*
* 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 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.

*
* 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`).
