Perhaps I should look up the manual sections on bounding...

Yes, I have... it seems to be a hole rather than a plane!

No, I did not touch the code since!

Yes, it does, as the image_map extends from <0, 0, 0> to <1, 1, 0>, 
eval_pigment() goes from
<(0.5+0)*(1/800), (0.5+0)*(1/400), 0> to <(0.5+799)*(1/800), 
(0.5+399)*(1/400), 0>!

See you in Khyberspace!
