Well, Allegro's aren't dead slow, they're just not THAT fast...  I mean,
they're very usable if you just use the low-level 3d-math routines to
write your own engine... I'd replace the triangle 3D, though...  Anyway,
if you want a FAST triangle filler, check out http://coders.base.org and
read Issue one of the IRC-Zine...  Download WGTTUT*.ZIP from there and
you'll be well on your way...

The other things I wish somebody would add are Phong support and 3DS
support.  I might do this, but if anybody wants to, EMail me and I'll send
you some documents on Phong and a 3DS Reader...
