* clutter/clutter-marshal.list: Add signature for the ::marker-reached signal marshaller. * clutter/clutter-timeline.[ch]: Add timeline marker API; using markers it is possible to add a unique identifier to a particular frame of the timeline, and receive a signal notification when reaching that particular marker while playing the timeline. (#641) * tests/test-timeline.c: Update the test case to check for the marker-reached signal emission. * clutter.symbols: Add new symbols.
