-   *
-   * @description:
-   *   *Experimental* *only*
-   *
-   *   The auto-hinter provides various script modules to hint glyphs.
-   *   Examples of supported scripts are Latin or CJK.  Before a glyph is
-   *   auto-hinted, the Unicode character map of the font gets examined, and
-   *   the script is then determined based on Unicode character ranges, see
-   *   below.
-   *
-   *   OpenType fonts, however, often provide much more glyphs than
-   *   character codes (small caps, superscripts, ligatures, swashes, etc.),
-   *   to be controlled by so-called `features'.  Handling OpenType features
-   *   can be quite complicated and thus needs a separate library on top of
-   *   FreeType.
-   *
-   *   The mapping between glyph indices and scripts (in the auto-hinter
-   *   sense, see the @FT_AUTOHINTER_SCRIPT_XXX values) is stored as an
-   *   array with `num_glyphs' elements, as found in the font's @FT_Face
-   *   structure.  The `glyph-to-script-map' property returns a pointer to
-   *   this array, which can be modified as needed.  Note that the
-   *   modification should happen before the first glyph gets processed by
-   *   the auto-hinter so that the global analysis of the font shapes
-   *   actually uses the modified mapping.
-   *
-   *   The following example code demonstrates how to access it (omitting
-   *   the error handling).
-   *
-   *   {
-   *     FT_Library                library;
-   *     FT_Face                   face;
-   *     FT_Prop_GlyphToScriptMap  prop;

-   *     FT_Init_FreeType( &library );
-   *     FT_New_Face( library, "foo.ttf", 0, &face );

-   *     prop.face = face;
-   *
-   *     FT_Property_Get( library, "autofitter",
-   *                               "glyph-to-script-map", &prop );

-   *   warping
-   *
-   * @description:
-   *   *Experimental* *only*
-   *
-   *   If FreeType gets compiled with option AF_CONFIG_OPTION_USE_WARPER to
-   *   activate the warp hinting code in the auto-hinter, this property
-   *   switches warping on and off.
-   *
-   *   Warping only works in `normal' auto-hinting mode replacing it.
-   *   The idea of the code is to slightly scale and shift a glyph along
-   *   the non-hinted dimension (which is usually the horizontal axis) so
-   *   that as much of its segments are aligned (more or less) to the grid.
-   *   To find out a glyph's optimal scaling and shifting value, various
-   *   parameter combinations are tried and scored.
-   *
-   *   By default, warping is off.  The example below shows how to switch on
-   *   warping (omitting the error handling).
-   *
-   *   {
-   *     FT_Library  library;
-   *     FT_Bool     warping = 1;
-   *
-   *

-   *   }
-   *
-   * @note:
-   *   This property can be used with @FT_Property_Get also.
-   *
-   *   This property can be set via the `FREETYPE_PROPERTIES' environment
-   *   variable (using values 1 and 0 for `on' and `off', respectively).
-   *
-   *   The warping code can also change advance widths.  Have a look at the
-   *   `lsb_delta' and `rsb_delta' fields in the @FT_GlyphSlotRec structure
-   *   for details on improving inter-glyph distances while rendering.
-   *
-   *   Since warping is a global property of the auto-hinter it is best to
-   *   change its value before rendering any face.  Otherwise, you should
-   *   reload all faces that get auto-hinted in `normal' hinting mode.

-   *   *Experimental* *only*, *requires* *linear* *alpha* *blending* *and*
-   *   *gamma* *correction*
-   *
-   *   Stem darkening emboldens glyphs at smaller sizes to make them more
-   *   readable on common low-DPI screens when using linear alpha blending
-   *   and gamma correction, see @FT_Render_Glyph.  When not using linear
-   *   alpha blending and gamma correction, glyphs will appear heavy and
-   *   fuzzy!
-   *
-   *   Gamma correction essentially lightens fonts since shades of grey are
-   *   shifted to higher pixel values (=~higher brightness) to match the
-   *   original intention to the reality of our screens.  The side-effect is
-   *   that glyphs `thin out'.  Mac OS~X and Adobe's proprietary font
-   *   rendering library implement a counter-measure: stem darkening at
-   *   smaller sizes where shades of gray dominate.  By emboldening a glyph
-   *   slightly in relation to its pixel size, individual pixels get higher
-   *   coverage of filled-in outlines and are therefore `blacker'.  This
-   *   counteracts the `thinning out' of glyphs, making text remain readable
-   *   at smaller sizes.  All glyphs that pass through the auto-hinter will
-   *   be emboldened unless this property is set to TRUE.
-   *
-   *   See the description of the CFF driver for algorithmic details.  Total
-   *   consistency with the CFF driver is currently not achieved because the
-   *   emboldening method differs and glyphs must be scaled down on the
-   *   Y-axis to keep outline points inside their precomputed blue zones.
-   *   The smaller the size (especially 9ppem and down), the higher the loss
-   *   of emboldening versus the CFF driver.
-   *
-   *   This property can be set via the `FREETYPE_PROPERTIES' environment
-   *   variable similar to the CFF driver.  It can also be set per face

