From ff7aa554a11863de2c4c0b4b6d1ec7b07c819739 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Sun, 12 Sep 2010 06:31:30 +1000 Subject: mesa/swrast/st: add ARB_occlusion_query2 support. This gets my vote for most pointless extension of all time, I'm guessing some driver could possibly optimise for this instead of counting it might just get a true/false, but I'm not really sure. need this to eventually advertise 3.3 despite its total uselessness.
