From 808024689247561d3de225856fb6ef17430fd39e Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Thu, 21 Jul 2011 09:15:05 -0700 Subject: [PATCH] meta: Also save/restore clip planes for GLSL. Fixes user-clip on 965 with 3D clears enabled. I created a separate flag because I wanted to avoid the overhead of the matrix operations in this path.
