README for the Lighting 2 Program

This program shows the effects of the different reflective/lighting properties
that OpenGL is capable. You should notice how one of the spheres has a green highlight
to it-the effect of specifying a different hightlight color from the white specular color.

The scene is animated, so try the following keys:
HOME: Resets viewpoint to initial values (animation keeps going)
SHIFT-HOME: reset viewpoint & clear movement vectors
5: Clear movement vectors
Up/Down Arrows: change velocity in Z (if shifted, change rotation)
Left/Right Arrows: change velocity in X (if shifted, change rotation)
Plus/Minus: change velocity in Y (if shifted, change rotation)
ESC: Exit animation
