  // If this is a new entity, populate the field with the right default values.
  // This happens early so even fields later hidden with #access get those values.
  // We should only add default values to new entities, to avoid over-writing
  // a value that has already been set. This means we can't just check to see
  // if $items is empty, because it might have been set that way on purpose.
  // @see date_field_widget_properties_alter() where we flagged if this is a new entity.

  // We check !isset($items[$delta]['value']) because entity translation may create
  // a new translation entity for an existing entity and we don't want to clobber
  // values that were already set in that case.
  // @see http://drupal.org/node/1478848.
