From 045612c90e53cd3c4e46c203b982f376d21ab13d Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Fri, 24 May 2013 13:37:13 -0700 Subject: intel: Add an assert for glCopyTexSubImage() being called on MSAA buffers. This is just in case someone else trips over this due to our weird reuse of this code in glBlitFramebuffer().
