Yeah, that 60000 number plays havoc with a bunch of things. You get a
lot of z-bleeding because the clipping planes are spread so far apart.
Maybe I get less depth bits on the offscreen buffer. Gotta check. And
I suppose I should borrow the l3p bounding box/sphere? algorithm from
the ldview sources and use that to set the clipping planes. Of course
I've sorta been waiting for the new l3p before trying most of this stuff
because then you can use a real ortho view and skip tiny viewing angle
and teloscopic view stuff. Oh well.

Sure. So did you want me to fix the -mS and aspect ratio calculation,
or do you have a viable workaround?
