That's exactly what I had done (thanks to the UV mapping macro) but
it's all gone now. Anyway, I abandoned the problem because I ran into
a great problem with adaptive mesh subdivision (more precisely, POV's
arrays being static). Without it, great deformations were a pain,
especially near the image edges, and parsing was slow enough with a
20000 triangles mesh, so I gave up on non-adaptive subdivision. It
doesn't matter anymore either way.
