This adds HyperZ support, without fast clear for now. I got a lot of help from Marek with this. There seem to be no piglit regressions; about 60 very basic GL1.0 tests were skipped in my test run for some reason - they looked very unrelated. There was no change in other tests.

It does seem to make a difference for performance - running a Xonotic demo with custom high graphics settings on a Radeon HD 7750 - Before: 2351 frames 117.2196701 seconds 20.0563608 fps, one-second fps min/avg/max: 14 21 28 (75 seconds) After: 2590 frames 116.1412549 seconds 22.3004306 fps, one-second fps min/avg/max: 16 23 30 (82 seconds) _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
