    * Passes through calls that represent image toolkit operations onto the
    * image toolkit.
    *
-   * By implementing this magic method, image operations are accessible directly
-   * from the Image object as if it were methods of \Drupal\Core\Image\Image.
-   * For example next calls can be performed on an Image object:
+   * This is a temporary solution to keep patches reviewable. The __call()
+   * method will be replaced in https://drupal.org/node/2073759 with a new
+   * interface method ImageInterface::apply(). An image operation will be
+   * performed as in the next example:
    * @code
    * $image = new Image($path, $toolkit);
-   * $image->scale(50, 100);
-   * $image->rotate(30);
+   * $image->apply('scale', array('width' => 50, 'height' => 100));
    * @endcode
+   * Also in https://drupal.org/node/2073759 operation arguments sent to toolkit
+   * will be moved to a keyed array, unifying the interface of toolkit
+   * operations.
+   *
+   * @todo Drop this in https://drupal.org/node/2073759 in favor of new apply().
