    Fixed extended layout implementors to not call ->get_desired_size() directly
    
    Getting the desired size of a GtkWidget must always be done with
    gtk_widget_get_desired_size() and never with
    gtk_extended_layout_get_desired_size() directly as the former passes
    through size group logic and updates the widget->requisition cache.
