Oooh, perfect, thank you.  Niko suggested something quite similar
today; having a 

trait HasGType {
    fn get_type() -> GType
}

and implementing it for all i32/bool/etc.  This is pretty much what the
StaticType trait does in that file.  I'll use it!

gnome-class lets you derive from C GObjects.

I *think* gtk-rs lets you create a wrapped/bound gobject if you just
have a pointer to it, correct?  If so, gnome-class lets you access your
parent instance or parent class, and get a pointer to it... could one
pass that pointer to gtk-rs and get a binding for your parent?

Am I thinking that you want to do

gobject_gen! {
    class MyWidget: GtkWidget {
        ... derive it ...
    }
}

and in your implementation of MyWidget, actually use gtk-rs's binding
for GtkWidget instead of calling gtk functions by hand?
