 * GtkIconLookupFlags:

 * @GTK_ICON_LOOKUP_FORCE_SVG: Return SVG icons, even if gdk-pixbuf

 *   doesn't support them.

 *   Cannot be used together with %GTK_ICON_LOOKUP_NO_SVG.

 * @GTK_ICON_LOOKUP_USE_BUILTIN: When passed to

 *   gtk_icon_theme_lookup_icon() includes builtin icons

 *   as well as files. For a builtin icon, gtk_icon_info_get_filename()

 *   returns %NULL and you need to call gtk_icon_info_get_builtin_pixbuf().

 * @GTK_ICON_LOOKUP_GENERIC_FALLBACK: Try to shorten icon name at '-'

 *   characters before looking at inherited themes. For more general

 *   fallback, see gtk_icon_theme_choose_icon(). Since 2.12.

 * @GTK_ICON_LOOKUP_FORCE_SIZE: Always return the icon scaled to the

 *   requested size. Since 2.14.

 *
