From fceff14450e48a90778e0d1e79c13fa7a40631e6 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 5 Jun 2013 23:19:27 -0700 Subject: [PATCH] mesa: Add a _mesa_problem to document a piglit failure on i965. Having figured out what was going on with piglit fbo-depth copypixels GL_DEPTH_COMPONENT32F (falling all the way back to swrast on CopyPixels to a float depth buffer), I'm not inclined to fix the problem currently but it seems worth saving someone else the debug time.
