Daniel van Vugt e7a210d963 clutter/frame-clock: Add dispatch jitter to frame timing measurements
Dispatch jitter is how much the dispatch interval has changed between
frames. It's a measure of sampling smoothness for events that are occurring
at a higher rate than the screen is refreshing:

 * Mouse movement
 * Clients rendering at swap interval zero
 * Keyframe animation position

Zero jitter is ideal but will practically never happen, and a jitter value
of several thousand microseconds will be visible to the naked eye as stutter
even if you're maintaining a perfect frame rate.

To make the numbers easier to interpret we also log the jitter as a
percentage of the refresh interval.
