Subject: intel: Respect src pitch in _mesa_copy_rect().
X-Git-Tag: mesa-7.9-rc1~4546
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e1e48ea15c1fe448f0b69e086b66c1123dc98bb7;p=platform%2Fupstream%2Fmesa.git

intel: Respect src pitch in _mesa_copy_rect().

If a non-zero src_y was used, this would break piglit
depth-level-clamp.
