Discussion
You can associate the display link with any of the RunLoop modes, multiple input modes, or a custom mode. When the run loop is in mode, the display link notifies its delegate when the system prepares the next frame.
You can remove the display link from a run loop by calling remove(from:forMode:), or from all run loops with invalidate().
