    widget: Allow invisible toplevels to do sizing operations
    
    This is a quickfix to keep things working.
    
    It turns out GtkWindow assumes it can do sizing operations while not
    being visible, or while in the process of show()ing/hide()ing itself.
    And commit b495ce54 broke these operations.
    
    Figuring this properly requires some more thinking and restructuring on
    my part, so for now we relax the requirement of visiblility enough for
    these things to start working again.
