    scrolledwindow: Don't displace invalidation by the widget allocation
    
    This was left unmodified when GtkScrolledWindow was made a windowed widget.
    Displacing here by the widget allocation is not necessary anymore, since
    we are invalidating the window set at these coordinates.
    
    This patch is a simplification of a previous one by Timm Bäder.
