Yes.  There area  lot of objects in GTK+ / gtkmm that are
reference-counted, and we want to increment the reference instead of
copy them on assignment.  Therefore, we don't want to allow the user
to construct a raw object, we want a RefPtr which will handle all of
the referencing and dereferencing for us.
