QGraphicsVideoItem does not override QGraphicsItem::type()

QGraphicsVideoItem does not override the virtual function QGraphicsItem::type(). This prevents qgraphicsitem_cast(..) from distinguishing QGraphicsVideoItem instances from any other QGraphicsItem-derived object that does not override type() or has a type() function that returns 65536 (UserType).

This can be a problem in a number of cases, but is particularly problematic for PyQt: http://www.riverbankcomputing.com/pipermail/pyqt/2015-January/035302.html

Edit: This can't happen before Qt 6.0 as it breaks binary compatibility.
