The old style-enum won't let us change this, in gtkmm 3,
Gtk::RESPONSE_OK
into this, in gtkmm 4:
Gtk::Dialog::Response::OK
without also polluting the API with this
Gtk::Dialog::OK

Using an old-style enum would let us have this:
Gtk::Dialog::RESPONSE_OK,
(and Gtk::Dialog::Response::RESPONSE_OK)
which is still an improvement, but not quite as nice.
