This is preferable to the timer-based default implementation of QPlatformWindow, as it gives AppKit more control of when to schedule the update, and makes sure the update is scheduled along with other views in the normal display-cycle, reducing the number of push flushes we do. QtWidgets still need to plumb the update() method to updateRequest for that to have any real effect though. In the future we may consider scheduling the update via a display link, if the window surface is set up for GL, for example. Ideally we'd also have a platform hook for the repaint() method, so that we could funnel it through display and get synchronous painting with AppKit still taking care of drawing and compositing child views.
