurally contiguous). The block frame stores a pointer to a list
-of nsTextRun's and during line layout provides the list to the nsLineLayout
-engine so that when text is reflowed the text layout code (nsTextFrame)
-can find related text to properly handle word breaking.</blockquote>
-
-<h3>
-<u>Frame construction methods</u></h3>
-When the blocks child list is modified (AppendFrames, InsertFrames, RemoveFrame)
-the block code updates its nsLineBox list. Since each nsLineBox is typed
-(some are marked "inline" and some are marked "block"), the update logic
-maintains the invariant of "one block frame per block line".
-<p>When structural changes are made to the blocks children (append/insert/remove)
-the block code updates the line's and then marks the affected lines "dirty"
-(each nsLineBox has a dirty bit). After the structural changes are finished
-then the block will generate an incremental reflow command of type "ReflowDirty".
-<h3>
-<u>Line Layout</u></h3>
-Line layout consists of the placement of inline elements on a line until
-there is no more room on the line. At that point the line is "broken" and
-continued on the next line. This process continues until all inline elements
-have been exhausted. The block code maintains a list of "nsLineBox"'s to
-facilitate this. These are used instead of frames because they use less
-memory and because it allows the block to directly control their behavior.
-<p>The helper class nsLineLayout provides the majority of the line layout
-behavior needed by the block.
-<p>The block does keep "text-run" information around for the nsLineLayout
-logic to use during reflow. Text runs keep track of logically adjacent
-pieces of text within a block. This information is essential for properly
-computing line and word breaking. Why? Well, because in html you can write
-something like this:
-<p>&nbsp; &lt;p>I &lt;b>W&lt;/b>as thinking one day&lt;/p>
-<p>Notice that the word "Was" is composed of two pieces of text, and that
-they do <i>not</i> have the same parent (content or frame). To properly
-reflow this and not break the word prematurely after the "W", the text-run
-information is used by the text frame code to "look ahead" and prevent
-premature breaking.
-<p>Lines also keep track of the type of "break" that occurred on the line.
-This is used, for example, to support html's "&lt;br clear=left>" behavior.
-<h3>
-<u>Float Management</u></h3>
-Since child block elements are containing blocks for floats, the only
-place where a block frame will see a float is as part of an inline line.
-Consequently, the nsLineBox will only keep track of floats on inline
-lines (saving storage for block lines).
-<p>The nsLineLayout class and the block frame cooperate in the management
-of floats. Since the frame construction code leaves a "placeholder" frame
-in-flow where the float was found, when nsLineLayout reflows a placeholder
-frame it knows to inform the block about it. That triggers the blocks "AddFloat"
-logic which then determines where the float should be placed (on the
-current line or below the current line).
-<p>The block frame uses the space manager to manage the effects of floats,
-namely the consumption of available space. For example, for a left aligned
-floating element, the inline elements must be placed to the right of the
-float. To simplify this process, the spacemanager is used to keep track
-of available and busy space. Floats when placed mark space as busy and
-the spacemanager will them compute the available space. Most of this logic
-is handled by the nsBlockReflowState which uses a helper class, nsBlockBandData,
-in concert with the space manager, to do the available space computations.
-<h3>
-<u>Child Block Placement</u></h3>
-Child block reflow is done primarily by using the nsBlockReflowContext
-code. However, a key detail worth mentioning here is how margins are handled.
-When the nsHTMLReflowState was created, we placed into it the logic for
-computing margins, border and padding (among other things). Unfortunately,
-given the css rules for sibling and generational margin collapsing, the
-nsHTMLReflowState is unable to properly compute top and bottom margins.
-Hence, the block frame and the nsBlockReflowContext code perform that function.
-At the time that the nsBlockReflowContext was designed and implemented
-we thought that it could compute the top-margin itself and then proceed
-to place the child block element. However, that turned out to be wrong
-(oh well) because the correct available space isn't known until <i>after</i>
-the top margin is computed. Hence, there is some unfortunate duplication
-of reflow state calculations present in the block frame code.
-<h3>
-<u>Bullets</u></h3>
-Another type of block frame is the "display: list-item". List-items use
-nsBulletFrame's to manage bullet reflow. However, the block is responsible
-for bullet placement. In most situations, the nsLineLayout class is used
-to do the placement. However, if the first effective child of the block
-is another block, then the block has to do the placement itself.
-<h3>
-<u>Blank lines</u></h3>
-Because our content model contains as much of the original source documents
-content as possible, we end up with a lot of white space that ends up being
-compressed into nothingness. This white space ends up impacting this logic
-in several ways. For example:
-<p>&nbsp; &lt;div>
-<br>&nbsp;&nbsp; &lt;p>abc&lt;/p>
-<br>&nbsp;&nbsp; &lt;p>def&lt;/p>
-<br>&nbsp; &lt;/div>
-<p>In the content model for the above html, there is white space between
-the various block elements (some after the &lt;div>, some after the first
-&lt;/p>, again after the second &lt;/p>).
-<p>For css margin collapsing to work properly, each of those instances
-of white space has to behave as if they didn't exist. Consequently, there
-is special logic in the inline line reflow code, and in the nsBlockReflowContext
-code and in the GetTopBlockChild method, to basically ignore such lines.
-<h3>
-<u>First-letter style</u></h3>
-The block contributes, in a small way, to first-letter style reflow. The
-frame construction code is responsible for creating the list of child frames
-for all frames, including the block. It manages the creation of letter-frames,
-where appropriate, so that all the block has to do is reflow them almost
-normally like other inline frames.
-<p>There are two things different that the block does:
-<p>It is responsible for calling nsLineLayout::SetFirstLetterStyleOK
-<br>It is responsible for continuing to place frames on a line, even after
-a frame has said "it can't fit". Normally during inline reflow, if a frame
-comes back and says it can't fit, the block will end the line, push all
-remaining frames to the next line and pick up the reflow from there after
-making sure the frame that didn't fit is continued. For letter-frames,
-this would result in the first-letter being on one line with the remaining
-text on subsequent lines. Hence, the block code handles this special case.
-<br>&nbsp;
-<h3>
-<u>First-line style</u></h3>
-First-line is handled entirely by the frame construction code.

