*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
