-#   zrgb  (Requires Z buffer.)
-#
-# This program demostrates zbuffering 3 intersecting RGB polygons while
-# in doublebuffer mode where, movement of the mouse with the LEFTMOUSE 
-# button depressed will, rotate the 3 polygons. This is done by compound
-# rotations allowing continuous screen-oriented rotations. 
-#
-#    Press the "Esc" key to exit.
