    overview: Don't hide the overview on startup when re-laying it out
    
    In a similar fashion to what we did in EOS 3.1, split the relayout()
    method in two, so that we can force a relayout on initialization of
    the overview without forcing a call to hide(), which we don't want
    to do since our shell starts right in overview mode.
