*More header musical chairs
*
*Revision 1.2.2.3  2003/09/21 04:15:34  ddiego
*moved the cvs info data to teh bottom of the header instead of the
*top so it is easier to get to the actual header class declarations
*instead of having to wade through all the cvs info stuff.
*
*Revision 1.2.2.2  2003/09/12 00:09:32  ddiego
*added better tabbing behaviour - fixed an earlier bug.
*Code is easier to understand and it simplified the implementation
*a bit as well
*Moved around the RTTI definitions for various Appkit classes to a
*single inline and stripped them from the various class headers
*
*Revision 1.2.2.1  2003/08/27 20:11:49  ddiego
*adjustments to how hte DataObject class work and copy/paste
*
*Revision 1.2  2003/08/09 02:56:42  ddiego

*the VCF
*
*-Added a Document/View architecure that is similar to MFC's or NextSteps's
*Doc/View architectures

*now basic support for it in terms of drawing vector shapes
*(fills and strokes). Image support will come in the next release

*
*Revision 1.1.2.2  2003/06/27 03:10:58  ddiego
*got rid of some redundant junk in the Clipboard and DataObject
*classes. Instead of a rather dippy use of the DataType calss, we now simply
*use pure mime-types to identify the various "flavours" of data.
*
*Revision 1.1.2.1  2003/06/16 03:09:39  ddiego
*beginning to add support for AGG into the VCF GraphicsKit
*added some missing files

*distinct classes, one for input and one for output.
*
*Revision 1.3  2003/02/26 04:30:37  ddiego
*merge of code in the devmain-0-5-9 branch into the current tree.