+   *   Note that none of the functions changes the bitmap's 'flow' (as
+   *   indicated by the sign of the `pitch` field in @FT_Bitmap).
+   *
+   *   To set the flow, assign an appropriate positive or negative value to
+   *   the `pitch` field of the target @FT_Bitmap object after calling
+   *   @FT_Bitmap_Init but before calling any of the other functions
+   *   described here.

-   *
-   * @title:
-   *   The CFF driver
-   *
-   * @abstract:
-   *   Controlling the CFF driver module.
-   *
-   * @description:
-   *   While FreeType's CFF driver doesn't expose API functions by itself,
-   *   it is possible to control its behaviour with @FT_Property_Set and
-   *   @FT_Property_Get.  The list below gives the available properties
-   *   together with the necessary macros and structures.
-   *
-   *   The CFF driver's module name is `cff'.
-   *
-   *   *Hinting* *and* *antialiasing* *principles* *of* *the* *new* *engine*
-   *
-   *   The rasterizer is positioning horizontal features (e.g., ascender
-   *   height & x-height, or crossbars) on the pixel grid and minimizing the
-   *   amount of antialiasing applied to them, while placing vertical
-   *   features (vertical stems) on the pixel grid without hinting, thus
-   *   representing the stem position and weight accurately.  Sometimes the
-   *   vertical stems may be only partially black.  In this context,
-   *   `antialiasing' means that stems are not positioned exactly on pixel
-   *   borders, causing a fuzzy appearance.
-   *
-   *   There are two principles behind this approach.
-   *
-   *   1) No hinting in the horizontal direction: Unlike `superhinted'
-   *   TrueType, which changes glyph widths to accommodate regular
-   *   inter-glyph spacing, Adobe's approach is `faithful to the design' in
-   *   representing both the glyph width and the inter-glyph spacing
-   *   designed for the font.  This makes the screen display as close as it
-   *   can be to the result one would get with infinite resolution, while
-   *   preserving what is considered the key characteristics of each glyph.
-   *   Note that the distances between unhinted and grid-fitted positions at
-   *   small sizes are comparable to kerning values and thus would be
-   *   noticeable (and distracting) while reading if hinting were applied.
-   *
-   *   One of the reasons to not hint horizontally is antialiasing for LCD
-   *   screens: The pixel geometry of modern displays supplies three
-   *   vertical sub-pixels as the eye moves horizontally across each visible
-   *   pixel.  On devices where we can be certain this characteristic is
-   *   present a rasterizer can take advantage of the sub-pixels to add
-   *   increments of weight.  In Western writing systems this turns out to
-   *   be the more critical direction anyway; the weights and spacing of
-   *   vertical stems (see above) are central to Armenian, Cyrillic, Greek,
-   *   and Latin type designs.  Even when the rasterizer uses greyscale
-   *   antialiasing instead of color (a necessary compromise when one
-   *   doesn't know the screen characteristics), the unhinted vertical
-   *   features preserve the design's weight and spacing much better than
-   *   aliased type would.
-   *
-   *   2) Alignment in the vertical direction: Weights and spacing along the
-   *   y~axis are less critical; what is much more important is the visual
-   *   alignment of related features (like cap-height and x-height).  The
-   *   sense of alignment for these is enhanced by the sharpness of grid-fit
-   *   edges, while the cruder vertical resolution (full pixels instead of
-   *   1/3 pixels) is less of a problem.
-   *
-   *   On the technical side, horizontal alignment zones for ascender,

-   *
-   *   The default engine is `freetype' if CFF_CONFIG_OPTION_OLD_ENGINE is
-   *   defined, and `adobe' otherwise.
-   *
-   *   The following example code demonstrates how to select Adobe's hinting
-   *   engine (omitting the error handling).

