FrameClock.requestPhase

Asks the frame clock to run a particular phase. The signal corresponding the requested phase will be emitted the next time the frame clock processes. Multiple calls to [gdk.frame_clock.FrameClock.requestPhase] will be combined together and only one frame processed. If you are displaying animated content and want to continually request the [gdk.types.FrameClockPhase.Update] phase for a period of time, you should use [gdk.frame_clock.FrameClock.beginUpdating] instead, since this allows GTK+ to adjust system parameters to get maximally smooth animations.
