this corresponds to the Perl idiom of:

        $self->SUPER::size_request($requisition);

but you must be overriding the signal class closure in Perl as well, and
not just connect to the ::size-request signal (I don't know whether
you're already doing this, but it might be a hint)[1].

what you want to achieve, though, is better done by simply forcing the
size of your widget, and its eventual children, to the given requisition
- which is what the parent's implementation is doing anyway.

in fact, if your widget doesn't have any children, you shouldn't be
overriding the size-request signal closure at all.

[1] I wrote the equivalent code -- I did not test it, and on the top of
my head I don't remember if Gtk2::Widget allows you to override the size
requisition phase using Universal::SUPER.
