00026  * Revision 1.6  2005/12/19 01:41:44  alexis
00027  * Properly separated the level 1 and 2 of 2D geometry
00028  *
00029  * Revision 1.5  2005/12/19 01:38:20  alexis
00030  * Added all the 2D geometry shape support
00031  *
00032  * Revision 1.4  2005/12/18 10:43:31  alexis
00033  * This version includes the Sphere and some fixes to the other shapes (some
00034  * would use the wrong direction, I added some front face CW.)
00035  *
00036  * Revision 1.3  2005/12/17 09:20:45  alexis
00037  * Got the Box, Cone, Cylinder to work very nicely!
00038  *
00039  * Revision 1.2  2005/12/11 09:17:23  alexis
00040  * First working version. This can be used to render a Box.
00041  * Supports the Viewpoint and Materials in an Appearance node.
00042  *
00043  * Revision 1.1  2005/12/07 21:23:14  alexis
00044  * Added header and .c++ files to support OpenGL
