Roland Scheidegger 379db6a36b gallium: clean up resource_copy_region function ... Previously, surface_copy was said to allow overlapping blits, and it was "optional". However, some state trackers actually assumed it is always present, and quite some code (like in u_blit) assumed overlapping isn't allowed. Hence, resource_copy_region (and in the same spirit, resource_fill_region) is now mandatory, but overlapping blits are no longer allowed. A driver can plug in the cpu fallback util_resource_copy_region if it does not want to provide its own implementation, though this is not optimal.		2010-05-17 21:02:24 +02:00
