    widget: make sure to check all children for allocation needs
    
    GtkWidget uses gtk_container_foreach() to iterate over children and
    check whether they need their allocation reset.
    However, that leaves out internal children, such as scrollbars of a
    GtkScrolledWindow. Use gtk_container_forall() instead.
