    fishbowl: Remove visibility handling
    
    First, almost all widgets are either visible and mapped, or visible and
    unmapped because they are !child_visible. In both cases, we do care
    about the size. If they are indeed invisible, gtk_widget_measure() will
    take care of that by returning all 0.
    
    And gtk_widget_unparent() already queues a resize on the parent if
    necessary, so that is unneeded as well.
