From e60ebebb392d1d4c47541766737b5a79685a24d5 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Tue, 3 Nov 2009 09:30:20 -0700 Subject: [PATCH] st/mesa: don't use util_blit_pixels_writemask() for depth or depth/stencil util_blit_pixels_writemask() only works for color formats at this time. Also, it might never work for depth/stencil surfaces since we can't get handle stencil values in a fragment shader.
