/* 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; 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_XXX. This file is included twice here; the first */
/* time to generate parsing callback functions, the second time to */
/* generate a table of keywords (with pointers to the associated */
/* callback functions). */
/* */
/* 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'. */
