  Actually the patch uses internally trace() to get the intersection points
with the surface (or at least the patch which I made does). :)

  In fact, I first made the tesselation with pov-SDL with the exact same
principles as the patch itself, but it was really, really slow, which was
the reason I decided to make it as a patch.
