  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.
