16 An affine texture mapped polygon. This stretches the texture across the
17 polygon with a simple 2d linear interpolation, which is fast but not
18 mathematically correct. It can look OK if the polygon is fairly small
19 or flat-on to the camera, but because it doesn't deal with perspective
20 foreshortening, it can produce strange warping artifacts. To see what
21 this means, run Allegro's test program and see what happens to the
22 polygon3d() test when you zoom in very close to the cube.