-   *   By default, the Adobe CFF engine darkens stems as follows (if the
-   *   `no-stem-darkening' property isn't set):
-   *
-   *   {
-   *     stem width <= 0.5px:   darkening amount = 0.4px
-   *     stem width  = 1px:     darkening amount = 0.275px

-   *     stem width >= 2.333px: darkening amount = 0px
-   *   }
-   *
-   *   and piecewise linear in-between.  At configuration time, these four
-   *   control points can be set with the macro
-   *   `CFF_CONFIG_OPTION_DARKENING_PARAMETERS'.  At runtime, the control
-   *   points can be changed using the `darkening-parameters' property, as
-   *   the following example demonstrates.
-   *
-   *   {
-   *     FT_Library  library;
-   *     FT_Int      darken_params[8] = {  500, 300,   // x1, y1

-   *   }
-   *
-   *   The x~values give the stem width, and the y~values the darkening
-   *   amount.  The unit is 1000th of pixels.  All coordinate values must be
-   *   positive; the x~values must be monotonically increasing; the
-   *   y~values must be monotonically decreasing and smaller than or
-   *   equal to 500 (corresponding to half a pixel); the slope of each
-   *   linear piece must be shallower than -1 (e.g., -.4).
-   *
-   * @note:
-   *   This property can be used with @FT_Property_Get also.
-   *
-   *   This property can be set via the `FREETYPE_PROPERTIES' environment

+   * @title:
+   *   Error Enumerations
+   *
+   * @abstract:
+   *   How to handle errors and error strings.
+   *
+   * @description:
+   *   The header file `fterrors.h` (which is automatically included by
+   *   `freetype.h` defines the handling of FreeType's enumeration
+   *   constants.  It can also be used to generate error message strings
+   *   with a small macro trick explained below.
+   *
+   *   **Error Formats**
+   *
+   *   The configuration macro `FT_CONFIG_OPTION_USE_MODULE_ERRORS` can be
+   *   defined in `ftoption.h` in order to make the higher byte indicate the
+   *   module where the error has happened (this is not compatible with
+   *   standard builds of FreeType~2, however).  See the file `ftmoderr.h`
+   *   for more details.
+   *
+   *   **Error Message Strings**
+   *
+   *   Error definitions are set up with special macros that allow client
+   *   applications to build a table of error message strings.  The strings
+   *   are not included in a normal build of FreeType~2 to save space (most
+   *   client applications do not use them).
+   *
+   *   To do so, you have to define the following macros before including
+   *   this file.
+   *
+   *   ```
+   *     FT_ERROR_START_LIST
+   *   ```
+   *
+   *   This macro is called before anything else to define the start of the
+   *   error list.  It is followed by several `FT_ERROR_DEF` calls.
+   *
+   *   ```
+   *     FT_ERROR_DEF( e, v, s )
+   *   ```
+   *
+   *   This macro is called to define one single error.  'e' is the error
+   *   code identifier (e.g., `Invalid_Argument`), 'v' is the error's
+   *   numerical value, and 's' is the corresponding error string.
+   *
+   *   ```
+   *     FT_ERROR_END_LIST
+   *   ```
+   *
+   *   This macro ends the list.
+   *
+   *   Additionally, you have to undefine `FTERRORS_H_` before #including
+   *   this file.
+   *
+   *   Here is a simple example.
+   *
+   *   ```
+   *     #undef FTERRORS_H_
+   *     #define FT_ERRORDEF( e, v, s )  { e, s },
+   *     #define FT_ERROR_START_LIST     {
+   *     #define FT_ERROR_END_LIST       { 0, NULL } };
+   *
+   *     const struct
+   *     {
+   *       int          err_code;
+   *       const char*  err_msg;
+   *     } ft_errors[] =
+   *
+   *     #include FT_ERRORS_H
+   *   ```
+   *
+   *   An alternative to using an array is a switch statement.
+   *
+   *   ```
+   *     #undef FTERRORS_H_
+   *     #define FT_ERROR_START_LIST     switch ( error_code ) {
+   *     #define FT_ERRORDEF( e, v, s )    case v: return s;
+   *     #define FT_ERROR_END_LIST       }
+   *   ```
+   *
+   *   If you use `FT_CONFIG_OPTION_USE_MODULE_ERRORS`, `error_code` should
+   *   be replaced with `FT_ERROR_BASE(error_code)` in the last example.

