    themingengine: don't hardcode white to draw insensitive labels shadow
    
    Use the background color instead.
    I think the optimal solution would be delegating the shadow rendering to
    the theme completely, and removing this in GtkThemingEngine, but for
    now, this simple fix makes the dark variant more usable.
