Cocoa: No resizeEvent after calling QWindow::resize

The QWindow::resizeEvent documentation states that resizeEvent is invoked after the windowing system has acknowledged a setGeometry() or resize() request.

This is not the case on Mac OS X.

The problem became obvious when trying to handle window size changes on the c++ side after modifying the width/height properties of a qml root element with resize mode QQuickView::SizeViewToRootObject.