-   *   LCD Filtering
+   *   Subpixel Rendering
    *
    * @abstract:
-   *   Reduce color fringes of subpixel-rendered bitmaps.
+   *   API to control subpixel rendering.
    *
    * @description:
-   *   Should you #define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in your
-   *   `ftoption.h', which enables patented ClearType-style rendering,
-   *   the LCD-optimized glyph bitmaps should be filtered to reduce color
-   *   fringes inherent to this technology.  The default FreeType LCD
-   *   rendering uses different technology, and API described below,
-   *   although available, does nothing.
+   *   FreeType provides two alternative subpixel rendering technologies. 
+   *   Should you define `FT_CONFIG_OPTION_SUBPIXEL_RENDERING` in your
+   *   `ftoption.h` file, this enables patented ClearType-style rendering. 
+   *   Otherwise, Harmony LCD rendering is enabled.  These technologies are
+   *   controlled differently and API described below, although always
+   *   available, performs its function when appropriate method is enabled
+   *   and does nothing otherwise.
    *
    *   ClearType-style LCD rendering exploits the color-striped structure of
    *   LCD pixels, increasing the available resolution in the direction of
-   *   the stripe (usually horizontal RGB) by a factor of~3.  Since these
-   *   subpixels are color pixels, using them unfiltered creates severe
-   *   color fringes.  Use the @FT_Library_SetLcdFilter API to specify a
-   *   low-pass filter, which is then applied to subpixel-rendered bitmaps
-   *   generated through @FT_Render_Glyph.  The filter sacrifices some of
-   *   the higher resolution to reduce color fringes, making the glyph image
-   *   slightly blurrier.  Positional improvements will remain.
-   *
-   *   A filter should have two properties:
-   *
-   *   1) It should be normalized, meaning the sum of the 5~components
-   *      should be 256 (0x100).  It is possible to go above or under this
-   *      target sum, however: going under means tossing out contrast, going
-   *      over means invoking clamping and thereby non-linearities that
-   *      increase contrast somewhat at the expense of greater distortion
-   *      and color-fringing.  Contrast is better enhanced through stem
-   *      darkening.
-   *
-   *   2) It should be color-balanced, meaning a filter `{~a, b, c, b, a~}'
-   *      where a~+ b~=~c.  It distributes the computed coverage for one
-   *      subpixel to all subpixels equally, sacrificing some won resolution
-   *      but drastically reducing color-fringing.  Positioning improvements
-   *      remain!  Note that color-fringing can only really be minimized
-   *      when using a color-balanced filter and alpha-blending the glyph
-   *      onto a surface in linear space; see @FT_Render_Glyph.
-   *
-   *   Regarding the form, a filter can be a `boxy' filter or a `beveled'
-   *   filter.  Boxy filters are sharper but are less forgiving of non-ideal
-   *   gamma curves of a screen (viewing angles!), beveled filters are
-   *   fuzzier but more tolerant.
-   *
-   *   Examples:
-   *
-   *   - [0x10 0x40 0x70 0x40 0x10] is beveled and neither balanced nor
-   *     normalized.
-   *
-   *   - [0x1A 0x33 0x4D 0x33 0x1A] is beveled and balanced but not
-   *     normalized.
-   *
-   *   - [0x19 0x33 0x66 0x4c 0x19] is beveled and normalized but not
-   *     balanced.
-   *
-   *   - [0x00 0x4c 0x66 0x4c 0x00] is boxily beveled and normalized but not
-   *     balanced.
-   *
-   *   - [0x00 0x55 0x56 0x55 0x00] is boxy, normalized, and almost
-   *     balanced.
-   *
-   *   - [0x08 0x4D 0x56 0x4D 0x08] is beveled, normalized and, almost
-   *     balanced.
-   *
-   *   The filter affects glyph bitmaps rendered through @FT_Render_Glyph,
-   *   @FT_Load_Glyph, and @FT_Load_Char.  It does _not_ affect the output
-   *   of @FT_Outline_Render and @FT_Outline_Get_Bitmap.
-   *
-   *   If this feature is activated, the dimensions of LCD glyph bitmaps are
-   *   either wider or taller than the dimensions of the corresponding
-   *   outline with regard to the pixel grid.  For example, for
-   *   @FT_RENDER_MODE_LCD, the filter adds 3~subpixels to the left, and
-   *   3~subpixels to the right.  The bitmap offset values are adjusted
-   *   accordingly, so clients shouldn't need to modify their layout and
-   *   glyph positioning code when enabling the filter.
