/**
 * Plugin implementation of the 'cloudinary_image' formatter.
 *
 * This formatter is useful if you want to display an original image with
 * custom applied transformation from cloudinary media library (if any).
 * No image style applied, but we take into accounts breakpoints settings.
 *
 * @FieldFormatter(
 *   id = "cloudinary_image",
 *   label = @Translation("Cloudinary image (DEPRECATED)"),
 *   field_types = {
 *     "image",
 *   }
 * )
 *
 * @deprecated in cloudinary:3.0.0 and is removed from cloudinary:4.0.0. Use
 *   core image field formatter.
 *
 * @see https://www.drupal.org/project/cloudinary/issues/3314722
