 * @drawable_ID: Pointer to the drawable_ID.
 * @format_name: The (short) name of the image_format (e.g. JPEG or GIF).
 * @capabilities: What can the image_format do?
 *
 * Takes an image and a drawable to be saved together with a
 * description of the capabilities of the image_format. If the
 * type of image doesn't match the capabilities of the format
 * a dialog is opened that informs the user that the image has
 * to be exported and offers to do the necessary conversions.
 *
 * If the user chooses to export the image, a copy is created.
 * This copy is then converted, the image_ID and drawable_ID
 * are changed to point to the new image and the procedure returns
 * GIMP_EXPORT_EXPORT. The save_plugin has to take care of deleting the
 * created image using gimp_image_delete() when it has saved it.
 *
 * If the user chooses to Ignore the export problem, the image_ID
 * and drawable_ID is not altered, GIMP_EXPORT_IGNORE is returned and
 * the save_plugin should try to save the original image. If the
 * user chooses Cancel, GIMP_EXPORT_CANCEL is returned and the
 * save_plugin should quit itself with status %GIMP_PDB_CANCEL.
 *
 * If @format_name is NULL, no dialogs will be shown and this function
 * will behave as if the user clicked on the 'Export' button, if a
 * dialog would have been shown.
