well [pix_texture] does simply load a pixbuffer into texture-ram.
it does know nothing about texture-coordinates. (these are handled by 
[pix_coordinates])

[pix_texture2] does load an image into texture-ram as a sub-texture (of 
a black master-texture) with  coordinates set so it appear as a "normal" 
(full) texture.
thus it enables you to use images that are not power-of-2 as textures 
without expensive rescaling
it is copy'n'pasted from pix_movie.

it might not be that elegant (as would be 
[pix_subtexture]+[pix_coordinates]) but i think it is easier for 
handling, since you do not need to know the size of the img.