-<h1>
-HTML Layout Internals</h1>
-
-<h2>
-Big picture</h2>
-An HTML document comes in from netlib into the HTML parser.&nbsp; The parser
-creates parser nodes and feeds them to the content sink.&nbsp; The content
-sink constructs a content model that represents the hierarchical structure
-of the document.&nbsp; As different sub-trees in the content model are
-fully available, the stylesheet processor iterates over them and creates
-the corresponding frame hierarchy.&nbsp; The frames recursively layout
-and render themselves.
-<p>The part that we are going to drill down into is the code in the block
-and inline frame classes.&nbsp; Block and inline are the two primary display
-types specified in CSS and are used in the layout of most of the HTML tags.&nbsp;
-The table related tags have their own display types like "table-cell",
-"table-row", etc. and their implementation is a separate topic in itself.
-<h2>
-Block and inline code</h2>
-The main classes involved in the layout of HTML documents are nsBlockFrame
-and nsInlineFrame, both of which inherit from nsHTMLContainerFrame (why?).&nbsp;
-These classes are persistent across reflows and are organized in a hierarchy
-to constitute the frame model of the Gecko system.&nbsp; The frame model
-is derived by applying style and presentation semantics to the content
-model.&nbsp; Each frame in the frame model has a one to one correspondence
-with a rectangular region on the presentation context (screen, printer,
-etc.) and contains the formatting information needed to render that rectangle.&nbsp;
-The block and inline frame classes implement the nsIFrame and nsIHTMLReflow
-interfaces.&nbsp; The nsIFrame interface contains methods for managing
-child frames and linkage with sibling frames, accessing the style context
-associated with the frame, painting the frame, and handling events that
-are passed in from the widget hierarchy.&nbsp; The nsIHTMLReflow interface
-inherits from the nsIReflow interface and adds methods related to word
-breaking and whitespace querying.&nbsp; The nsIReflow interface defines
-the Reflow() method that initiates the reflow process along with the WillReflow()
-and DidReflow() methods that get called before and after the reflow process
-respectively.&nbsp; nsReflowState and nsReflowMetrics are parameters to
-the templatized nsIReflow interface: the former is used to hold state during
-reflow of a frame and the latter is used to return the frame's desired
-size and alignment to the parent frame during the reflow process.
-<p>nsBlockReflowContext and nsBlockReflowState both hold state information
-during the reflow process.&nbsp; nsBlockReflowContext encapsulates the
-state and algorithm for reflowing child block frames.&nbsp; nsBlockReflowState
-contains state and methods used by a block frame to reflow itself.&nbsp;
-Both these classes are instantiated once per block frame.
-<p>The nsLineLayout class is the engine used by the block and inline frame
-classes to layout themselves on a line.&nbsp; Frames get passed in to the
-nsLineLayout class via the BeginSpan() and EndSpan() methods.&nbsp; Each
-span represents a run of frames with the same style data (???).&nbsp; Other
-methods exist on the nsLineLayout class to position and size the frames
-on the current line.
-<p>nsBlockBandData is the class used to manage the processing of the space-manager
-(nsSpaceManager) band data.&nbsp; It provides HTML/CSS specific semantics
-on top of the general space management facilities provided by nsSpaceManager.
-<p>nsSpaceManager is a class that is told about regions that reserve space
-and exposes methods to query for available space in a given band.
-<p>The nsLineBox class represents a horizontal line of frames and is singly
-linked to the next line box in the document.&nbsp; It is basically a container
-of a frame list that share the property of being on the same line in the
-formatted output of the document.
-<p>The nsTextRun class holds on to a list of frames containing pieces of
-text that form a logical text run.&nbsp; This is needed because a single
-text run can occur on leaves at many levels of the document's content tree.&nbsp;
-This class gives the text layout process an efficient way to get access
-to text runs and, so, determine where word breaks should occur.
-<h2>
-Questions</h2>
-What are anonymous blocks (nsBlockFrame.h)?
-<br>What is the difference between a span and a band (nsLineLayout)?
-<br>Why do nsBlockFrame and nsInlineFrame both inherit from nsHTMLContainerFrame?
-<h2>
-To Do</h2>
-
-<ol>
-<li>
-Provide more information about methods and state of each of the classes
-above.</li>
-
-<li>
-Give a description of how the above classes interact with each other as
-a simple HTML document is laid out.&nbsp; Then, add in different features
-to the HTML that exercise different areas of the code, like floats, anonymous
-blocks, etc.</li>

-<SectionHeading>Document Loading</SectionHeading>
-<Body>The basic flow of control is as follows: as the parser encounters tokens it notifies
-the content sink that a new node (or child node) is encountered. The content sink
-creates the appropriate type content object and inserts it into the content model.</Body>
-
-<Body>Whenever the content model changes the document's observers are notified. The presentation
-shell is one of the document observers. The presentation shell forwards the document
-change notification to the style set object</Body>
-
-<Body>The style set passes the notification to the frame construction code, the
-frame construction code creates new frames and inserts them into the frame model. The
-document is reflowed, and the formatted changes are displayed.

