Renders an icon using gtk_style_render_icon(). In most cases, gtk_widget_render_icon() is better, since it automatically provides most of the arguments from the current widget settings. This function never returns %NULL; if the icon can’t be rendered (perhaps because an image file fails to load), a default "missing image" icon will be returned instead.
