This may be obvious, and I've simply overlooked it, but I can't seem to
figure out a way to explicitly say what color I want at a specific point
on a surface. Basically what I want is a way to draw the u and v
coordinate lines ...u = -2, u = -1, u = 0, u = 1, u = 2 ...,...v = -2, v
= -1, v = 0, v = 1, v = 2 ..., etc.
This *seems* like it should be easy. Suggestions?
