*reformatting of source files: macros and csvlog and copyright sections
*
*Revision 1.1.2.1  2004/04/28 03:40:31  ddiego
*migration towards new directory structure
*
*Revision 1.5.4.1  2004/04/26 21:58:42  marcelloptr

*Revision 1.5  2003/12/18 05:15:58  ddiego
*merge from devmain-0-6-2 branch into the stable branch
*
*Revision 1.4.2.1  2003/11/01 20:39:35  ddiego

*
*Revision 1.4  2003/08/09 02:56:44  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

*ApplicationKit to take command line parameters
*FoundationKit now allows you to retreive the commandline (it's stored)
*start up has changed from appMain() to main()
*added a custom GTK widget class for use in the various GTK peers - this will
*allow us to specify absolute positioning and let the VCF handle layout
*issues
*Miscellaneous clean in various interfaces
*removed the Rect, Point, and Size classes from the FoundationKit
*and moved them to the GraphicsKit
*
*Revision 1.3  2003/05/17 20:37:11  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 1.2.2.2  2003/04/17 04:29:48  ddiego

*for the basic peers.
*
*Revision 1.2.2.1  2003/03/12 03:10:53  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 1.2  2003/02/26 04:30:40  ddiego
*merge of code in the devmain-0-5-9 branch into the current tree.

*finished up the GTKImage class. Now putting in text rendering with pango support
*
*Revision 1.1.2.1  2003/02/20 02:46:02  ddiego
