+ * 
+ * Porting it to xlock  was possible by comparing the original Mesa's morph3d 
+ * demo with it's ported version to xlock, so thanks for Marcelo F. Vianna 
+ * (look at morph3d.c) for his indirect help.
+ *
+ * Thanks goes also to Brian Paul for making it possible and inexpensive
+ * to use OpenGL at home.
