The tiling works fine, but it is extremely slow compared to
rendering the whole image in one piece.

Considering that we are considering parallel projections, the
concept of an "eye" position is rather strange.

| (...) Wow! Lots of bugs reports all at once. Where do I start? I don't know what's up with xvfb the aspect ratio problem. It seems odd since you can reshape an ldglite window and the aspect ratio is handled correctly. I guess I'll have to get xvfb (...) (25 years ago, 15-Oct-01, to lugnet.cad.dev)
