I didn't see that, pushing too hard, I guess. OTOH, it still doesn't draw anything (in the main program). That square in the middle is a bevel drawn separately, the image should be inside it.
Whoopsy, I tried it in the example program just for completeness, and it showed the squares! I should be able to figure it out now. Thanks, Trent!
Well, no. I'll just malloc a block, set some "pixels" and glBindTexture() it like the FSM intended.
