23 * The original code for this mode was written by Mark J. Kilgard
24 * as a demo for openGL programming.
26 * Porting it to xlock was possible by comparing the original Mesa's morph3d
27 * demo with it's ported version to xlock, so thanks for Marcelo F. Vianna
28 * (look at morph3d.c) for his indirect help.
30 * Thanks goes also to Brian Paul for making it possible and inexpensive
31 * to use OpenGL at home.
