// $Log$
// Revision 1.26  2005/01/03 01:43:08  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 1.25  2004/06/28 09:44:52  kirsch
// changed mesh orientation
//
// Revision 1.24  2004/06/27 12:57:53  kirsch
// forward included iterator
//
// Revision 1.23  2004/03/12 16:28:38  baumann
// macros VRS_NAMESPACE_BEGIN/_END expanded and removed
//
// Revision 1.22  2004/01/19 11:43:57  baumann
// serialization mechanism improved
//
// Revision 1.21  2003/11/07 14:19:24  kirsch
// removed leading underscore from include guards
//
// Revision 1.20  2003/07/23 17:04:49  baumann
// code cleanup (especially untabified)
//
// Revision 1.19  2003/05/21 10:23:42  baumann
// changes due to iVRS
//
// Revision 1.18  2003/05/21 08:00:00  nienhaus
// namespace changed for PrimitiveType
//
// Revision 1.17  2003/05/21 07:22:06  baumann
// changes due to iVRS
//
// Revision 1.16  2003/05/19 14:09:17  kirsch
// PolygonSet/Mesh contain per-vertex data now which have an abstract meaning
//     instead of being directly bound to hardware registers. The mapping to
//     the graphics hardware is done by the VertexAttributeMap attribute.
// Mesh inherits from PolygonSet now
// removed MeshSimplifier (handled by PolygonSetPainterGL now)
// removed legacy rendering path in PolygonSetPainterGL (all Iterators are
//     now rendered as vertex arrays even if this means converting them first)
//
// Revision 1.15  2003/04/16 12:02:43  kirsch
// allow construction of an empty mesh
//
// Revision 1.14  2003/04/15 13:03:44  kirsch
// added 3 additional texture coord iterators to polygonset, lineset,
// pointset and mesh
//
// Revision 1.13  2002/10/29 10:32:52  baumann
// macros VRS_CLASSNAME_* and VRS_IMPL_TYPEINFO_* removed
//
// Revision 1.12  2002/03/06 13:25:35  kosta
// classes Mesh and MeshSimplifier completely rewritten
//
// Revision 1.11  2002/03/05 20:21:23  kosta
// mesh-interface cleaned up
