*
*Revision 1.1.2.3  2004/07/30 17:30:05  kiklop74

*
*Revision 1.1.2.2  2004/04/29 04:10:27  marcelloptr

*Revision 1.14  2004/02/15 21:55:36  ddiego
*Added changes for vc7.1 compiler, many thanks to Raghavendra Chandrashekara for helping with this.
*
*Revision 1.13  2003/12/18 05:15:58  ddiego
*merge from devmain-0-6-2 branch into the stable branch
*
*Revision 1.12.2.2  2003/10/28 04:06:11  ddiego
*updated the GraphicsContext and ContextPeer classes to support
*slider control drawing. adjusted the Slider control accordingly.
*Also changed some of the GraphicsKit headers to conform to the
*current header style.
*
*Revision 1.12.2.1  2003/09/12 16:46:33  ddiego
*finished adding header changes to improve compile speed (at least
*with MS VC++) and to get rid of some of the clutter that the RTTI macros
*add.
*But Where'd the RTTI info go!?!?
*Have no fear it's still there! It is now located in three .inl files, one
*for each kit. Each kit will consolidate it's RTTI decls in the following
*files:
*FoundationKit:
*  vcf/include/FoundationKitRTTI.inl
*GraphicsKit:
*  vcf/include/GraphicsKitRTTI.inl
*ApplicationKit:
*  vcf/include/ApplicationKitRTTI.inl
*
*Please alter these files as neeccessary to add/subtract/alter the various
*RTTI info. Each kit is also responsible for registering any of the class
*in the ClassRegistry.
*A side effect of this is that I had to alter the memory allocation for the
*VC6 build for the Application it went from /Zm120 to /Zm150. I find this
*pretty lame but I don't know what else to do. Hopefully this will improve
*compile times when using the Appkit in other programs.
*
*Revision 1.12  2003/08/09 02:56:43  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 1.11.2.4  2003/07/28 23:49:58  ddiego
*check in of the weekend's work from July 25
*learned how to use agg image renedering, now have to integrate it into the
*GraphicsKit - alos enabled setting a viewable bounds that sets the agg cliprect
*as well, useful for later optimizations
*
*Revision 1.11.2.3  2003/07/07 03:52:08  ddiego
*added further osx porting code, primarily to the GraphicsKit - hey we can
*draw lines ! Woot!
*
*Revision 1.11.2.2  2003/06/23 23:16:54  ddiego
*added some furtther implementation for the osx port
*
*Revision 1.11.2.1  2003/06/16 03:09:39  ddiego
*beginning to add support for AGG into the VCF GraphicsKit
*added some missing files
*added some changes to the new version of xmake
*
*Revision 1.11  2003/05/17 20:37:10  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 1.10.10.4  2003/04/19 22:22:55  ddiego
*tested the code developed in windows using gtk in linux. Seems to work ok except for a
*few minor compiler glitches. Had to comment out the partial specialization for
*floating point image bits in include/graphics/ImageBits.h. Also made some
*adjustments in the makefiles for building the GraphicsKit and ApplicationKit
*from the build/make/Makefile.
*
*Revision 1.10.10.3  2003/04/17 04:29:47  ddiego
*updated scintilla, added gtk support for the application kit, with stubs
*for the basic peers.
*
*Revision 1.10.10.2  2003/04/07 03:39:30  ddiego
*did some documentation work, and got everything to compile cleanly with some
*of the new additions, particularly the chnages inteh Image/ImageBits classes.
*
*Revision 1.10.10.1  2003/03/12 03:10:25  ddiego
*switched all member variable that used the "m_"<name> prefix to
* <name>"_" suffix nameing standard.
*Also changed all vcf builder files to accomadate this.
*Changes were made to the Stream classes to NOT multiple inheritance and to
*be a little more correct. Changes include breaking the FileStream into two
*distinct classes, one for input and one for output.
*
*Revision 1.10  2002/09/12 03:26:04  ddiego
*merged over the changes from the devmain-0-5-5b branch
*
*Revision 1.9.12.1  2002/08/06 02:57:35  ddiego
*added base X11 files for GraphicsKit and made sure that the GraphicsKit compiles
*under linux (GCC). There is now a new dir under build/xmake called GraphicsKit
*where the xmake build script lives. This checkin also includes the base X11
*include (as part of GraphicsKitPrivate.h), as well as linking to the X11 libs
*
*Revision 1.9  2002/01/24 01:46:48  ddiego
*added a cvs "log" comment to the top of all files in vcf/src and vcf/include
*to facilitate change tracking
