intrinsic sizing of windows. (Unlike HTML and XML, we are no longer wrapped
in an area frame. We are instead wrapped in a box frame.)
Also included is a patch for the table code, since it crashes inside boxes
because of a bug in its incremental reflow code.
nsISpaceManager was touched to give it a GetIID method so that it could be
used with nsCOMPtrs.
