Owen W. Taylor 6705ce6c6a Move elapsed-time calculations into ClutterTimeline 
Instead of calculating a delta in the master clock, and passing that
into each timeline, make each timeline individually responsible for
remembering the last time and computing the delta.

This:

 - Fixes a problem where we could spin infinitely processing
   timeline-only frames with < 1msec differences.
 - Makes timelines consistently start timing on the first frame;
   instead of doing different things for the first started timeline
   and other timelines.
 - Improves accuracy of elapsed time computations by avoiding
   accumulating microsecond => millisecond truncation errors.

/* This test runs three timelines at 30 fps with 10 frames. Some of
the timelines have markers. Once the timelines are run it then
checks that all of the frames were hit, all of the markers were hit
and that the completed signal was fired. The timelines are then run
again but this time with a timeout source that introduces a
delay. This should cause some frames to be skipped. The test is run
again but only the markers and the completed signal is checked
for. */