-   *
-   *   It is important to understand that linear alpha blending and gamma
-   *   correction is critical for correctly rendering glyphs onto surfaces
-   *   without artifacts and even more critical when subpixel rendering is
-   *   involved.
-   *
-   *   Each of the 3~alpha values (subpixels) is independently used to blend
-   *   one color channel.  That is, red alpha blends the red channel of the
-   *   text color with the red channel of the background pixel.  The
-   *   distribution of density values by the color-balanced filter assumes
-   *   alpha blending is done in linear space; only then color artifacts
-   *   cancel out.
+   *   the stripe (usually horizontal RGB) by a factor of~3.  Using the
+   *   subpixels coverages unfiltered can create severe color fringes
+   *   especially when rendering thin features.  Indeed, to produce
+   *   black-on-white text, the nearby color subpixels must be dimmed
+   *   equally.
+   *
+   *   A good 5-tap FIR filter should be applied to subpixel coverages
+   *   regardless of pixel boundaries and should have these properties:
+   *
+   *   1. It should be symmetrical, like {~a, b, c, b, a~}, to avoid
+   *      any shifts in appearance.
+   *
+   *   2. It should be color-balanced, meaning a~+ b~=~c, to reduce color
+   *      fringes by distributing the computed coverage for one subpixel to
+   *      all subpixels equally.
+   *
+   *   3. It should be normalized, meaning 2a~+ 2b~+ c~=~1.0 to maintain
+   *      overall brightness.
+   *
+   *   Boxy 3-tap filter {0, 1/3, 1/3, 1/3, 0} is sharper but is less
+   *   forgiving of non-ideal gamma curves of a screen (and viewing angles),
+   *   beveled filters are fuzzier but more tolerant.
+   *
+   *   Use the @FT_Library_SetLcdFilter or @FT_Library_SetLcdFilterWeights
+   *   API to specify a low-pass filter, which is then applied to
+   *   subpixel-rendered bitmaps generated through @FT_Render_Glyph.
+   *
+   *   Harmony LCD rendering is suitable to panels with any regular subpixel
+   *   structure, not just monitors with 3 color striped subpixels, as long
+   *   as the color subpixels have fixed positions relative to the pixel
+   *   center.  In this case, each color channel is then rendered separately
+   *   after shifting the outline opposite to the subpixel shift so that the
+   *   coverage maps are aligned.  This method is immune to color fringes
+   *   because the shifts do not change integral coverage.
+   *
+   *   The subpixel geometry must be specified by xy-coordinates for each
+   *   subpixel. By convention they may come in the RGB order: {{-1/3, 0},
+   *   {0, 0}, {1/3, 0}} for standard RGB striped panel or {{-1/6, 1/4},
+   *   {-1/6, -1/4}, {1/3, 0}} for a certain PenTile panel.
+   *
+   *   Use the @FT_Library_SetLcdGeometry API to specify subpixel positions.
+   *   If one follows the RGB order convention, the same order applies to the
+   *   resulting @FT_PIXEL_MODE_LCD and @FT_PIXEL_MODE_LCD_V bitmaps.  Note,
+   *   however, that the coordinate frame for the latter must be rotated
+   *   clockwise.  Harmony with default LCD geometry is equivalent to
+   *   ClearType with light filter.
+   *
+   *   As a result of ClearType filtering or Harmony rendering, the
+   *   dimensions of LCD bitmaps can be either wider or taller than the
+   *   dimensions of the corresponding outline with regard to the pixel grid.
+   *   For example, for @FT_RENDER_MODE_LCD, the filter adds 2~subpixels to
+   *   the left, and 2~subpixels to the right.  The bitmap offset values are
+   *   adjusted accordingly, so clients shouldn't need to modify their layout
+   *   and glyph positioning code when enabling the filter.
+   *
+   *   The ClearType and Harmony rendering is applicable to glyph bitmaps
+   *   rendered through @FT_Render_Glyph, @FT_Load_Glyph, @FT_Load_Char, and
+   *   @FT_Glyph_To_Bitmap, when @FT_RENDER_MODE_LCD or @FT_RENDER_MODE_LCD_V
+   *   is specified.  This API does not control @FT_Outline_Render and
+   *   @FT_Outline_Get_Bitmap.
+   *
+   *   The described algorithms can completely remove color artefacts when
+   *   combined with gamma-corrected alpha blending in linear space.  Each of
+   *   the 3~alpha values (subpixels) must by independently used to blend one
+   *   color channel.  That is, red alpha blends the red channel of the text
+   *   color with the red channel of the background pixel.

