Anyone who has programmed 3D in DJGPP and Allegro knows about Allegro's
persp_project function.  This function takes a set of XYZ points and
projects them onto the 2D screen (quite well, I might add).

I'm currently writing a 3D isometric engine a la Dungeon Keeper,
Syndicate Wars, and Ultima IX (before it was turned into a 3D action
game).  Which means that I DON'T want to correct the perspective with
respect to the Z axis.  Anyone out there know a way to do this with
Allegro's current functions, or am I going to have to come up with a
no_persp_project?  (Which, naturally, I'll share with everyone once it
gets debugged).

Thanks.
