  Completely revised Type 42 parser.  It now handles both fonts
  produced with ttftot42 (tested version 0.3.1) and
  TrueTypeToType42.ps (tested version May 2001; it is necessary to
  fix the broken header comment to be `%!PS-TrueTypeFont...').
  
  * src/type42/t42objs.c (T42_GlyphSlot_Load): Change fourth
  parameter to `FT_UInt'.
  * src/type42/t42objs.h: Updated.
  
  * src/type42/t42parse.h (T42_ParserRec): Change type of `in_memory'
  to FT_Bool.
  (T42_Loader): Change type of `num_chars' and `num_glyphs' to
  FT_UInt.
  Add `swap_table' element.
  * src/type42/t42parse.c (T42_KEYWORD_COUNT, T1_ToFixed,
  T1_ToCoordArray, T1_ToTokenArray): Removed.
  (T1_ToBytes): New macro.
  (t42_is_alpha, t42_hexval): Removed.
  (t42_is_space): Handle `\0'.
  (t42_parse_encoding): Updated to use new PostScript parser routines
  from psaux.
  Handle `/Encoding [ ... ]' also.
  (T42_Load_Status): New enumeration.
  (t42_parse_sfnts): Updated to use new PostScript parser routines
  from psaux.
  (t42_parse_charstrings): Updated to use new PostScript parser
  routines from psaux.
  Handle `/CharStrings << ... >>' also.
  Don't expect that /.notdef is the first element in dictionary.  Copy
  code from type1 module to handle this.
  (t42_parse_dict): Updated to use new PostScript parser routines
  from psaux.
  Remove code for synthetic fonts (which can't occur in Type 42
  fonts).
  (t42_loader_done): Release `swap_table'.
  
  * src/psaux/psobjs.c (skip_string): Increase `cur' properly.
  
  * src/type1/t1load.c (parse_charstrings): Make test for `.notdef'
  faster.