-  * @description:
-  *   Open a new stream to parse LZW-compressed font files.  This is
-  *   mainly used to support the compressed `*.pcf.Z' fonts that come
-  *   with XFree86.
-  *
-  * @input:
-  *   stream :: The target embedding stream.
-  *
-  *   source :: The source stream.
-  *
-  * @return:
-  *   FreeType error code.  0~means success.
-  *
-  * @note:
-  *   The source stream must be opened _before_ calling this function.
-  *
-  *   Calling the internal function `FT_Stream_Close' on the new stream will
-  *   *not* call `FT_Stream_Close' on the source stream.  None of the stream
-  *   objects will be released to the heap.
-  *
-  *   The stream implementation is very basic and resets the decompression
-  *   process each time seeking backwards is needed within the stream
-  *
-  *   In certain builds of the library, LZW compression recognition is
-  *   automatically handled when calling @FT_New_Face or @FT_Open_Face.
-  *   This means that if no font driver is capable of handling the raw

+   * @description:
+   *   Open a new stream to parse LZW-compressed font files.  This is mainly
+   *   used to support the compressed `*.pcf.Z` fonts that come with XFree86.
+   *
+   * @input:
+   *   stream ::
+   *     The target embedding stream.
+   *
+   *   source ::
+   *     The source stream.
+   *
+   * @return:
+   *   FreeType error code.  0~means success.
+   *
+   * @note:
+   *   The source stream must be opened _before_ calling this function.
+   *
+   *   Calling the internal function `FT_Stream_Close` on the new stream will
+   *   **not** call `FT_Stream_Close` on the source stream.  None of the
+   *   stream objects will be released to the heap.
+   *
+   *   The stream implementation is very basic and resets the decompression
+   *   process each time seeking backwards is needed within the stream
+   *
+   *   In certain builds of the library, LZW compression recognition is
+   *   automatically handled when calling @FT_New_Face or @FT_Open_Face.
+   *   This means that if no font driver is capable of handling the raw
+   *   compressed file, the library will try to open a LZW stream from it and
+   *   re-open the face with it.
+   *
+   *   This function may return `FT_Err_Unimplemented_Feature` if your build
+   *   of FreeType was not compiled with LZW support.

+   *
+   * This file is used to define the FreeType module error codes.
+   *
+   * If the macro `FT_CONFIG_OPTION_USE_MODULE_ERRORS` in `ftoption.h` is
+   * set, the lower byte of an error value identifies the error code as
+   * usual.  In addition, the higher byte identifies the module.  For
+   * example, the error `FT_Err_Invalid_File_Format` has value 0x0003, the
+   * error `TT_Err_Invalid_File_Format` has value 0x1303, the error
+   * `T1_Err_Invalid_File_Format` has value 0x1403, etc.
+   *
+   * Note that `FT_Err_Ok`, `TT_Err_Ok`, etc. are always equal to zero,
+   * including the high byte.
+   *
+   * If `FT_CONFIG_OPTION_USE_MODULE_ERRORS` isn't set, the higher byte of an
+   * error value is set to zero.
+   *
+   * To hide the various `XXX_Err_` prefixes in the source code, FreeType
+   * provides some macros in `fttypes.h`.
+   *
+   *   FT_ERR( err )
+   *
+   *     Add current error module prefix (as defined with the `FT_ERR_PREFIX`
+   *     macro) to `err`.  For example, in the BDF module the line
+   *
+   *     ```
+   *       error = FT_ERR( Invalid_Outline );
+   *     ```
+   *
+   *     expands to
+   *
+   *     ```
+   *       error = BDF_Err_Invalid_Outline;
+   *     ```
+   *
+   *     For simplicity, you can always use `FT_Err_Ok` directly instead of
+   *     `FT_ERR( Ok )`.
+   *
+   *   FT_ERR_EQ( errcode, err )
+   *   FT_ERR_NEQ( errcode, err )
+   *
+   *     Compare error code `errcode` with the error `err` for equality and
+   *     inequality, respectively.  Example:
+   *
+   *     ```
+   *       if ( FT_ERR_EQ( error, Invalid_Outline ) )
+   *         ...
+   *     ```
+   *
+   *     Using this macro you don't have to think about error prefixes.  Of
+   *     course, if module errors are not active, the above example is the
+   *     same as
+   *
+   *     ```
+   *       if ( error == FT_Err_Invalid_Outline )
+   *         ...
+   *     ```
+   *
+   *   FT_ERROR_BASE( errcode )
+   *   FT_ERROR_MODULE( errcode )
+   *
+   *     Get base error and module error code, respectively.
+   *
+   * It can also be used to create a module error message table easily with
+   * something like
+   *
+   * ```
+   *   #undef FTMODERR_H_
+   *   #define FT_MODERRDEF( e, v, s )  { FT_Mod_Err_ ## e, s },
+   *   #define FT_MODERR_START_LIST     {
+   *   #define FT_MODERR_END_LIST       { 0, 0 } };
+   *
+   *   const struct
+   *   {
+   *     int          mod_err_offset;
+   *     const char*  mod_err_msg
+   *   } ft_mod_errors[] =
+   *
+   *   #include FT_MODULE_ERRORS_H
+   * ```

