A bit of a hack, but we need to do this until we can do tiled zs in sysmem (and associated tile/until blits for transfer_map). Fixes xonotic and glmark2 "refract", when reorder wasn't enabled. (reorder would paper over the issue by avoiding the extra round- trip to system memory and back to gmem. Signed-off-by: Rob Clark <robdclark@gmail.com>
