    view: add a shadow to the view when not showing tabs
    
    When we are showing tabs, the notebook will take care of drawing a
    border around the view.
    When there is only one view, since we disable tabs from the notebook,
    the view needs to draw a shadow instead, or we won't draw any shadow at
    all. In the past this wasn't a problem because the toolbar used to draw
    a stroke for us.
