Unfortunately, that seems to be intentional.  Looking at 
<http://developer.gnome.org/gtk3/stable/GtkImage.html#gtk-image-new-from-stock>, 
the "size" parameter has a "[type int]" annotation.  The Perl bindings 
thus see a plain integer parameter, and the enum string magic is never 
invoked.  The reason for this annotation is explained in 
<https://bugzilla.gnome.org/show_bug.cgi?id=604895>.

I haven't figured out how to deal with this.  Suggestions welcome. 
Maybe some facility in Glib::Object::Introspection that lets binding 
authors mark certain parameters as being "extendable enums", for which 
enum strings and integers are accepted.
