-
-B<Moz> comprises the routines needed to slap CodeWarrior around, force it
-to build a sequence of projects, report the results, and a few other things.
-This module should only contain functions that are generic to any build,

-=head2 Logging all the errors and warnings - C<OpenErrorLog($log_file)>, C<CloseErrorLog()>
-
-The warnings and errors generated in the course of building projects can be logged to a file.
-Tinderbox uses this facility to show why a remote build failed.
-
-Logging is off by default.
-  Start logging at any point in your build process with C<OpenErrorLog($log_file)>.
-  Stop with C<CloseErrorLog()>.
-  You never need to close the log explicitly, unless you want to just log a couple of projects in the middle of a big list.
-  C<CloseErrorLog()> is not exported by default.

-=head2 Stopping before it's too late - C<StopForErrors()>, C<DontStopForErrors()>
-
-When building a long list of projects, you decide whether to continue building subsequent projects when one fails.
-  By default, your build script will C<die> after the first project that generates an error while building.
-  Change this behavior with C<DontStopForErrors()>.
-  Re-enable it with C<StopForErrors()>.

-%   Lines which modify the default build settings. For the list of flags,
-%   see MozBuildFlags.pm. Examples are:
-%
-%    build       pull            0                    % don't pull

-%   Line containing the special 'buildfrom' flag, which specifies

-%   
-%    buildfrom   nglayout                % where to start the build
-%
-%   Lines which specify the location of the files used to store paths
-%   to the CodeWarrior IDE, and the MacCVS Pro session file. Note quoting

-%
-%    filepath   idepath         ::codewarrior.txt
-%    filepath   sessionpath     ":Some folder:MacCVS session path.txt"
-%
-%   Lines which modify the build settings like %main::DEBUG.

+// The icon decoder is a decoder specifically tailored for loading icons 
+// from the OS. We've defined our own little format to represent these icons
+// and this decoder takes that format and converts it into 24-bit RGB with alpha channel
+// support. It was modeled a bit off the PPM decoder.
+//
+// Assumptions about the decoder:
+// (1) We receive ALL of the data from the icon channel in one OnDataAvailable call. We don't
+//     support multiple ODA calls yet.
+// (2) the format of the incoming data is as follows:
+//     The first two bytes contain the width and the height of the icon. 
+//     Followed by 3 bytes per pixel for the color bitmap row after row. (for heigh * width * 3 bytes)
+//     Followed by bit mask data (used for transparency on the alpha channel).

+ * a little more data copying but is far easier to get right.)
+ *
+ * At any one time, the JPEG decompressor is either reading from the necko
+ * input buffer, which is volatile across top-level calls to the IJG library,
+ * or the "backtrack" buffer.  The backtrack buffer contains the remaining
+ * unconsumed data from the necko buffer after parsing was suspended due
+ * to insufficient data in some previous call to the IJG library.
+ *
+ * When suspending, the decompressor will back up to a convenient restart
+ * point (typically the start of the current MCU). The variables
+ * next_input_byte & bytes_in_buffer indicate where the restart point will be
+ * if the current call returns FALSE.  Data beyond this point must be
+ * rescanned after resumption, so it must be preserved in case the decompressor
+ * decides to backtrack.
+ *
+ * Returns:
+ *  TRUE if additional data is available, FALSE if no data present and
+ *   the JPEG library should therefore suspend processing of input stream
