#NSOwner; if the #NSOwner does not respond to that
method, it will try windowDelegate; if the #NSOwner
does not to respond to it either, it will try
_getWindowDelegate, and then _windowDelegate; if the
#NSOwner still does not respond to those methods, it will

_windowDelegate, if any, and failing that, the instance variable
windowDelegate. If all else fails, it will call the method
handleQueryWithUnboundKey: (which by default
usually raises an exception).
