TiledTextureImage breaks BeginUpdate/EndUpdate in these cases: - The update is encompassed by more than one tile - The update is encompassed by a single tile that isn't the first tile - The update is a non-rectangular region that covers more than one tile Fixed by using signed instead of unsigned integers in tile loops, correcting an incorrect device offset and correcting the region returned by BeginUpdate.
