That occurred to me, but I am not able to implement that safely.
The event seems to be generated by QGraphicsView, then handled in the viewport
event and then passed to QGraphicsScene. But the user might install a subclass
of QGraphicsScene in the view and might inject other events, which would be of
the wrong type and cause a crash.
I cannot guarantee that I wouldn't be breaking anything.
