clutter-master-clock.c clutter-master-clock.h: When the SYNC_TO_VBLANK feature is not available, wait for 1/frame_rate seconds since the start of the last frame before drawing the next frame. Add _clutter_master_clock_start_running() to abstract the usage of g_main_context_wakeup() clutter-stage.c: Add _clutter_master_clock_start_running() clutter-main.c: Update docs for clutter_set_default_frame_rate() clutter_get_default_frame_rate() to no longer talk about timeline frame rates. test-text-perf.c test-text.c: Set a frame rate of 1000fps so that frame-rate limiting doesn't affect the result. http://bugzilla.openedhand.com/show_bug.cgi?id=1637 Signed-off-by: Emmanuele Bassi <ebassi@linux.intel.com>
