mutter/clutter/clutter-main.h
Neil Roberts 827c26757e Applied patch from bug #881
* clutter/clutter-frame-source.h: 
	* clutter/clutter-frame-source.c:
	New files that contain a replacement for g_timeout that try to
	cope with system delays.

	* clutter/Makefile.am: Added clutter-frame-source.{c,h}

	* clutter/clutter-timeline.c (timeout_add): Use a frame source
	instead of a g_timeout.

	* clutter/clutter-main.c (clutter_threads_add_frame_source_full)
	(clutter_threads_add_frame_source): New public functions to wrap a
	frame source and grab the Clutter mutex.

	* clutter/clutter-timeout-pool.c: Now calculates the timeout
	expiration times in the same way as a frame source does so that it
	counts time in frame intervals instead of setting the next
	expiration time as an offset from the current time.
