Subject: compute_composite_region32: Zero extents before returning FALSE.
X-Git-Tag: 1.0_branch~462
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0742ba41646853a5edf90c2f3102f49b248321ee;p=profile%2Fivi%2Fpixman.git

compute_composite_region32: Zero extents before returning FALSE.

If the extents of the composite region are broken such that x2 <= x1
or y2 <= y1, then we need to zero the extents before returning so that
the region won't be completely broken when calling
pixman_region32_fini().
