Revert "fix: out-of-bounds access when bg not in color map" 

with this patch certain gif images will fail to play. one other problem
here is that it suddenly breaks the loop without free-ing data and rows,
leading to a memory leak.

regardless, this needs to be investigated further.

here's an example image where this happens:
