Before I get any more e-mail on this topic, I apologize for jumping the gun
before I saw the code.  I haven't tried it yet, but I guess it's pretty obvious
he does know what texture mapping is.  I would like somebody to explain, though,
how his code resembles a simple line drawing algorithm.  I would also like to
hear some comments on the limitations of this method.
