    actor: Fix get_paint_volume() default implementation
    
    Providing a default get_paint_volume() that takes into account the
    children of an actor was a goal of the whole First Apocalypse; if we
    make all the containers rely on it, and yet we return a FALSE value
    (meaning: we don't have a valid paint volume) even when we do have it,
    then we are going to break the whole machinery, though.
