Werner Lemberg 72f5ff5bbb [autofit] Introduce `writing systems'.
This patch adds a new top level to the auto-hinter's script class
hierarchy.  It defines `writing systems' which can contain multiple
scripts.

For example, the `latin' writing system (in file `aflatin.c') is
able to support scripts like Latin, Cyrillic, Armenian, etc., which
can be handled similarly.

Scripts are now named using four-letter OpenType tags.

to...
(AF_WritingSystemClassRec): This new structure.  It holds pointers
to functions which can be shared among related scripts.

suzuki toshiya 084abf0469 [autofit] Add bluezones for CJK Ideographs.
To remove extremas of vertical strokes of CJK Ideographs at
low resolution and make the top and bottom horizontal stems
aligned, bluezones for CJK Ideographs are calculated from
sample glyphs.  At present, vertical bluezones (bluezones
to align vertical stems) are disabled by default.  For detail, see
