function theme_icon($variables) {
  $output = '';
  $bundle = $variables['bundle'];
  $icon = $variables['icon'];
  if (!empty($bundle) && !empty($icon)) {

    // Render the icon.
    // @todo This should be a render array, but converting the variables to
    // render array properties is needed to do that and this is proxying them.
    // @FIXME
    // theme() has been renamed to _theme() and should NEVER be called directly.
    // Calling _theme() directly can alter the expected output and potentially
    // introduce security issues (see https://www.drupal.org/node/2195739). You
    // should use renderable arrays instead.
    //
    //
    // @see https://www.drupal.org/node/2195739
    // $output = theme('icon_' . $bundle['render'], $variables);
    // Wrap icon, if necessary.
