This adds a performance tracking framework that can run a set of tests over specified git revisions. The ruby script for generating the reports comes from similar performance tracking in GEGL. The framework permits evaluating new tests against older version of clutter. The tests themselves go through a few hoops for disabling framerate limiting in both mesa and clutter. When running make check the tests will be run and lines of the form: @ test-state: 40.51 fps will be left in the output, a script can scrape these lines out of a build log on a buildbot to in other ways track performance.
