   *                USER-SELECTABLE CONFIGURATION MACROS
   *
   * This file contains the default configuration macro definitions for a
   * standard build of the FreeType library.  There are three ways to use
   * this file to build project-specific versions of the library:
   *
   * - You can modify this file by hand, but this is not recommended in
   *   cases where you would like to build several versions of the library
   *   from a single source directory.
   *
   * - You can put a copy of this file in your build directory, more
   *   precisely in `$BUILD/freetype/config/ftoption.h`, where `$BUILD` is
   *   the name of a directory that is included _before_ the FreeType include
   *   path during compilation.
   *
   *   The default FreeType Makefiles and Jamfiles use the build directory
   *   `builds/<system>` by default, but you can easily change that for your
   *   own projects.
   *
   * - Copy the file <ft2build.h> to `$BUILD/ft2build.h` and modify it
   *   slightly to pre-define the macro `FT_CONFIG_OPTIONS_H` used to locate
   *   this file during the build.  For example,
   *
   *   ```
   *     #define FT_CONFIG_OPTIONS_H  <myftoptions.h>
   *     #include <freetype/config/ftheader.h>
   *   ```
   *
   *   will use `$BUILD/myftoptions.h` instead of this file for macro
   *   definitions.
   *
   *   Note also that you can similarly pre-define the macro
   *   `FT_CONFIG_MODULES_H` used to locate the file listing of the modules
   *   that are statically linked to the library at compile time.  By
   *   default, this file is `<freetype/config/ftmodule.h>`.
   *
   * We highly recommend using the third method whenever possible.

   * You have to undefine this configuration option on platforms that lack

   * technical overview on what this means.  See `ttinterp.h` for more
   * details on the LEAN option.
   *
   * There are three possible values.
   *
   * Value 1:
   *   This value is associated with the 'Infinality' moniker, contributed by
   *   an individual nicknamed Infinality with the goal of making TrueType
   *   fonts render better than on Windows.  A high amount of configurability
   *   and flexibility, down to rules for single glyphs in fonts, but also
   *   very slow.  Its experimental and slow nature and the original
   *   developer losing interest meant that this option was never enabled in
   *   default builds.
   *
   *   The corresponding interpreter version is v38.
   *
   * Value 2:
   *   The new default mode for the TrueType driver.  The Infinality code
   *   base was stripped to the bare minimum and all configurability removed
   *   in the name of speed and simplicity.  The configurability was mainly
   *   aimed at legacy fonts like 'Arial', 'Times New Roman', or 'Courier'.
   *   Legacy fonts are fonts that modify vertical stems to achieve clean
   *   black-and-white bitmaps.  The new mode focuses on applying a minimal
   *   set of rules to all fonts indiscriminately so that modern and web
   *   fonts render well while legacy fonts render okay.
   *
   *   The corresponding interpreter version is v40.
   *
   * Value 3:
   *   Compile both, making both v38 and v40 available (the latter is the
   *   default).
   *
   * By undefining these, you get rendering behavior like on Windows without
   * ClearType, i.e., Windows XP without ClearType enabled and Win9x
   * (interpreter version v35).  Or not, depending on how much hinting blood
   * and testing tears the font designer put into a given font.  If you
   * define one or both subpixel hinting options, you can switch between
   * between v35 and the ones you define (using `FT_Property_Set`).

   * This option requires `TT_CONFIG_OPTION_BYTECODE_INTERPRETER` to be
