[gnome-shell/overview-relayout: 4/14] linear-view: Remove shadows when zoomed out

    linear-view: Remove shadows when zoomed out
    
    Overlaying inactive workspaces with a gradient to fade out the actors
    does no longer work when re-using the normal desktop background. If
    we keep the current DND behavior, we probably want to implement a real
    fade effect - for now, just remove the visually disruptive shadows.
