* @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.
