// Setup the interface map so that an nsIXFormsDOMEvent can be QI'ed to
// nsIDOMEvent, nsIDOMNSEvent, nsIPrivateDOMEvent, and nsISupports.
//
// nsISupports is ambiguous because all of the interfaces inherit from
// nsISupports. NS_INTERFACE_MAP_ENTRY_AMBIGOUS will cast to the
// nsISupports of nsXFormsDOMEvent.
//
// nsXFormsDOMEvent contains an nsIDOMEvent (mInner) and nsIDOMEvent
// implements nsIDOMNSEvent and nsIPrivateDOMEvent. The event dispatcher
// will QI to those interfaces. We use NS_INTERFACE_MAP_END_AGGREGATED to
// forward QIs for those interfaces to mInner.
