Oops, too bad I didn't notice it's supposed to happen in sampler. Why that isn't 
called - I think it's because that check at line 2415 is inside

if(stateblock->textures[sampler]) {

block. Since the app is setting texture to NULL, it's not entering. Taking the 
colorkey part out of this block helps. I guess it will be a better fix then.
