/**
*CVS Log info
 *$Log$
 *Revision 1.4  2006/04/07 02:35:34  ddiego
 *initial checkin of merge from 0.6.9 dev branch.
 *
 *Revision 1.3.4.3  2006/01/14 21:49:21  ddiego
 *general osx checkin
 *
 *Revision 1.3.4.2  2005/11/27 23:55:45  ddiego
 *more osx updates.
 *
 *Revision 1.3.4.1  2005/11/10 02:02:38  ddiego
 *updated the osx build so that it
 *compiles again on xcode 1.5. this applies to the foundationkit and graphicskit.
 *
 *Revision 1.3  2004/12/01 04:31:41  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 1.2.2.1  2004/10/10 20:42:08  ddiego
 *osx updates
 *
 *Revision 1.2  2004/08/07 02:49:14  ddiego
 *merged in the devmain-0-6-5 branch to stable
 *
 *Revision 1.1.2.6  2004/06/06 07:05:32  marcelloptr
 *changed macros, text reformatting, copyright sections
 *
 *Revision 1.1.2.4  2004/05/03 03:44:53  ddiego
 *This checks in a bunch of changes to the FoundationKit for OSX
 *porting. The thread, mutex, semaphor, condition, and file peers
 *have all been implemented and tested. The file peer could be improved
 *and needs search functionality. The locale peer is only partially
 *complete, but the functions will return values. The unicode transition
 *is also finished and works OK now.
 *
 *Revision 1.1.2.3  2004/04/30 05:44:34  ddiego
 *added OSX changes for unicode migration
 *
 *Revision 1.4  2004/04/03 15:48:47  ddiego
 *Merged over code from the 0-6-3 branch.
 *
 *Revision 1.3.2.1  2004/02/21 03:27:09  ddiego
 *updates for OSX porting
 *
 *Revision 1.2  2003/08/09 02:56:46  ddiego
 *merge over from the devmain-0-6-1 branch
 *Changes
 *Features:
 *-Added additional implementation to better support the MVC architecture in
 *the VCF
 *
 *-Added a Document/View architecure that is similar to MFC's or NextSteps's
 *Doc/View architectures
 *
 *-Integrated the Anti Grain Graphics library into the GraphicsKit. There is
 *now basic support for it in terms of drawing vector shapes
 *(fills and strokes). Image support will come in the next release
 *
 *-Added several documented graphics tutorials
 *
 *Bugfixes:
 *
 *[ 775744 ] wrong buttons on a dialog
 *[ 585239 ] Painting weirdness in a modal dialog ?
 *[ 585238 ] Modal dialog which makes a modal Dialog
 *[ 509004 ] Opening a modal Dialog causes flicker
 *[ 524878 ] onDropped not called for MLTcontrol
 *
 *Plus an issue with some focus and getting the right popup window to activate
 *has also been fixed
 *
 *Revision 1.1.2.2  2003/06/23 23:16:55  ddiego
 *added some furtther implementation for the osx port
 *
 *Revision 1.1.2.1  2003/05/22 04:40:05  ddiego
 *removed the .cpp files in favor of .mm files to allow Objective-C++ compiling
 *
 *Revision 1.2  2003/05/17 20:37:34  ddiego
 *this is the checkin for the 0.6.1 release - represents the merge over from
 *the devmain-0-6-0 branch plus a few minor bug fixes
 *
 *Revision 1.1.2.1  2003/05/15 03:01:03  ddiego
 *added initial osx source( FoundationKit only),
 *plus some fixes to compile under GCC 3.x compilers
