    Only send property-change signals relevant for caching, absent listeners
    
    Previously, all property-change signals were passed on, regardless of any
    registered listeners, because some of them are used by libatspi to keep the
    cache up-to-date. However, gtk sends many notifications for property changes
    that would have no impact on libatspi's caching code, so we should not waste
    time building and sending D-Bus messages for them unless something is
    interested in the event.
