        Configure and return the renderer based on the passed in components. The value is typically set from messaging the graph with convertValueToString.
        Specified by:
        getRendererComponent in interface CellViewRenderer
        Parameters:
        graph - the graph that that defines the rendering context.
        view - the cell view that should be rendered.
        sel - whether the object is selected.
        focus - whether the object has the focus.
        preview - whether we are drawing a preview.
        Returns:
        the component used to render the value.
