- *
- *
- * This is the new and improved Type 1 data loader for FreeType 2.
- * The old loader has several problems: it is slow, complex, difficult
- * to maintain, and contains incredible hacks to make it accept some
- * ill-formed Type 1 fonts without hiccup-ing. Moreover, about 5%
- * of the Type 1 fonts on my machine still aren't loaded correctly
- * by it.
- *
- * This version is much simpler, much faster and also easier to
- * read and maintain by a great order of magnitude. The idea behind
- * it is to _not_ try to read the Type 1 token stream with a state
- * machine (i.e. a Postscript-like interpreter) but rather to perform
- * simple pattern-matching.
- *
- * Indeed, nearly all data definitions follow a simple pattern
- * like :
- *
- * ..... /Field <data> ....
- *
- * where <data> can be a number, a boolean, a string, or an
- * array of numbers. There are a few exceptions, namely the
- * encoding, font name, charstrings and subrs and they are
- * handled with a special pattern-matching routine.
- *
- * All other common cases are handled very simply. The matching
- * rules are defined in the file "t1tokens.h" through the use
- * of several macros calls PARSE_XXXX
- *
- * This file is included twice here, the first time to generate
- * parsing callback functions, the second to generate a table
- * of keywords (with pointers to the associated callback).
- *
- * The function "parse_dict" simply scans *linearly* a given
- * dictionary (either the top-level or private one) and calls
- * the appropriate callback when it encounters an immediate
- * keyword.
- *
- * This is by far the fastest way one can find to parse and read
- * all data :-)
- *
- * This led to tremendous code size reduction. Note that later,
- * the glyph loader will also be _greatly_ simplified, and the
- * automatic hinter will replace the clumsy "t1hinter"..
