Thanks a lot, this is very helpful for me. As far as I can tell this only
works when you use pyglet.image.load -- not pyglet.resource.image -- to
load an image file. I am unsure why... Something to do with different
classes (ImageData vs. Texture vs. TextureRegion) perhaps?
Is pyglet.resource.image supposed to be more efficient?
