Subject: intel: Respect src pitch in _mesa_copy_rect().
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4980891252f35a2c87ef302b40d7536327a9babd;p=mesa.git

intel: Respect src pitch in _mesa_copy_rect().

If a non-zero src_y was used, this would break piglit
depth-level-clamp.
(cherry picked from commit e1e48ea15c1fe448f0b69e086b66c1123dc98bb7)
