From 4a3b28113c3d23ba21bb8b8f5ebab7c567083a6d Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Sat, 19 Feb 2011 16:48:24 -0800 Subject: [PATCH] i965/fs: Correctly set up gl_FragCoord.w on Sandybridge. pixel_w is the final result; wpos_w is used on gen4 to compute it. NOTE: This is a candidate for the 7.10 branch.
