* @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.
