This uses CVDisplayLink to drive the GdkFrameClock. A GdkWindow can register a frame callback to thaw their frame clock as necessary based on the next notification from CVDisplayLink. CVDisplayLink notifies us on a high-priority thread. We use the same NSEventas gdkeventloop-quartz.c to wakeup the main loop. This is done so that we don’t pathologically wake up the select thread to then continue notifying the main loop. We use an embedded GList node in the GdkWindowImplQuartz so that we can avoid allocating any lists or arrays for pending frame callbacks. Compare this to the same design in GdkWindow for children.
