   * @Struct:
   *   CID_Parser
   *
   * @Description:
   *   A CID_Parser is an object used to parse a Type 1 fonts very
   *   quickly.
   *
   * @Fields:
   *   root ::
   *     The root PS_ParserRec fields.
   *
   *   stream ::
   *     The current input stream.
   *
   *   postscript ::
   *     A pointer to the data to be parsed.
   *
   *   postscript_len ::
   *     The length of the data to be parsed.
   *
   *   data_offset ::
   *     The start position of the binary data (i.e., the
   *     end of the data to be parsed.
   *
   *   binary_length ::
   *     The length of the data after the `StartData'
   *     command if the data format is hexadecimal.
   *
   *   cid ::
   *     A structure which holds the information about
   *     the current font.
   *
   *   num_dict ::
   *     The number of font dictionaries.
