Owen W. Taylor dcd8d28314 Limit the frame rate when not syncing to VBLANK
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.