-
-<Body>All of the interface files are located in the mozilla/layout/base/public
-directory.</Body>
-
-<SectionHeading>Object Lifetimes</SectionHeading>
-<Body>Gecko supports multiple views of the same document. This means you can print the
-same document that you're viewing on the screen, and there's only one content
-model. Because there's just a single content model, each of the content objects
-is referenced counted. The document holds a reference to the root content object,
-and each content node holds a reference to its child content nodes.</Body>
-
-<Body>Each view of the document has a separate presentation shell, style manager,
-style set, and frame hierarchy. The presentation shell is the controlling point for
-the presentation of a document, and it holds a reference to the document object.</Body>
-
-<Body>Frames and views are not referenced counted. The lifetime of the frame hierarchy
-is bounded by the lifetime of the presentation shell which owns the frames. The
-lifetime of the view hierarchy is bounded by the lifetime of the view manager
-that owns the views.</Body>
-
-<SectionHeading><html:a name="Frames">Frames</html:a></SectionHeading>
-<Body>Each frame defines a particular set of formatting characteristics. Frames have
-the opportunity to:
-<Characteristics>
-<Characteristic>reflow (format) their child frames</Characteristic>
-<Characteristic>render their appearance</Characteristic>
-<Characteristic>handle mouse and keyboard events</Characteristic>
-<Characteristic>display a cursor</Characteristic>
-<Characteristic>have an associated view object</Characteristic>
-</Characteristics>
-</Body>
-
-<Body>Frames can have multiple child lists, the default unnamed child list
-(referred to as the principal child list) and additional named child lists.
-There is an ordering of frames within a child list, but no ordering
-between frames in different child lists of the same parent frame.</Body>
-
-<Body>The principal child list contains the flowed children, and the additional
-child lists are for out-of-flow frames like floated elements and absolutely
-positioned elements.</Body>
-
-<Body>Child frames are linked together in a singly linked list. Each frame
-defines its own local coordinate space. Frame bounding rects are in twips,
-and the origin is relative to the upper-left corner of its parent frame.
-The bounding rect includes the content area, borders, and padding.</Body>
-
-<SectionHeading><html:a name="FrameConstruction">Frame Construction</html:a></SectionHeading>
-<Body>The frame construction process begins with a notification that content
-has been added or removed or that style has changed.</Body>
-
-<Body>The first step is to resolve style information for the content element.
-This process creates a style context that is stored in the frame (see
-nsIStyleContext).</Body>
-
-<Body>Once style is resolved construction rules are used to decide the type of
-frame to create. First we look at the element's tag and special case some
-things like IMG elements. If we don't create a frame that way, then we use
-the 'display' property to dictate what type of frame to create. Typically
-it's a block or inline frame.</Body>
-
-<Body>For a 'display' value of 'none' no frame is created. For elements that are
-out of the flow (for example, a floated element or an absolutely positioned
-element), a placeholder frame is also created. The placeholder frame is inserted
-into the flow exactly where the out-of-flow frame would have been inserted.
-The out-of-flow frame is then inserted as a child of its containing block in
-one of the additional child lists. Floated frames are inserted into the
-"Float-list" and absolutely positioned frames are inserted into the
-"Absolute-list".</Body>
-
-<SectionHeading>Frame Manager</SectionHeading>
-<Body>The frame manager is owned by the presentation shell and used by both the
-presentation shell and the frame construction code. It serves two main
-purposes:
-<Purposes>
-<Purpose>provides a service for mapping from content object to frame and from out-of-flow
-frame to placeholder frame</Purpose>
-<Purpose>coordinates structural modifications to the frame model</Purpose>
-</Purposes>
-</Body>
-
-<Body>In many places in the frame code we need to find the frame associated with
-a particular content object. In order to quickly implement this operation we
-maintain a mapping from content objects to frames. The frame construction adds
-and removes entries from the map as frames are created and destroyed.</Body>
-
-<Body>When creating new frames and removing existing frames, the frame construction
-code doesn't directly modify the frame hierarchy. Instead if informs the frame
-manager and has it coordinate the request. If the frame model lock is available,
-the change is processed immediately; otherwise, the request is queued and
-processed later.</Body>
-
-<Body>The frame manager also coordinates processing of replaced elements that can't
-be rendered (for example, an IMG or OBJECT element), and it allows client to
-register to be notified when a particular frame is being destroyed. This is
-needed because frames are not reference counted. It's used by the event manager
-and other clients to ensure that any outstanding references to the frame are
-cleaned up.</Body>
-
-<SectionHeading><html:a name="Reflow">Reflow</html:a> Process</SectionHeading>
-<Note>The fact that are two reflow interfaces reflects an early
-goal of having core layout and HTML specific layout. The core reflow process would
-be the same for all frames, and each class of formatting objects (for
-example, CSS and DSSSL) would have their own reflow additions.</Note>
-
-<Body>The reflow process is a top-down protocol where a frame is given some
-available space and asked to reflow its child frames and return a desired
-size.</Body>
-
-<Body>The reflow process is not part of the nsIFrame interface. The generic reflow
-interface is defined in the nsIFrameReflow interface, and the HTML/CSS specific
-reflow interface is defined in the nsIHTMLReflow interface.</Body>
-
-<Body>An important part of the reflow process is the calculation of the computed
-values for the CSS properties. This includes things like 'width', 'height',
-and 'margin', and involves calculation of the containing block width and height
-and percentage based values and properties whose value is inherited.</Body>
-
-<Body>This process is encapsulated in the HTML specific reflow state struct
-(struct nsHTMLReflowState) that is passed in as part of reflow. The reflow
-states are linked together with the reflow state for a child frame pointing
-to its parent frame's reflow state. This allows us to walk up the reflow state
-structures and calculate containing block width and height and percentage
-based values.</Body>
-
-<Body>In addition to the computed values for the CSS box model properties, the
-following items are also included:
-<Items>
-<Item>reflow reason that indicates why the frame is being reflowed</Item>
-<Item>a rendering context that can be used to measure text</Item>
-<Item>reflow command (only used for incremental reflow)</Item>
-<Item>space manager</Item>
-</Items>
-</Body>
-
-<Body>The most common reflow reasons are 'eReflowReason_Resize' (the viewport
-has changed size) and 'eReflowReason_Incremental' (processing of an incremental
-reflow command).</Body>
-
-<Body>Reflow commands (see nsHTMLReflowCommand in mozilla/layout/html/base/src) are used
-to kick off an incremental reflow. They're generated either by the style system
-(in response to a style change) or by a frame itself (for example, if a frame has
-dirty child frames that need to be reflowed it will generate a reflow command).</Body>
-

