 * PRODUCTION: UPGRADED [CATCHUP_003] Dev-tree R1.5
 *
 * Revision 1.5  2004/01/27 18:29:20  dicuccio
 * Code clean-up.  Pass by const-ref instead of value for CRgbaColor
 *
 * Revision 1.4  2003/06/18 16:41:00  meric
 * First phase of print reorg: remove dependence on gui/opengl and OpenGL
 * except for class COpenGLPrintBuffer
 *
 * Revision 1.3  2003/06/16 15:55:58  dicuccio
 * Work-in-progress: everything compiles, still much reorganization to be done.
 * Moved generic functionality out of opengl/print/ and into gui/utils (print
 * options, print dialogs, etc.).  Removed interactive state from CGlCanvas.
 * Added hook in CView for opening standard print dialog, and for generic print
 * handling.
 *
 * Revision 1.2  2003/06/16 12:46:21  dicuccio
 * Clean-up after initial commit
 *
 * Revision 1.1  2003/06/13 19:00:30  meric
 * Initial version
