       POLYTYPE_ATEX - Polygon rendering mode type Allegro game programming library.


       #include <allegro.h>

       #define POLYTYPE_ATEX


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