/**
* Inserts the URL of a file resource customizable by themes
*
* This plug-in works like the {@link smarty_compiler_xoAppUrl() xoAppUrl} plug-in,
* except that it is intended to generate the URL of resource files customizable by
* themes.
*
* Here the current theme is asked to check if a custom version of the requested file exists, and
* if one is found its URL is returned. Otherwise, the request will be passed to the
* theme parents one by one. Ultimately, if no custom version has been found, the resource
* default URL location will be returned.
*
* <b>Note:</b> the themes inheritance system can generate many filesystem accesses depending
* on your themes configuration. Because of this, the use of the dynamic syntax with this plug-in
* is not possible right now.
* @param $argStr
* @param $smarty
* @return string
