    Handle another place where unknown coordinates were treated as offscreen
    
    Apparently (-1, -1, -1, -1) is being used to specify an undetermined
    bounding box. Therefore do not automatically treat an object with
    these coordinates as off-screen. This will hopefully solve the flat
    review failure seen with apps written in Gtk+ 3.24.24.
