* clutter/clutter-timeline.h: * clutter/clutter-timeline.c (timeline_timeout_func), (clutter_timeline_get_delta): Add a function for retrieving the number of frames and the time (in milliseconds) elapsed since the last timeline ::new-frame signal. This can be useful for implementing a physics engine or just for knowing how if and how many frames have been skipped.
