The timing information in a gdk.frame_timings.FrameTimings is filled in
incrementally as the frame as drawn and passed off to the
window system for processing and display to the user. The
accessor functions for gdk.frame_timings.FrameTimings can return 0 to
indicate an unavailable value for two reasons: either because
the information is not yet available, or because it isn't
available at all.
Once this function returns true for a frame, you can be
certain that no further values will become available and be
stored in the gdk.frame_timings.FrameTimings.
Returns whether timings are complete.
