From ec4b8d16971b8860e14355f241ddcb2f82d5a5ee Mon Sep 17 00:00:00 2001 From: Chris Forbes Date: Sat, 29 Mar 2014 12:02:55 +1300 Subject: [PATCH] mesa: Fix format matching checks for GL_INTENSITY* internalformats. GL_INTENSITY has never been valid as a pixel format -- to get the memcpy pack/unpack paths, the app needs to specify GL_RED as the pixel format (or GL_RED_INTEGER for the integer formats). Note: This was briefly merged before, but exposed some breakage in gallium, so was reverted. Hopefully it will stick this time.
