  // Fields for cover image.
  //
  // These use a combination of code and separate queries to get a cover node.
  // This makes them more powerful that using the relationship cover node,
  // as we can consider child galleries recursively rather than just
  // flattening all descendant galleries.
  // We can also do complex things such as grab the top-most node from the
  // gallery according to how the view for that gallery sorts them.
  // The downside however is that without a relationship, the fields here are
  // all you've got.
  // To add more fields, define them on term_data and optionally add handlers.
  // See image_gallery_handler_field_gallery_cover for more information.
