 *
 * Revision 1.5  2004/05/03 12:44:50  dicuccio
 * Added #include for gui/gui.hpp.  Fixed compiler warning about double -> float
 * conversion
 *
 * Revision 1.4  2003/09/29 15:20:08  dicuccio
 * Deprecated gui/scope.hpp.  Merged gui/core/types.hpp into gui/types.hpp
 *
 * Revision 1.3  2003/06/27 17:38:46  meric
 * Added "point" and "pt" as text and symbol respectively for PDF unit
 *
 * Revision 1.2  2003/06/24 17:24:28  meric
 * Added typdefs TInch, TMillimeter and TPdfUnit.
 *
 * Revision 1.1  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
