Subject: Use the tiled flag in the sarea to determine region tiling.
X-Git-Tag: 062012170305~19989
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3943d7f8b12370dd77dda66e70aa8f1fcd217f9f;p=profile%2Fivi%2Fmesa.git

Use the tiled flag in the sarea to determine region tiling.

This fixes mis-rendering if back/depth fail to get set up as tiled.  While it
probably won't ever be the case now that the pitch limits are loosened, this is
still the right thing to do.
