// $Log$
// Revision 1.19  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 1.18  2004/10/28 14:16:01  basch
// Class comment changed (Doxygen style)
//
// Revision 1.17  2004/03/23 09:37:41  kirsch
// added alignment
//
// Revision 1.16  2004/03/12 16:28:41  baumann
// macros VRS_NAMESPACE_BEGIN/_END expanded and removed
//
// Revision 1.15  2004/02/16 16:42:08  baumann
// - moved class VRS::SceneNode from "vrs/sg/" to "vrs/"
// - renamed class VRS::SceneGraphVisitor to class VRS::SceneNodeVisitor
//     and moved it from "vrs/sg/" to "vrs/"
//
// Revision 1.14  2004/01/19 11:43:59  baumann
// serialization mechanism improved
//
// Revision 1.13  2003/11/07 14:19:25  kirsch
// removed leading underscore from include guards
//
// Revision 1.12  2003/07/22 16:16:03  baumann
// class Visitor renamed to class SceneNodeVisitor
//
// Revision 1.11  2002/10/29 10:32:53  baumann
// macros VRS_CLASSNAME_* and VRS_IMPL_TYPEINFO_* removed
//
// Revision 1.10  2002/10/28 17:12:23  buchholz
//  - traverse-method now returns SceneNodeVisitor::TraversalFlag instead of int
//  - SceneNodeVisitor and travers method do not take an Engine parameter any more
//  - SceneNodeVisitor::visitScene now gets a bool parameter pushHint.
//  - Now visitScene is called twice for each object: One call with
//    pushHint==true, when the object is pushed, one call with pushHint==false,
//    when the object is popped.
//
// Revision 1.9  2002/03/03 21:44:26  kosta
// VRS_TYPEINFO-macro rewritten
//
// Revision 1.8  2002/02/19 10:34:20  kosta
// undone all changes since 2002-02-15
//
// Revision 1.5  2002/02/05 07:48:26  kosta
// new persistency macros:
//     VRS_SERIALIZABLE(CLASS_NAME);
//     VRS_SERIALIZABLE_ABSTRACT_CLASS(CLASS_NAME);
//     VRS_SERIALIZABLE_NO_SO_CLASS(CLASS_NAME)
//
// Revision 1.4  2002/02/04 13:07:19  kosta
// VRS_SERIALIZABLE macros completely rewritten
//
// Revision 1.3  2002/01/15 16:25:55  kosta
