<pre>Would a test case that just calls *SwapBuffers() at a fixed frequency be good
enough? And using glXGetSyncValuesOML or equiv to check the presentation jitter
as exposed to the application. (E.g.
piglit/tests/spec/glx_oml_sync_control/timing.c)
Bonus points for the test harness probing the infrastructure itself to find the
actual framerate.</pre>
