// Revision 1.19  2005/01/03 01:43:07  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  2004/11/05 13:58:09  basch
// Class comment changed (Doxygen style)
//
// Revision 1.17  2004/03/12 16:28:38  baumann
// macros VRS_NAMESPACE_BEGIN/_END expanded and removed
//
// Revision 1.16  2004/01/19 11:43:56  baumann

// code cleanup (especially untabified)
//
// Revision 1.13  2003/05/16 05:19:33  baumann
// - new method: bool Vector::isOrigin() const;
// - added keyword "explicit" to some ctors of some base classes
//   (e.g. Color, Vector, Bounds, Matrix, Area, ...)
// - function abs(const Vector& v) removed (Vector::abs() still exists!)
// - function abs2(const Vector& v) removed (Vector::abs2() still exists!)
// - vertexdata.tli added
//
// Revision 1.12  2003/02/13 20:23:31  skirsch
