Arjan's answer is correct. I would emphasize (as he indicated)
that for a language binding it would be poor form if you added
the viewport automatically.

We used to do to this in GTK+, but this causes problems if
somebody does:

 gtk_container_add (GTK_CONTAINER (sw), some_widget);

and then tries to do:

 gtk_container_remove (GTK_CONTAINER (sw), some_widget);

Plus, maintaining consistancy between GTK+ and all language
bindings will help maintain the usefulness of tutorial
and reference documentation across language bindings.
