On the client side, it is as you said, you'll need to make the request on
the GtkWindow's wl_surface.

On the server side, in the protocol implementation you will get a
wl_resource* surface_resource which corresponds to the wl_surface object.
You can then do `weston_surface *surface =
wl_resource_get_user_data(surface_resource);` to get the weston_surface. I
hope this helps.
