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.

New in Version 1.2 (2014-Oct-06)
--------------------------------

* It is now possible to control the hinting process at a very low level
  using a 'control instructions' file.  Right now, two modes are supported:

    - Adding segments and changing segment directions.

    - Applying delta exceptions.  Note that this doesn't really work in
      ClearType.

  Please see the documentation for a description and a small tutorial.

  In the TTY front-end, use option `--control-file` to load such a file.

* Support for input file watching in ttfautohintGUI: If the 'Watch Input
  File' box is checked, the program automatically regenerates the output
  file as soon as the input font or control instructions file gets modified.

  The idea is to dock ttfautohintGUI to your favourite font and text editor
  instead of adding a cheap text editor to ttfautohintGUI itself.

* With the new option `--fallback-stem-width` it is now possible to set a
  default stem width for all scripts that lack proper standard characters in
  the font.

* Add alias `--adjust-subglyphs` for option `--pre-hinting` to better
  describe its functionality.  The short form `-p` stays unchanged.

* New option `--ttfa-table` to add an SFNT table `TTFA` to the output font,
  containing an ASCII dump of all used ttfautohint parameters (including
  control instructions).  Right now, this is mainly for archiving purposes. 
  Forthcoming versions of ttfautohint will be able to re-use this data if a
  font gets re-processed.

* A harmless buglet was fixed that made the `glyf` table too large by one
  byte under some circumstances.

* A bug fix taken from FreeType, correcting a crash for unusual outlines.

* Better handling of TTC files.

* New library options `error-callback` and `error-callback-data` for
  improved diagnostics.  [No change in the front-ends except better error
  messages.]

* Many other, minor fixes and improvements.
