    list-view: Use coordinates passed by gesture
    
    We have coordinates right there in the gesture ::release signal, but
    are still getting coordinates from GdkEvent.
    
    This is because gtk_tree_view_get_path_at_pos() requires bin_window
    coordinates, which happened to be what the GdkEvent coordinates are
    (because bin_window is the event's GdkWindow).
    
    In order to use gesture coordinates, we need to translate them into
    bin coordinates.
