Project Mode7

There really isn't a practical way to do it in Graal. All of the native transforms that Graal uses are done in screenspace with no 3D projection whatsoever, even writing your own projection for verts results in broken interpolation of the texture you assigned to the polygon. When I did this, the only way I could get it at a reasonable speed was with showimgparts with larger parts near the bottom, and increasing the texel density as it reached further off the screen.

Unfortunately, even with precomputing all of the math that's possible to precompute into lookup tables, rendering was still the bottleneck. I don't think there is a reasonable way to accomplish this in Graal unless you do something with an external server/process in some manner. Keep in mind you can embed Flash, so I guess that's the cheap way.
