From 15e309cf84444a8f9ce7f7c86f0a0f391721bc50 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Tue, 27 Dec 2011 16:42:44 -0800 Subject: [PATCH] intel: Fix bad read/write flags on self-copies for glCopyBufferSubData(). We didn't consume these flags in any way that would produce a functional difference, but we might have some day.
