From 4bbd12036819ed6a2d0993c437e0c02bf0c92b0b Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 1 Aug 2012 12:38:56 -0700 Subject: [PATCH] mesa: Fix glPopAttrib() behavior on GL_FRAMEBUFFER_SRGB. I happened to notice this while looking at a blit pass in l4d2, which had an optional push/pop around framebuffer srgb setting. It didn't matter in the end, but the fix is sitting in my tree now.
