    window: fix initial shadow width for maximized/fullscreen windows
    
    To calculate the shadow width, we look at the value of priv->fullscreen
    and priv->maximized.
    Those fields will have the actual value only after GTK receives back a
    window state event though, so they will be wrong in _realize(). Look at
    priv->fullscreen_initially and priv->maximize_initially too, to avoid
    the size changing right after realize, which would make the window
    flicker if maximized at startup.
