This creates an action column widget when the widget is rendered for the first time. The original approach was to create an image and render the buffered image onto the cell until the first mouse action triggered the creation of the real widget. This led to several rendering problems and triggered some strange ownership issues with crashes under certain situations. Followup a05b2ad9
