OpenGL specification 3.3 (page 196), section 4.1.3 says: If drawbuffer zero is not NONE and the buffer it references has an integer format, the SAMPLE_ALPHA_TO_COVERAGE and SAMPLE_ALPHA_TO_ONE operations are skipped." This should work properly even if there are other draw buffers that are not in integer format. This patch makes following piglit tests pass on mesa: int-draw-buffers-alpha-to-coverage int-draw-buffers-alpha-to-one Reviewed-by: Chad Versace <chad.versace@linux.intel.com> Reviewed-by: Ian Romanick <ian.d.romanick@intel.com> Signed-off-by: Anuj Phogat <anuj.phogat@gmail.com>
