OSX fix updates during resize
While resizing MacOS suspends the NSDefaultRunLoopMode. So in this
caae we can't post to the system event loop, but must use timers
to restart ourself.
Since the timer itself is scheduled on the NSEventTrackingRunLoopMode
it' also triggers on resize events.
There is still some minor glitch: when resizing too fast some part of
LibreOffice isn't painted, while the left mouse button is down.
Since there isn't any layouting triggered by the mouse up, there has
to be an other inconsistency.

+Generally the Scheduler is handled as expected, except on resize, which is
+handled with different runloop-modes in MacOS. In case of a resize, the normal
+runloop is suspended in sendEvent, so we can't call the scheduler via posted
+main loop-events. Instead the schedule the timer again.

Probably that's the reason, why some code comments spoke of lost events and
there was some distinct additional event processing implemented.
