    st/scroll-view: Don't queue redraw in update_fade_effect()
    
    ClutterEffects are responsible for queueing redraws when their
    properties change (and StScrollViewFade is a good citizen already), also
    Clutter itself should queue a redraw when adding/removing an effect.
    
    Users of Clutter should never have to queue redraws themselves (unless
    they're implementing a custom ClutterEffect or ClutterContent), so don't
    queue a redraw here.
