*CVS Log info
*$Log$
*Revision 1.3  2004/12/02 04:11:10  ddiego
*removed some old, extraneous files from graphics kit dir.
*
*Revision 1.2  2004/08/07 02:49:16  ddiego
*merged in the devmain-0-6-5 branch to stable
*
*Revision 1.1.2.3  2004/07/09 03:39:30  ddiego
*merged in changes from the OSX branch for new theming API. Added
*support for controlling the use of locale translated strings in components.
*
*Revision 1.1.2.2.2.1  2004/07/06 03:27:13  ddiego
*more osx updates that add proper support
*for lightweight controls, some fixes to text layout, and some window painting issues. Also a fix
*so that controls and windows paint either their default theme background or their background
*color.
*
*Revision 1.1.2.2  2004/04/29 04:10:26  marcelloptr
*reformatting of source files: macros and csvlog and copyright sections
*

*migration towards new directory structure
*
*Revision 1.3.4.1  2004/04/26 21:58:38  marcelloptr

*merge from devmain-0-6-2 branch into the stable branch
*
*Revision 1.2.2.1  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 1.2  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 1.1.2.1  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