-   * @title:
-   *   The TrueType driver
-   *
-   * @abstract:
-   *   Controlling the TrueType driver module.
-   *
-   * @description:
-   *   While FreeType's TrueType driver doesn't expose API functions by
-   *   itself, it is possible to control its behaviour with @FT_Property_Set
-   *   and @FT_Property_Get.  The following lists the available properties
-   *   together with the necessary macros and structures.
-   *
-   *   The TrueType driver's module name is `truetype'.
-   *
-   *   We start with a list of definitions, kindly provided by Greg
-   *   Hitchcock.
-   *
-   *   _Bi-Level_ _Rendering_
-   *
-   *   Monochromatic rendering, exclusively used in the early days of
-   *   TrueType by both Apple and Microsoft.  Microsoft's GDI interface
-   *   supported hinting of the right-side bearing point, such that the
-   *   advance width could be non-linear.  Most often this was done to
-   *   achieve some level of glyph symmetry.  To enable reasonable
-   *   performance (e.g., not having to run hinting on all glyphs just to
-   *   get the widths) there was a bit in the head table indicating if the
-   *   side bearing was hinted, and additional tables, `hdmx' and `LTSH', to
-   *   cache hinting widths across multiple sizes and device aspect ratios.
-   *
-   *   _Font_ _Smoothing_
-   *
-   *   Microsoft's GDI implementation of anti-aliasing.  Not traditional
-   *   anti-aliasing as the outlines were hinted before the sampling.  The
-   *   widths matched the bi-level rendering.
-   *
-   *   _ClearType_ _Rendering_
-   *
-   *   Technique that uses physical subpixels to improve rendering on LCD
-   *   (and other) displays.  Because of the higher resolution, many methods
-   *   of improving symmetry in glyphs through hinting the right-side
-   *   bearing were no longer necessary.  This lead to what GDI calls
-   *   `natural widths' ClearType, see
-   *   http://www.beatstamm.com/typography/RTRCh4.htm#Sec21.  Since hinting
-   *   has extra resolution, most non-linearity went away, but it is still
-   *   possible for hints to change the advance widths in this mode.
-   *
-   *   _ClearType_ _Compatible_ _Widths_
-   *
-   *   One of the earliest challenges with ClearType was allowing the
-   *   implementation in GDI to be selected without requiring all UI and
-   *   documents to reflow.  To address this, a compatible method of
-   *   rendering ClearType was added where the font hints are executed once
-   *   to determine the width in bi-level rendering, and then re-run in
-   *   ClearType, with the difference in widths being absorbed in the font
-   *   hints for ClearType (mostly in the white space of hints); see
-   *   http://www.beatstamm.com/typography/RTRCh4.htm#Sec20.  Somewhat by
-   *   definition, compatible width ClearType allows for non-linear widths,
-   *   but only when the bi-level version has non-linear widths.
-   *
-   *   _ClearType_ _Subpixel_ _Positioning_
-   *
-   *   One of the nice benefits of ClearType is the ability to more crisply
-   *   display fractional widths; unfortunately, the GDI model of integer
-   *   bitmaps did not support this.  However, the WPF and Direct Write
-   *   frameworks do support fractional widths.  DWrite calls this `natural
-   *   mode', not to be confused with GDI's `natural widths'.  Subpixel
-   *   positioning, in the current implementation of Direct Write,
-   *   unfortunately does not support hinted advance widths, see
-   *   http://www.beatstamm.com/typography/RTRCh4.htm#Sec22.  Note that the
-   *   TrueType interpreter fully allows the advance width to be adjusted in
-   *   this mode, just the DWrite client will ignore those changes.
-   *
-   *   _ClearType_ _Backward_ _Compatibility_
-   *
-   *   This is a set of exceptions made in the TrueType interpreter to
-   *   minimize hinting techniques that were problematic with the extra
-   *   resolution of ClearType; see
-   *   http://www.beatstamm.com/typography/RTRCh4.htm#Sec1 and
-   *   http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx.
-   *   This technique is not to be confused with ClearType compatible
-   *   widths.  ClearType backward compatibility has no direct impact on
-   *   changing advance widths, but there might be an indirect impact on
-   *   disabling some deltas.  This could be worked around in backward
-   *   compatibility mode.
-   *
-   *   _Native_ _ClearType_ _Mode_
-   *
-   *   (Not to be confused with `natural widths'.)  This mode removes all
-   *   the exceptions in the TrueType interpreter when running with
-   *   ClearType.  Any issues on widths would still apply, though.

-   * @property:
-   *   interpreter-version
-   *
-   * @description:
-   *   Currently, three versions are available, two representing the
-   *   bytecode interpreter with subpixel hinting support (old `Infinality'
-   *   code and new stripped-down and higher performance `minimal' code) and
-   *   one without, respectively.  The default is subpixel support if
-   *   TT_CONFIG_OPTION_SUBPIXEL_HINTING is defined, and no subpixel support
-   *   otherwise (since it isn't available then).
-   *
-   *   If subpixel hinting is on, many TrueType bytecode instructions behave
-   *   differently compared to B/W or grayscale rendering (except if `native
-   *   ClearType' is selected by the font).  Microsoft's main idea is to
-   *   render at a much increased horizontal resolution, then sampling down
-   *   the created output to subpixel precision.  However, many older fonts
-   *   are not suited to this and must be specially taken care of by
-   *   applying (hardcoded) tweaks in Microsoft's interpreter.
-   *
-   *   Details on subpixel hinting and some of the necessary tweaks can be
-   *   found in Greg Hitchcock's whitepaper at
-   *   `http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx'. 
-   *   Note that FreeType currently doesn't really `subpixel hint' (6x1, 6x2,
-   *   or 6x5 supersampling) like discussed in the paper.  Depending on the
-   *   chosen interpreter, it simply ignores instructions on vertical stems
-   *   to arrive at very similar results.
-   *
-   *   The following example code demonstrates how to deactivate subpixel
-   *   hinting (omitting the error handling).
-   *
-   *   {
-   *     FT_Library  library;
-   *     FT_Face     face;
-   *     FT_UInt     interpreter_version = TT_INTERPRETER_VERSION_35;
-   *
-   *
-   *     FT_Init_FreeType( &library );
-   *
-   *     FT_Property_Set( library, "truetype",
-   *                               "interpreter-version",
-   *                               &interpreter_version );
-   *   }
-   *
-   * @note:
-   *   This property can be used with @FT_Property_Get also.
-   *
-   *   This property can be set via the `FREETYPE_PROPERTIES' environment
-   *   variable (using values `35', `38', or `40').

