FreeType 2  is a software  font engine that  is designed to  be small,
efficient,  highly   customizable,  and  portable   while  capable  of
producing high-quality output (glyph images) of most vector and bitmap
font formats.

Note that  FreeType 2 is  a font service  and doesn't provide  APIs to
perform higher-level features, like text layout or graphics processing
(e.g.,  colored  text  rendering,  'hollowing',  etc.).   However,  it
greatly simplifies these tasks by providing a simple, easy to use, and
uniform interface to access the content of font files.

FreeType  2  is  released  under  two open-source  licenses:  our  own
BSD-like FreeType  License and the  GPL.  It can  thus be used  by any
kind of projects, be they proprietary or not.

You  can use  a  `.sig` file  to verify  that  the corresponding  file
(without the  `.sig` suffix)  is intact.  First,  be sure  to download
both  the `.sig`  file and  the  corresponding archive.   Then, run  a
command like this:

  gpg --verify freetype-2.13.0.tar.gz.sig

If that command fails because you  don't have the required public key,
execute

  gpg --keyserver pgp.mit.edu --recv-keys BE6C3AAC63AD8E3F

to import it, then rerun the `gpg --verify` command.

CHANGES BETWEEN 2.12.1 and 2.13.0 (2023-Feb-09)

  I. IMPORTANT CHANGES

  - The demo program `ftinspect` has  been completely updated and much
    enhanced.  It now  combines the functionality of  almost all other
    graphical FreeType  demo programs into a  single application based
    on the Qt framework.  This was Charlie Jiang's GSoC 2022 project.

  - The 'COLR' v1 API is now considered as stable.

  III. MISCELLANEOUS

  - For  OpenType  Variable Fonts,  `avar`  table  format 2.0  is  now
    supported.  The code was contributed by Behdad Esfahbod.

    Note that this is an extension supported on recent Apple platforms
    and by HarfBuzz, but not yet in the OpenType standard!  See

      https://github.com/harfbuzz/boring-expansion-spec/blob/main/avar2.md

    for the specification.  To deactivate it, define the configuration
    macro 'TT_CONFIG_OPTION_NO_BORING_EXPANSION'.

  - A new API  `FT_GlyphSlot_Slant` to slant a glyph by  a given angle
    has been added.   Note that this function is  part of `ftsynth.h`,
    which is still considered to be in alpha stage.

  - TrueType interpreter version 38  (also known as 'Infinality') that
    was first introduced about 10 years  ago in FreeType 2.4.11 is now
    deprecated and slated to be removed in the next version.  TrueType
    interpreter version 40 has been FreeType's default version for six
    years now and provides an excellent alternative.  This is the last
    FreeType     version     with    TT_INTERPRETER_VERSION_38     and
    TT_INTERPRETER_VERSION_40 treated differently.

  - The  only  referenced  but never  documented  configuration  macro
    `FT_CONFIG_OPTION_NO_GLYPH_NAMES` has been removed.

  - The `ftbench` demo  program got a new command line  option `-e` to
    set a charmap index.

  - Specifying  a point  size is  now optional  for the  demo programs
    `ftgrid`, `ftmulti`,  `ftstring`, and  `ftview`.  If not  given, a
    default size is used.

  - For  `ftgrid`,  `ftstring`, and  `ftview`,  option  `-e` now  also
    accepts a numeric value to set a charmap index.

  - In  `ftstring`, it  is  now  possible to  set  the displayed  text
    interactively by pressing the 'Enter' key.

  - `ftmulti` can now handle up to 16 design axes.

  - To  avoid  reserved identifiers  that  are  globally defined,  the
    auto-hinter  debugging   macros  (which  are  only   available  if
    `FT_DEBUG_AUTOFIT` is defined)

    ```
    _af_debug_disable_horz_hints
    _af_debug_disable_vert_hints
    _af_debug_disable_blue_hints
    _af_debug_hints
    ```

    have been renamed to

    ```
    af_debug_disable_horz_hints_
    af_debug_disable_vert_hints_
    af_debug_disable_blue_hints_
    af_debug_hints_
    ```
