 * theme, so that icons can be looked up quickly. ThemedIcon does
 * not provide actual pixmaps for icons, just the icon names.
 * Ideally something like Gtk::IconTheme::choose_icon() should be used to
 * resolve the list of names so that fallback icons work nicely with
 * themes that inherit other themes.
