If your mouseMoveEvent() neither ignores events nor passes them on
directly to QtCanvasView::mouseMoveEvent() (which itself ignores events),
then your contentsMouseMoveEvent() will never be called, because the viewport
will never receive the event. contentsMouseMoveEvent() is a wrapper for
the mouseMoveEvent() function belonging to the viewport.
