1999/09/14 03:23:08 gareth * Fixed GLUtriangulatorObj again (spelling). * * Revision 1.4 1999/09/14 01:32:58 gareth * Fixed definition of GLUtriangluatorObj for 1.3 tessellator. * * Revision 1.3 1999/09/11 11:34:21 brianp * added GLU_EXT_get_proc_address * * Revision 1.2 1999/09/10 02:08:18 gareth * Added GLU 1.3 tessellation (except winding rule code). * * Revision 1.1.1.1 1999/08/19