-<h1>
-<u>Line Layout</u></h1>
-Line layout is the process of placing inline frames horizontally (left
-to right or right to left depending on the CSS direction property value).
-An attempt is made to describe how it works.
-<p>nsLineLayout is the class that provides support for line layout. The
-container frames nsBlockFrame and nsInlineFrame use nsLineLayout to perform
-line layout and span layout. Span layout is a subset of line layout used
-for inline container classes - for example, the HTML "B" element). Because
-of spans, nsLineLayout handles the nested nature of line layout.
-<p>Line layout as a process contains the following steps:
-<ol>
-<li>
-Initialize the nsLineLayout object (done in nsBlockFrame). This prepares
-the line layout engine for reflow by initializing its internal data structures.</li>
-
-<br>&nbsp;
-<li>
-Reflowing of inline frames. The block code uses nsLineLayout's <b>ReflowFrame</b>
-method to reflow each inline frame in a line. This continues until the
-line runs out of room or the block runs out of frames. The block may be
-reflowing a span (an instance of nsInlineFrame) which will recursively
-use nsLineLayout for reflow and placement of the frames in the span.</li>
-
-<p><br>Note that the container frames (nsBlockFrame/nsInlineFrame) call
-nsLineLayout's ReflowFrame method instead of having the line layout code
-process a list of children. This is done so that the container frames can
-handle the issues of "pushing" and "pulling" of frames across continuations.
-Because block and inline maintain different data structures for their child
-lists, and because we don't want to mandate a common base class, the line
-layout code doesn't control the "outer loop" of frame reflow.
-<br>&nbsp;
-<li>
-Finish line layout by vertically aligning the frames, horizontally aligning
-the frames and relatively positioning the frames on the line.</li>
-</ol>
-nsLineLayout is also used by nsBlockFrame to construct text-run information;
-this process is independent of normal line layout is pretty much a hack.
-<p>When frames are reflowed they return a reflow status. During line layout,
-there are several additions to the basic reflow status used by most frames:
-<ul>
-<li>
-NS_FRAME_COMPLETE - this is a normal reflow status and indicates that the
-frame is complete and doesn't need to be continued.</li>
-
-<li>
-NS_FRAME_NOT_COMPLETE - this is another normal reflow status and indicates
-that the frame is not complete and will need a continuation frame created
-for it (if it doesn't already have one).</li>
-
-<li>
-NS_INLINE_BREAK - some kind of break has been requested. Breaks types include
-simple line breaks (like the BR tag in html sometime does) and more complex
-breaks like page breaks, float breaks, etc. Currently, we only support
-line breaks, and float clearing breaks. Breaks can occur before the frame
-(NS_INLINE_IS_BREAK_BEFORE) or after the frame (NS_INLINE_IS_BREAK_AFTER)</li>
-</ul>
-The handling of the reflow status is done by the container frame using
-nsLineLayout.
-<h3>
-<u>Line Breaking</u></h3>
-Another aspect of nsLineLayout is that it supports line breaking. At the
-highest level, line breaking consists of identifying where it is appropriate
-to break a line that doesn't fit in the available horizontal space. At
-a lower level, some frames are breakable (e.g. text) and some frames are
-not (e.g. images).
-<p>In order to break text properly, some out-of-band information is needed
-by the text frame code (nsTextFrame). In particular, because a "word" (a
-non-breakable unit of text) may span several frames (for example: <b>"&lt;B>H&lt;/B>ello
-there"</b> is breakable after the <b>"o"</b> in "<b>ello</b>" but not after
-the <b>"H"</b>), text-run information is used to allow the text frame to
-find adjacent text and look at them to determine where the next breakable
-point is. nsLineLayout supports this by keeping track of the text-runs
-as well as both storing and interrogating "word" state.
-<h3>
-<u>White-space</u></h3>
-To support the white-space property, the line layout logic keeps track
-of the presence of white-space in the line as it told to reflow each inline
-frame. This allows for the compression of leading whitespace and the compression
-of adjacent whitespace that is in separate inline elements.
-<p>As a post-processing step, the TrimTrailingWhiteSpace logic is used
-to remove those pesky pices of white-space that end up being placed at
-the end of a line, that shouldn't really be seen.
-<p>To support pre-formatted text that contains tab characters, the line
-layout class keeps track of the current column on behalf of the text frame
-code.
-<h3>
-<u>Vertical Alignment</u></h3>
-Vertical alignment is peformed as a two and a half pass process. The first
-pass is done during nsInlineFrame reflow: the child frames of the nsInlineFrame
-are vertically aligned as best as can be done at the time. There are certain
-values for the vertical-align property that require the alignment be done
-after the lines entire height is known; those frames are placed during
-the last half pass.
-<p>The second pass is done by the block frame when all of the frames for
-a line are known. This is where the final height of the line
-<br>(not the line-height property) is known and where the final half pass
-can be done to place all of the top and bottom aligned elements.
-<br>&nbsp;
-<h3>
-<u>Horizontal Alignment</u></h3>
-After all frames on a line have been placed vertically, the block code
-will use nsLineLayout to perform horizontal alignment within the extra
-space.

