Renders an icon using gtk_render_icon_pixbuf(). In most cases,
Widget.renderIconPixbuf 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.
