// Revision 1.7  2005/01/03 01:43:10  klimetschek
// - modified win32 project layout, splitted vrs.vcproj into vrs_container, vrs_core, vrs_sg, vrs_image, vrs_opengl and vrs_io
// - removed vrs.vcproj
// minor things:
// - added all glutexamples to vrs4glut.sln
// - fixed some problems in glutexamples
// - removed all project references from all VS projects (using solution wide project dependencies instead)
//
// Revision 1.6  2004/11/03 14:45:07  saar
// Class comment changed (Doxygen style)
//
// Revision 1.5  2004/03/12 16:28:41  baumann
// macros VRS_NAMESPACE_BEGIN/_END expanded and removed
