Author: Anuj Phogat <[email protected]> Date: Fri Oct 18 16:07:42 2013 -0700 i965: Do not set bilinear_filter flag in case of multisample blits Setting bilinear_filter flag in case of multisample blits with GL_LINEAR filter causes incorrect behavior in translate_dst_to_src() function. This broke Modern Warfare (1, 2 and 3) on SNB, IVB and HSW. Tested on SNB and IVB, no Piglit regressions. Trace file of the game (taken with apitrace) works fine with this patch.
