From d9e35d51fd9bb5d67865a451d16cf61c66f16a11 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 13 May 2009 18:18:29 -0700 Subject: [PATCH] intel: Use GL_FRONT_AND_BACK for stencil clearing. This comes from a radeon-rewrite fallback fix, but may also fix stencil clear failure when the polygon winding mode is flipped.
