Ian Curtis	54c405709f	Need to walk back in memory and check the previous texture tiles to see if they overlap with the current textures being invalidated. If they overlap they must be cleared too. Algorithm is a bit brute forcy and more expensive than I'd like but it fixes the bad textures in Spikeout.	2016-11-22 20:30:10 +00:00
