Using the frame history stored in the frame clock, finds the last known presentation time and refresh interval, and assuming that presentation times are separated by the refresh interval, predicts a presentation time that is a multiple of the refresh interval after the last presentation time, and later than base_time.

Parameters:

this	a `GdkFrameClock`
base_time	base time for determining a presentaton time
refresh_interval_return	a location to store the determined refresh interval, or null. A default refresh interval of 1/60th of a second will be stored if no history is present.
presentation_time_return	a location to store the next candidate presentation time after the given base time. 0 will be will be stored if no history is present.
