  18   * Inserts the URL of a file resource customizable by themes

  19   *

  20   * This plug-in works like the {@link smarty_compiler_xoAppUrl() xoAppUrl} plug-in,

  21   * except that it is intended to generate the URL of resource files customizable by

  22   * themes.

  23   * 

  24   * Here the current theme is asked to check if a custom version of the requested file exists, and

  25   * if one is found its URL is returned. Otherwise, the request will be passed to the

  26   * theme parents one by one. Ultimately, if no custom version has been found, the resource

  27   * default URL location will be returned.

  28   * 

  29   * <b>Note:</b> the themes inheritance system can generate many filesystem accesses depending

  30   * on your themes configuration. Because of this, the use of the dynamic syntax with this plug-in

  31   * is not possible right now.
