This project provides a library which takes a TrueType font as the input,
remove its bytecode instructions (if any), and return a new font where all
glyphs are bytecode hinted using the information given by FreeType's
autohinting module.  The idea is to provide the excellent quality of the
autohinter on platforms which don't use FreeType.

The library has a single API function, `TTF_autohint'; see
`lib/ttfautohint.h' for a detailed description.  Note that the library
itself won't get installed currently.

A command-line interface to the library is the `ttfautohint' program; after
compilation and installation, say

  ttfautohint --help

for usage information, or say

  man ttfautohint

to read its manual page.

A GUI to the library is `ttfautohintGUI'; it uses the Qt4 framework.  The
compilation of this application can be disabled with the `--without-qt'
configuration option.


Version 1.5 (2016-Jan-24)

* Support for Khmer, Myanmar, and Bengali scripts.

* Improved Devanagari hinting.

* ttfautohintGUI can now be compiled with Qt5.

* Bug fix: Too many delta control instructions for a single glyph caused
  a bytecode stack overflow, making the MS rasterizer ignore all hinting
  instructions for this glyph.

* Bug fix: Don't create multiple `TTFA` tables in font.

* Bug fix: Under certain circumstances, glyph indices used in Indic features
  were incorrectly assigned to the default script.
