    Description

      From QTBUG-63026 : the idea is

      https://gist.github.com/torarnv/419861f23ea7528ac52d677b129d4da7

      based on

      http://www.cocoabuilder.com/archive/cocoa/315032-transition-from-nsevent-phase-to-nsevent-momentumphase.html

      We've known for years that this was an issue, but now we know how to fix it, so it would be nice to get that done for 5.11. Then I can remove the timer from QQuickFlickable, which currently waits for the movement to stop before emitting signals such as movementEnded, and has had bugs more than once.
