   @helene ok apparently it's to have simple linear texture traversal

     @helene the idea is that while usually hardware does inverse texture mapping, that is, generate the polygons and then traverse them to produce the texture coordinates, quad-based hardware does forward texture mapping, traversing the texture directly and then interpolating for screen-space coordinates
