timed presentation related wl_surface requests
The main feature of this interface is accurate presentation timing feedback to ensure smooth video playback while maintaining audio/video synchronization. Some features use the concept of a presentation clock, which is defined in the presentation.clock_id event.
A content update for a wl_surface is submitted by a wl_surface.commit request. Request ‘feedback’ associates with the wl_surface.commit and provides feedback on the content update, particularly the final realized presentation time.
When the final realized presentation time is available, e.g. after a framebuffer flip completes, the requested presentation_feedback.presented events are sent. The final presentation time can differ from the compositor’s predicted display update time and the update’s target time, especially when the compositor misses its target vertical blanking period.
