* We'll be able to cast this to a RectObj or Widget for most uses,
* but XtIsRectObj will return False, so Motif won't mess with it.
* We'll still have to fake _XmConfigureObject() out to make it
* think that it is a rectobj for that one case...
* Or if _XmConfigureObject() is causing too many redraws, then
* we can write our own version that doesn't need to be faked out.
