Um, well, actually it would seem to me that most of the routines are quite
slow. I was just saying that the face sort could be much faster (from
experience.) For example, I implemented something of a face sort using the
regular allegro 3D routines and got at least 50% more speed than I would
have if I had used the P3D routines. There's obvously something in there
that's causing the whole thing to slow down. I don't think the z-buffering
stuff should be messed with, because that's slow to begin with :) (In
software, anyway) The z-buffer routines, for software ones, are actually
quite nice, but I was just _really_ surprised that the face sort was so
slow! Perhaps doing something like a radix sort would make it better? (I
hear that's one of the fastest :)