-HTML</H2>
-This documents describes the complete handling of HTML in magellan. The
-document covers the parsing process - how HTML is lexically analysized
-and then interprted. After the parsing process is discussed we give a detailed
-analysis of each HTML tag and the attributes that are supported, the values
-for the attributes and how the tag is treated by magellan.
-<H2>
-Parsing</H2>
-HTML is tokenized by an HTML scanner. The scanner is fed unicode data to
-parse. Stream converters are used to translate from various encodings to
-unicode. The scanner separates the input stream into tokens which consist
-of:
-<UL>
-<LI>
-text</LI>
-
-<LI>
-tags</LI>
-
-<LI>
-entities</LI>
-
-<LI>
-script-entities</LI>
-
-<LI>
-comments</LI>
-
-<LI>
-conditional comments</LI>
-</UL>
-The HTML parsing engine uses the HTML scanner for lexical anlaysis. The
-parsing engine operates by attacking the input stream in a set of well
-defined steps:
-<UL>
-<LI>
-The parser processes the head portion of the document first, without emitting
-any output. This is done to discover a few special features of html:</LI>
-
-<UL>
-<LI>
-The parser processes META tags looking for META TARGET</LI>
-
-<LI>
-The parser processes META tags looking for META tags which affect the character
-set. Nav4 handles the very first character set defining meta tag (all others
-are ingored) by reloading the document with the proper character conversion
-module inserted into the stream pipeline.</LI>
-</UL>
-
-<LI>
-After the head portion is processed the parser then proceeds to process
-the body of the document</LI>
-</UL>
-
-<H3>
-Tag Processing</H3>
-Tags are processed by the parser by locating a <B>"tag handler"</B> for
-the tag. The HTML parser serves as the tag handler for all of the builtin
-tags documented below. Tag attribute handling is done during translation
-of tags into content. This mapping translates the tag attributes into content
-data and into style data. The translation to style data is documented below
-by indicating the mapping from tag attributes to their CSS1 (plus extensions)
-equivalents.
-<H3>
-Special Hacks</H3>
-The following list describes hacks added to the magellan parsing engine
-to deal with navigator compatability. These are just the parser hacks,
-not the layout or presentation hacks. Most hacks are intriduced for HTML
-syntax error recovering. HTML doesn't specify much how to handle those
-error conditions. Netscape has made big effort to render pages with non-prefect
-HTML. For many reasons, new browsers need to keep compatible in thsi area.
-<UL>
-<LI>
-Entities can be used as escape in quoted string. For value string in name-value
-pair,&nbsp; see <A HREF="../testhtml/quote001.html">compatibility test
-quote001.html</A>. Test line 70 shows that an entity quote at the begining
-means the value is NOT quoted. Test line 90 shows that if the value is
-started with a quote, then an entity quote does NOT terminate the value
-string.</LI>
-
-<LI>
-Wrapping tags are special tags such as title, textarea, server, script,
-style, and etc.. The comment in ns\lib\libparse\pa_parse.c says:</LI>
-
-<BR>&nbsp; /*
-<BR>&nbsp;&nbsp; * These tags are special in that, after opening one of
-them, all other tags are ignored until the matching
-<BR>&nbsp;&nbsp; * closing tag.
-<BR>&nbsp;&nbsp; */
-<BR>During the searching of an end tag, comments and quoted strings are
-observed. see <A HREF="../testhtml/title01.html">compatibility test title01.html</A>.
-6.0 handles coments now, need to add quoeted string.
-<LI>
-If a &lt;tr> or &lt;td> tag is seen outside any &lt;table> scope, it is
-ignored. see <A HREF="../testhtml/table110.htm">compatibility test table110.htm</A>.</LI>
-
-<LI>
-<FONT COLOR="#000000">In case of table in table but not in cell, table
-tags before the last table tag are ignored. We found this problem in some
-Netscape public pages, see bug #85118. For example, &lt;table> &lt;table

-will be displayed with border.&nbsp;</FONT> <A HREF="../testhtml/table201.html">compatibility
-test table201.html</A>. There table and tr tags are buffered for this recovery.
-When a TD or CAPTION tag is open, the buffer is flushed out, because we
-cannot buffer contents of TD or CAPTION for performance and memory constrains.
-They are subdoc's and can be very big. If we see a &lt;table> outside cell
-after previous table is flushed out, the new &lt;table> tag is ignored.
-Nav4.0 can discard previous table in such case. <A HREF="../testhtml/tableall.html">tableall.html

-Caption is not a commonly used feature. In Nav4.0, captions can be anywhere.
-For Captions outside cells, the first one takes effect. For captions inside
-cells, the last one takes effect, and they also close TD and TR. In 6.0,
-caption is limited to the standard position: after &lt;table>. Captions

-defines the number of columns to layout in (like MULTICOL). The open tag
-pushes an alignment on the alignment stack (if COLS > 1 then it pretends
-to be a MULTICOL tag). The close tag pops an aligment from the alignment
-stack.
-<BR>Attributes:

-</UL>
-<B>H1-H6</B>
-<UL>Closes the paragraph. The open tag does a hard line break and pushes
-a style item which enables bold and disables fixed and italic. The close
-tag always pops the top item from the style stack. It also does a hard
-line break. If the <B>ALIGN</B> attribute is present then the open tag
-pushes an alignment on the alignment stack. The close tag will look at
-the top of the alignment stack and if its a header of any kind (H1 through
-H6) then the alignment is popped. In either case the close tag also does
-a conditional soft line break (this happens before the hard line break).
-<BR>Attributes:
-<UL><B>ALIGN</B>=divalign</UL>
-</UL>
-A note regarding closing paragraphs: Any time a close paragraph is done
-(for any tag) if the top of the alignment stack has a tag named "P" then
-a conditional soft line break is done and the alignment is popped.

-The code supports more attributes in the Table attribute handler than it

-border_left, border_right, border_bottom, border_style (defaults to outset;
-allows for outset/dotted/none/dashed/solid/double/groove/ridge/inset).</UL>
-<B>TR</B>
-<UL>Open TR automatically closes an open table row (and an open table cell
-if one is open). It also automatically closes a CAPTION tag.

-<B>TH, TD</B>
-<UL>If no table then the tag is ignored (open or close). If no row is currently
-opened or the current row is current done (because of a &lt;/TR> tag) then
-a new row is begun. Oddly enough the tag parameters for the row come from
-the TH/TD tag in this case. An open of either of these tags will automatically
-close the previous cell.

