--------------------------------------------
notes: It was nice to see an applet with rotation, so I can actually
see the brightness of the facets change as the normals change relative
to the light sources.  The problem you have with clipping can be fixed
by not homogenizing.  Because you can have overlap at infinity, you need
to perform clipping after transformation but before dividing through by w.
Code looks great, otherwise, although you didn't provide a method for
transforming normals.  You wouldn't need it, since you didn't use Gouraud
shading, but the project statement still lists it as a requirement.
