triangle3d, triangle3d_f - Draws a 3d triangle onto the specified bitmap. Allegro game programming

       Draw 3d triangles, using  either  fixed  or  floating  point  vertex  structures.   Unlike  quad3d[_f](),
       triangle3d[_f]()  functions are not wrappers of polygon3d[_f](). The triangle3d[_f]() functions use their
       own routines taking into account the constantness of the gradients. Therefore  triangle3d[_f](bmp,  type,
       tex, v1, v2, v3) is faster than polygon3d[_f](bmp, type, tex, 3, v[]).

       Read  the  beginning  of  chapter "Polygon rendering" for a list of rendering types you can use with this
       function.
