/**************************************************************************
*
* 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.

*
* In particular, it modifies the bytecode interpreter to interpret (or
* not) instructions in a certain way so that all TrueType fonts look
* like they do in a Windows ClearType (DirectWrite) environment. See
* [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
* switch between between v35 and the ones you define.
*
* This option requires TT_CONFIG_OPTION_BYTECODE_INTERPRETER to be
* defined.

* Compile autofit module with warp hinting. The idea of the warping
* code is to slightly scale and shift a glyph within a single dimension
* so that as much of its segments are aligned (more or less) on the
* grid. To find out the optimal scaling and shifting value, various
* parameter combinations are tried and scored.
*
* This experimental option is active only if the rendering mode is
* FT_RENDER_MODE_LIGHT; you can switch warping on and off with the
* `warping' property of the auto-hinter (see file `ftautoh.h' for more
* information; by default it is switched off).
