    /* Previous versions of DD4hep output parameters that required more complex conversion

     * "dimensions" function.  If the more complex conversion is ever needed again, the git history
     * of this file from before 2019-11-25 has code for converting from the internal DD4hep parameters
     * for a TruncatedTube to the eight parameters used by CMS.
     * There is also example code for checking the parameters of the TGeoCompositeShape.
