    Fix clang error about type mismatch GtkWidget* != void* aka gpointer
    
    in the second argument and an extra ptr level in the first.
    (The declaration is
    g_atomic_pointer_compare_and_exchange(void* atomic, gpointer old,
                                          gpointer new)
    but that's wrong as it tests *atomic == old so atomic needs to be
    void**. But we were passing &gpointer* i.e. void***.)
