Thanks for the feedback.

Hmmm... Unfortunately, the Voodoo1/2 are probably going to be the hardest
to fix fullscreen bugs on, due to their unique architecture. Just out of
curiosity, do you have the latest drivers installed?

Thanks for the heads-up. I tracked down the cause of the problem; the part
is doing something I was under the (possibly mistaken) impression was a
no-no: those black sections are concave quads. Turn off lighting and you
will see that they are actually drawing the proper color, but the lighting
gets so messed up by their concavity that it comes out black. Anybody else
know whether this is kosher? I haven't seen it happen on any other parts.
I tracked down one of these quads; it's the following line:
4 16 -18 56 120 -24.4 51.6 127.7 -25.7 52.3 125.8 -27.7 52.6 124.4
Whether or not it's actually legit, I'll add code to split such quads into
two triangles. As it turns out, I already detect the problem, I just don't
do anything about it when I encounter it, so fixing it shouldn't be too
hard.
Looking at that part in detail, I discovered another bug in my color
handling which causes it to display some portions of the part in the wrong
color when you turn on edge drawing. It's especially obvious if you then
turn off lighting. I'll have to look into that too.