-<B>CAPTION</B>
-<UL>An open caption tag will automatically close an open table row (and
-an open cell).
-<BR>Attributes:
-<UL><B>ALIGN</B>=bottom</UL>
-The code sets the vertical alignment to top w/o providing a mechanism for
-the user to set it (there is no VALIGN attribute).</UL>
-<B>MULTICOL</B>
-<UL>The open tag does a hard line break. The close tag checks to see if
-the state machine has an open multicol and if it does then it does a conditional
-soft line break and then continues to break until both margins are cleared
-of floating elements. It recomputes the margins based on the list indenting
-level (?). After the synthetic table is output the close tag does a hard
-line break.
-
-<P>This tag will treat the input as source for a table with one row and
-COLS columns. The data is laid out using the width divided by the number
-of columns. After the total height is known, the content is partitioned
-as evenly as possible between the columns in the table.
-<BR>Attributes:

-<HR ALIGN=LEFT WIDTH="50%"></H3>
-<B>BLOCKQUOTE</B>
-<UL>Closes the paragraph. The open tag does a hard line break. A list with
-the empty-bullet style is pushed on the list stack (unless TYPE=cite/jwz
-then a styled list is pushed). The close tag pops any list and does a hard
-line break.
-<BR>Attributes:

-<B>UL, OL, MENU, DIR</B>
-<UL>For top-level lists (lists not in lists) a hard break is done on the
-open tag, otherwise a conditional-soft-break is done. Tag always does a
-close paragrah. The close tag does a conditional soft line break when nested;
-when not nested the close tag does a hard line break (even if no list is
-open). The open tag pushes the list on the list stack. The close tag pops
-any list off the list stack.

-The magellan html parser allows the full set of list item styles from the
-OL/DL tag instead of just the limited set that nav4 allows.</UL>
-<B>DD</B>
-<UL>Closes the paragraph. Close tags are ignored (except for closing the
-paragraph). DD outside a DL just advances the X coordinate of layout by
-a small constant. DD inside a DL does a conditional soft line break and
-other margin crud.
-<BR>Attributes: none.</UL>
-<B>DT</B>
-<UL>Closes the paragraph (open or close). Close tags are otherwise ignored.
-Does a conditional soft line break. Moves the X layout coordinate to the

-<UL>Open anchors push a style on the style stack if the anchor has an <B>HREF</B>.
-Close anchors pop as many styles off the top of the style stack that are
-anchor tags (anchor tags don't nest in other words). In addition, any styles

-<BR>Attributes: none</UL>
-<B>SUP, SUB</B>
-<UL>The open tag pushes a font size descrease on the style stack. The close
-tag always pops the top of the style stack. The open and close tag impacts
-the baselineThe only difference between SUP and SUB is how they impact
-the baseline. Note that the baseline information is forgotten after a line

-A note regarding the style stack: The pop of the stack checks to see if
-the top of the stack is an ANCHOR tag. If it is not an anchor then the
-top item is unconditionally popped. If the top of the style stack is an
-anchor tag then the code searches for either the bottom of the stack or
-the first style stack entry not created by an anchor tag. If the entry
-is followed by another entry then the entry is removed from the stack (an
-out-of-order pop in other words). In this case the anchor style stack entry
-is left untouched.

-<B>text, entities</B>
-<UL>These are basic content objects that get fed directly to the output.
-In navigator the text is processed by doing line-breaking (entities have
-been converted to text already by the parser). The line-breaking is controlled
-by the margin settings and the list depth, the floating elements, the style
-attributes (font size, etc.), the preformatted flag, the no-break flag
-and so on.</UL>

-<B>PARAM</B>
-<UL>The param tag is supported when contained by the APPLET tag or the

