Adding this could make it implementable now, if a class also made its own

    properties=>[Glib::ParamSpec->boolean('orientation')]

Not sure that's to be recommended though, if the glib interface stuff is going
to automatically create the interface properties later on.

Depends perhaps what the glib stuff is going to do if it finds the property in
question already exists.  You'd be inclined to make it an
error/warning/log/whatever, but I suppose it could quietly assume the subclass
knew what it was doing and omit interface properties already in the subclass
(and not in a superclass).  Would that be a bit painful?  One thing it might
allow though is the pspec=>,get=>,set=> style property creation dispatching to
individual handler funcs instead of GET_PROPERTY/SET_PROPERTY.

    properties => [ { pspec => Glib::ParamSpec->override
                               ('orientation',
                                
Gtk2::Orientable->find_property('orientation')),
                      get => \&_my_orient_get,
                      set => \&_my_orient_set,
                    } ]

Bit tedious to write as well as to implement maybe :-).
