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.
