   *
   * @Description:
   *   A PS_ParserRec is an object used to parse a Type 1 fonts very
   *   quickly.
   *
   * @Fields:
   *   root ::
   *     The root parser.
   *
   *   stream ::
   *     The current input stream.
   *
   *   base_dict ::
   *     A pointer to the top-level dictionary.
   *
   *   base_len ::
   *     The length in bytes of the top dictionary.
   *
   *   private_dict ::
   *     A pointer to the private dictionary.
   *
   *   private_len ::
   *     The length in bytes of the private dictionary.
   *
   *   in_pfb ::
   *     A boolean.  Indicates that we are handling a PFB
   *     file.
   *
   *   in_memory ::
   *     A boolean.  Indicates a memory-based stream.
   *
   *   single_block ::
   *     A boolean.  Indicates that the private dictionary
   *     is stored in lieu of the base dictionary.
