*Revision 1.6  2006/04/07 02:35:42  ddiego
*initial checkin of merge from 0.6.9 dev branch.
*
*Revision 1.5.2.2  2006/02/16 04:49:57  ddiego
*minor fixes to vc80 projects and a bug fix in graphics kit for default font on XP.
*
*Revision 1.5.2.1  2005/11/04 17:56:17  ddiego
*fixed bugs in some win32 code to better handle unicode - ansi functionality.
*
*Revision 1.5  2005/07/09 23:06:01  ddiego
*added missing gtk files
*
*Revision 1.4  2005/01/02 03:04:26  ddiego
*merged over some of the changes from the dev branch because they're important resoource loading bug fixes. Also fixes a few other bugs as well.
*
*Revision 1.3.2.3  2005/04/13 01:08:49  iamfraggle
*Enable Unicode in CodeWarrior
*
*Revision 1.3.2.2  2005/02/16 05:09:34  ddiego
*bunch o bug fixes and enhancements to the property editor and treelist control.
*
*Revision 1.3.2.1  2004/12/19 04:05:05  ddiego
*made modifications to methods that return a handle type. Introduced
*a new typedef for handles, that is a pointer, as opposed to a 32bit int,
*which was causing a problem for 64bit compiles.
*
*Revision 1.3  2004/12/01 04:31:44  ddiego
*merged over devmain-0-6-6 code. Marcello did a kick ass job
*of fixing a nasty bug (1074768VCF application slows down modal dialogs.)
*that he found. Many, many thanks for this Marcello.
*
*Revision 1.2.2.16  2004/11/01 19:38:47  marcelloptr
*minor change
*
*Revision 1.2.2.15  2004/10/31 15:32:29  ddiego
*fixed a bug in the way Win32ControlContext::releaseHandle() worked that was causing a problem in Win32Font::getPointSize().
*
*Revision 1.2.2.14  2004/10/25 03:52:02  ddiego
*minor changes to osx checkin for win32
*
*Revision 1.2.2.13  2004/10/11 14:28:47  kiklop74
*First version of patch for BUG 1042623 - Incorect handling of DC in win32font
*
*Revision 1.2.2.12  2004/10/04 15:51:15  kiklop74
*Added explicit cast to avoid ambiquity on BCB6
*
*Revision 1.2.2.11  2004/09/21 23:41:25  ddiego
*made some big changes to how the base list, tree, text, table, and tab models are laid out. They are not just plain interfaces. The actual
*concrete implementations of them now derive from BOTH Model and the specific
*tree, table, etc model interface.
*Also made some fixes to the way the text input is handled for a text control.
*We now process on a character by character basis and modify the model one
*character at a time. Previously we were just using brute force and setting
*the whole models text. This is more efficent, though its also more complex.
*
*Revision 1.2.2.10  2004/09/01 03:50:39  ddiego
*fixed font drawing bug that tinkham pointed out.
*
*Revision 1.2.2.9  2004/08/31 08:55:58  marcelloptr

*Destructors were moved back to pbulic scope in case that was causing a bug.
*Moving them all(all teh component derived classes) to private scope causes
*a complete failure in hte VC6 compiler. Alas...
*So destructors are present, and modal dialogs can still be created on the
*stack, but almost any other component should be created on the heap, and
*gotten rid of via free() NOT using operator delete directly.
*also moved the vcs info to the end of the file for some of the headers
*This will be an ongoing process.
