From wp-admin/includes/meta-boxes.php. Fires after all built-in meta boxes have been added. Custom metaboxes may be enqueued here. Note that the documentation for this hook (and for the corresponding 'add_meta_boxes_<SCREEN_ID>' hook) suggest that a post type will be supplied for the first parameter, and and an instance of WP_Post will be supplied as the second parameter. We are not doing that here, however WordPress itself also deviates from this in respect of comments and (though now less relevant) links.
