Some users report hitting a divide by 0 with the tile split in certain apps. Tile_split shouldn't ever be 0 unless the surface structure was not properly initialized. I think there may be some cases where mesa uses an improperly initialized surface struct, but I haven't had time to track it down.

It would be good to know where the bogus tile split is coming from though — who knows what else might be wrong in that case?
