 * @GTK_IMAGE_GICON: the widget contains a `GIcon`
 * @GTK_IMAGE_PAINTABLE: the widget contains a `GdkPaintable`
 *
 * Describes the image data representation used by a [class@Gtk.Image].
 *
 * If you want to get the image from the widget, you can only get the
 * currently-stored representation; for instance, if the gtk_image_get_storage_type()
 * returns %GTK_IMAGE_PAINTABLE, then you can call gtk_image_get_paintable().
 *
 * For empty images, you can request any storage type (call any of the "get"
 * functions), but they will all return %NULL values.
