-        initialization would prohibit deriving e.g. CanvasBase from
-        GraphicDeviceBase.
-
-        On top of that, disambiguates XEventListener::disposing and
-        WeakComponentImplHelper::disposing.
-
-        Having two virtual methods with the same name, and not
-        overriding them in every derived class, will hide one of
-        them. Later trying to override the same method, will generate
-        a new vtable slot, and lead to very hard to spot errors.