-  <h2>Background</h2>
- The Layout module of Gecko has not been documented very well. This has lead 
-to some predictable problems: difficult maintenance, hard to get new people 
-involved in the module, problems assessing the risk of changes, hard to know 
-where bugs are likely to be in the source. &nbsp;One extreme result of the 
-lack of comprehensive has been an urge to rewrite some of the more impenetrable 
-parts of the layout component, the block and Line Layout areas. &nbsp;Rather 
-than throwing it all away and rewriting it, we have decided to put significant 
-effort into thoroughly documenting what we already have. this effort will 
-help us to understand what parts of the system we want to keep as-is, incrementally 
-revise, or wholesale rewrite. Additionally, we will make the code base more 
-accessible to new (and not-so-new) engineers.<br>
- <br>
- 
-  <h2>Strategy:</h2>
- Documenting all of Block and Line layout is a large task, so it will be
-divided up among knowledgeable and interested engineers. Progress will be
-tracked in bugzilla <a href="http://bugzilla.mozilla.org/show_bug.cgi?id=115310">
- bug 115310</a>
- . &nbsp;This document lays out the basic documentation scope and formatting 
-so that all of the individual contributions can be combined into a relatively 
-cohesive unit of linked documents. <br>
- <br>
- 
-  <h2>Scope:</h2>
- The documentation will generally cover two levels of detail. There is room 
-for deviation from this as needed, but generally a High Level Design document 
-and a Detailed Design document will provide the necessary level of detail 
-for those trying to understand the system as a whole, and those trying to 
-get into the code.<br>
- <br>
- 
-  <h3>High Level Designs</h3>
- High level designs provided an overview of the system being documented.
-The general concept of the component is described, and the classes involved
-are described briefly (no details of the class implementations). &nbsp;In
-some cases the high level design vocabulary consists of other components
-and not classes. &nbsp;The important thing is to describe the interactions
-between the classes and/or components such that the reader gets an understanding 
-of which pieces talk to which other pieces, what kinds of data are shared 
-by various components or classes, how the data is modified and by whom, beginning
-states and end states of a process, and external constraints or inputs into
-the system begin described. <br>
- <br>
- A fundamental piece of the high-level design is the<b> data model</b>. This 
-is generally a graphical representation of the classes or components involved 
-in the system, showing the relationships between them in terms of has-a,
-is-a, uses, owns, etc. the specific representation is not as important as
-the content of the representation. For example, using UML or Booch notation
-is fine, as is an ad-hoc diagram that shows the same types of information.<br>
- <br>
- Another important piece of the high-level design is a set of <b>use-cases</b>
-  that describe specific interaction that result from specific events in
-the system. For example, we might want to show specifically what happens
-when an attribute is changed on an element via the DOM. Use cases differ
-from data models in that they show specific instances of objects or components, 
-actual data values where interesting or important, and often give a glimpse 
-into the algorithms employed. All of the components or objects in the use 
-cases must be documented in the data model.<br>
- <b><br>
- State Transition Diagrams</b> may be important to some systems, and they 
-should be documented in the high-level design as well. These should be described 
-in terms of the abstract states that the system may be in, not in terms of 
-how the state-machine is actually implemented.<br>
- <br>
- The high-level documents provide an overview of the components and classes 
-that make up a system. It can be used as a road map to the related detailed 
-design documents for the components and classes involved in the system. thus, 
-the classes, components, and algorithms referenced in the high-level design
-document should be linked to the detailed design documents that correspond. 
-This link generally occurs at the first reference to the class or component, 
-but it can be provided in other contexts as well, for convenience to the reader.
-&nbsp;Missing or invalid links are considered errors in the high-level design.
-  <br>
- &nbsp;&nbsp; <br>
- 
-  <h3>Detailed Designs</h3>
- Detailed design documents provide specific information needed to implement 
-(or understand the implementation of) the components and classes described 
-in the high-level design. Users of the classes or components should also be
-able to understand from the detailed design just how the classes, components 
-and API's are to be used. Special performance characteristics of methods or
-interactions should be documented where pertinent.<br>
- <br>
- 
-  <h4>Public API</h4>
- The public API of the component or class being documented is essential to 
-the detailed design. Each publicly accessible interface, method and data member
-must be documented. Ideally this information is contained in the implementation 
-files for a class, interface or component. If this is the case, the actual 
-IDL or class header file can be used as the documentation for the public API.
-This should be done as a link or embedded document to avoid the perpetual 
-need to keep the document up to date with the source file. &nbsp;Specific 
-items that are important to the description of the publicly available aspects 
-of the component, class, or interface include:<br>
- 
-  <ul>
-   <li>entry-point semantics: what does the method do, or what does the data 
-member mean? Is the universe of expected clients limited or open (e.g.. who 
-can call it)?<br>
-   </li>
-   <li>preconditions: what are the legal states for the instance to be in 
-before the entry point is called? what are the legal values for the arguments? 
-what are the required states for the objects or components used in the entry-point?</li>
-   <li>postconditions: what is guaranteed when the entry-point is returned
-from? what return values are legal? what is the status of the output arguments 
-for various return states?</li>
-   <li>special performance characteristics: if there are special concerns 
-about performance of the method, explain them. for example, is the method 
-O(n^2)? Is there considerable memory required? Is the method recursive?</li>
- 
-  </ul>
- Beyond the public interfaces, the private and protected methods need to
-be documented as well. For protected methods and members, the expectations
-of the subclasses must be made clear (e.g.. should the subclass call the
-base class method? if so, when?) &nbsp;As with the public methods, the semantics, 
-preconditions, postconditions, and special performance considerations should 
-be described. Again, this may be by direct inclusion of the source code files 
-where appropriate.<br>
- <br>
- 
-  <h4>Algorithms</h4>
- There is often a need to document specific algorithms used in methods and 
-functions. &nbsp;Generally, it is not a good idea to include this sort of 
-information in the source files, so they must be described fully in the detailed 
-design document. &nbsp;The extent of this information varies wildly from one
-design to another. &nbsp;Be sure to include an Algorithms section to the
-document when there are interesting or critical algorithms that the classes 
-or components employ. &nbsp;Spell out the algorithms in as much detail as 
-possible using pseudo-code or diagrams. Ideally, it should be possible to 
-implement the algorithm from the information in the design.<br>
- <br>
- <br>
- Algorithms that involve several different components or object instances 
-require special attention. These algorithms tend to be more complex and more 
-difficult to completely specify. &nbsp;Start out by referring to the related 
-use cases in the high level design, and then drill down into the responsibilities 
-and requirements of the individual instances involved. &nbsp;Here, diagrams 
-and pseudo-code are indispensable in communicating how the algorithm is carried 
-out across the system.<br>
- 
-  <h4></h4>
-  <h4> Tech Notes</h4>
-The end of the detailed design document should contain a list of links to
-Tech Notes. These will vary in depth and scope, but generally they provide
-information geared toward helping developers work on the system. &nbsp;Tech
-Notes might contain information about &nbsp;how code has been modified, how
-a new feature was added, how to debug a certain class of problem, how to
-use built-in debugging r logging facilities, or how to maintain or extend
-unit tests. &nbsp;The Tech Notes should be stored in a publibly accessable
-location, as a comment or attachment in a bugzilla bug, for example. &nbsp;The
-text that holds the link should be descriptive of what the Tech Note addresses.<br>

