    layout: Fix regressions
    
    Commit 6b4f52462071dc9af5b8915afebc8bc340b49ca2 removed the layer checks
    _updateFullscreen ... this causes corruption when alt-tabbing out
    of a fullscreen window so restore the check.
    
    The commit also removed the screen sized check so we are no longer
    setting all monitors to fullscreen. Fix that as well by using
    window.is_screen_sized() to perform the check.
