This test seems to be quite broken on OS X: qWaitForWindowExposed returns too early (while no window is on screen) so gestures can not be dispatched QApplication::topLevelAt(pt) - returns null. Use qWait + isExposed combo instead (similar to qWaitForWindowExposed, but there is no isExposed test before the loop).

The hardest usecase to get right is when we remove a recognizer while several

for the same type (thus replacing the old one).
|

The expected result is that all old gestures continue till they are finished/cancelled

and the new recognizer starts creating gestures immediately at registration.

This implies that deleting of the recognizer happens only when there are no more gestures

that it created. (since gestures might have a pointer to the recognizer)