-<h1>Table Regression Tests</h1>
-<h6>Bernd Mielke</h6>
-<h2>About This Document</h2>
-<p>
-This document describes my guerilla approach to successfully  running the table layout regression tests. It should encourage more people to run those tests.
-
-<h2>Subject Overview</h2>
-<p>
-The table element and its children are one of the major layout components that can create some structure on the screen. They are widely (ab)used  by page authors. Every small change in the table code can generate a bunch of bugzilla entries and a lot of seemingly unrelated dupes. With the high frequency of checkins in to the source tree  it is difficult and time consuming to track the regression down to a single checkin. The risk of becoming very infamous can be reduced by running the layout regression tests.
-
-<h2>Prerequisites</h2>
-<p>
-In order to run these tests, you will need to have:
-<ol>
-<li>a debug build with a working viewer, an optimized build will not work!
-<li>a mozilla tree with the testfiles at <code>%MOZ_SRC%/layout/html/tests</code>,
-<li> <code>DISABLE_TESTS</code> should not be defined,
-<li>patience and time.
-</ol>
-
-<h2>Test Runs</h2>
-
-<ul>
-<li>Go to the <code>%MOZ_SRC%/layout/html/tests/block</code>  directory.
-<li> Avoid the nasty assertions to pop up by <code>set XPCOM_DEBUG_BREAK=warn</code>, the world would be a much better place if we could <a href="http://bugzilla.mozilla.org/show_bug.cgi?id=152015">first fix those assertions</a>.
-<li>The following shell scripts need a <code>sh</code> before the command under WinXX.
-<li>Execute  <code>rtest.sh baseline</code>
-<li>Execute  <code>rtest.sh verify&gt;outputfile.txt</code>
-<li>Make a note which tests have failed (these are  false positives. If you are in bad mood file a bug against Chris Waterson about them)
-<li>you can grep the failures by:<br>
-<code>grep 'rgd failed' &lt;outputfile.txt &gt;false_positive.txt</code> 
-<li> Make a copy of <code>gklayout.dll</code> and <code>gkcontent.dll</code> in the <code>dist</code> directory. If you would like to switch back, you will need them.
-<li>Make your changes to the source, compile and install.
-<li>execute in the <code>layout/html/tests/block</code>  directory <code>rtest.sh verify &gt;regression.txt</code>
-<li>Check how many tests have failed and analyse your results:
-<ul>
-<li>If the regression tests have failed at the same place as the previous diagnosted false positives =&gt; ignore
-<ol>
-<li>copy  <code>rtest.sh</code>  to <code>my_rtest.sh</code> 
-<li>create a new directory <code>my_files</code>. 
-<li>create in this diretory a file <code>file_list.txt</code>, where you put the url's of your remaining test failures
-<li>change <code>my_rtest.sh</code> to use only directory <code>my_files</code>
-<li>go back to the original gklayout.dll and gkcontent.dll and repeat the regression test procedure on a much smaller set now.
-</ol>
-<li>Try to figure out what the other regressions are: Are they
-     improving the picture or are they regressions?
-<li>Note the difficult to explain testfailures.
-</ul>
-<li> Change the source if necessary until the regression tests indicate that your patch does not hork the block and table layout
-<li> Submit your patch and lists the remaining differences in the bug
-</ul>
-
-<p>Be prepared to cycle.
-
-<h2>How the layout regression tests work</h2>
-
-<p>First the URL's to test are red from <code>file_list.txt</code>.<p>
-<table><caption>snippet from file_list.txt</caption><tr><td>
-<pre>file:///s|/mozilla/layout/html/tests/table/dom/appendCells1.html
-file:///s|/mozilla/layout/html/tests/table/dom/appendCellsRebuild1.html
-file:///s|/mozilla/layout/html/tests/table/dom/appendCol1.html
-file:///s|/mozilla/layout/html/tests/table/dom/appendCol2.html
-file:///s|/mozilla/layout/html/tests/table/dom/appendColGroup1.html
-file:///s|/mozilla/layout/html/tests/table/dom/appendRowsExpand1.html</pre>
-</td></tr></table>
-<p>The regression tests compare the frame tree dumps recorded at two different times. The URL's to test are red from <code>file_list.txt</code>
-For every file in <code>file_list.txt</code>viewer takes the root frame and dumps the whole tree via 
-<a href="http://lxr.mozilla.org/seamonkey/search?string=nsFrame%3A%3ADumpRegression">
-nsFrame::DumpRegression</a>.
-<p>
- The frame tree dumps are  invoked by the <code>-o</code> switch to the <code>viewer</code> (see <a href="http://lxr.mozilla.org/seamonkey/ident?i=PrintHelpInfo">commandline arguments </a>). 
-When <code>-o</code> is specifed  together with a output directory for instance (<code>-o s:\mozilla\layout\html\tests\table\dom\</code>),  
-the frame trees are dumped to separate files in that directory for all URL's in <code>file_list.txt</code> (see: 
-<a href="http://lxr.mozilla.org/seamonkey/search?string=nsWebCrawler%3A%3ADumpRegression">
-nsWebCrawler::DumpRegressionData</a>) . 
-<p>Theire name is generated by replacing the old extension <code>.html</code> or <code>.xml</code> with <code>.rgd</code>.  For <code>file:///s|/mozilla/layout/html/tests/table/dom/appendCells1.html</code> a file <code>appendCells1.rgd</code> will be created in the <code>s:\mozilla\layout\html\tests\table\dom\</code> directory.
-
-<p>
- There is a special type of frame dumps - the printing regression tests, they are invoked by the <code>-Prt</code> command line argument to the <code>viewer</code> and include first a display then a frame dump taking into account the printer pages. A typical beginning of a dump (<code>*.rgd</code> file) looks like:<p>
-<pre class="screen">
-&lt;frame va="15022440" type="Viewport(-1)" state="270340" parent="0"&gt;

-  &lt;/stylecontext&gt;</pre>
-<p>The first run of the regression tests is started with the argument <code>baseline</code> and it creates the reference frame dumps. 
-<p>The <code>baseline</code> log will look like:

-<h2>Adding new regression tests</h2>
-<p>
-Once you have checked in the code:
-<ul>
-<li> please add your testcase for the bug to the regression tests.  
-<li>A testcase should only contain local files. 
-<li>Place the images in <code>table/images</code> (don't forget <code> cvs commit -kb </code>) 
-<li>and the testfile in the <code>table/bugs</code> directory. 
-<li>Update the <code>file_list<b>x</b>.txt</code> in order to include your file.
-</ul>
-<p>I would like to thank Chris Karnaze for his guidance and fantasai for his language support.
