   *
   *                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.
   *

   * [1] for a technical overview on what this means.  See `ttinterp.h'
   * for more details on the LEAN option.
   *
   * There are three options.
   *
   * 1. This option 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.
   *
   * 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.
   *
   * 3. Compile both.
   *
   * 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
