mutter/clutter/clutter-timeline.h
Emmanuele Bassi 477db755b7 2008-03-18 Emmanuele Bassi <ebassi@openedhand.com> 
* clutter/clutter-score.[ch]: Remove all the API changes, and
	just add a clutter_score_append_at_marker(); the implementation
	remains the same, but the marker must be explicitly created by
	the developer. The ids are no longer used to create implicit
	markers, so they can return to be unsigned integers.

	* clutter/clutter-timeline.[ch]:
	(clutter_timeline_has_marker): Add a function to query a timeline
	for a marker being set.

	* tests/test-score.c (main): Update with the API changes.

	* clutter.symbols: Update exported symbols.