-   *
-   * @description:
-   *   A list of constants used for the @interpreter-version property to
-   *   select the hinting engine for Truetype fonts.
-   *
-   *   The numeric value in the constant names represents the version
-   *   number as returned by the `GETINFO' bytecode instruction.
-   *
-   * @values:
-   *   TT_INTERPRETER_VERSION_35 ::
-   *     Version~35 corresponds to MS rasterizer v.1.7 as used e.g. in
-   *     Windows~98; only grayscale and B/W rasterizing is supported.
-   *
-   *   TT_INTERPRETER_VERSION_38 ::
-   *     Version~38 corresponds to MS rasterizer v.1.9; it is roughly
-   *     equivalent to the hinting provided by DirectWrite ClearType (as can
-   *     be found, for example, in the Internet Explorer~9 running on
-   *     Windows~7).  It is used in FreeType to select the `Infinality'
-   *     subpixel hinting code.  The code may be removed in a future
-   *     version.
-   *
-   *   TT_INTERPRETER_VERSION_40 ::
-   *     Version~40 corresponds to MS rasterizer v.2.1; it is roughly
-   *     equivalent to the hinting provided by DirectWrite ClearType (as can
-   *     be found, for example, in Microsoft's Edge Browser on Windows~10). 
-   *     It is used in FreeType to select the `minimal' subpixel hinting
-   *     code, a stripped-down and higher performance version of the
-   *     `Infinality' code.
-   *
-   * @note:
-   *   This property controls the behaviour of the bytecode interpreter
-   *   and thus how outlines get hinted.  It does *not* control how glyph
-   *   get rasterized!  In particular, it does not control subpixel color
-   *   filtering.
-   *
-   *   If FreeType has not been compiled with the configuration option
-   *   TT_CONFIG_OPTION_SUBPIXEL_HINTING, selecting version~38 or~40 causes
-   *   an `FT_Err_Unimplemented_Feature' error.
-   *
-   *   Depending on the graphics framework, Microsoft uses different
-   *   bytecode and rendering engines.  As a consequence, the version
-   *   numbers returned by a call to the `GETINFO' bytecode instruction are
-   *   more convoluted than desired.
-   *
-   *   Here are two tables that try to shed some light on the possible
-   *   values for the MS rasterizer engine, together with the additional
-   *   features introduced by it.

-   *
-   *   Color and Gray ClearType are the two available variants of
-   *   `Y-direction ClearType', meaning grayscale rasterization along the
-   *   Y-direction; the name used in the TrueType specification for this
-   *   feature is `symmetric smoothing'.  `Classic ClearType' is the
-   *   original algorithm used before introducing a modified version in
-   *   Win~XP.  Another name for v1.6's grayscale rendering is `font
-   *   smoothing', and `Color ClearType' is sometimes also called `DWrite
-   *   ClearType'.  To differentiate between today's Color ClearType and the
-   *   earlier ClearType variant with B/W rendering along the vertical axis,
-   *   the latter is sometimes called `GDI ClearType'.
-   *
-   *   `Normal' and `high' sampling describe the (virtual) resolution to
-   *   access the rasterized outline after the hinting process.  `Normal'
-   *   means 1 sample per grid line (i.e., B/W).  In the current Microsoft
-   *   implementation, `high' means an extra virtual resolution of 16x16 (or
-   *   16x1) grid lines per pixel for bytecode instructions like `MIRP'.
-   *   After hinting, these 16 grid lines are mapped to 6x5 (or 6x1) grid
-   *   lines for color filtering if Color ClearType is activated.
-   *
-   *   Note that `Gray ClearType' is essentially the same as v1.6's
-   *   grayscale rendering.  However, the GETINFO instruction handles it
-   *   differently: v1.6 returns bit~12 (hinting for grayscale), while v2.1
-   *   returns bits~13 (hinting for ClearType), 18 (symmetrical smoothing),
-   *   and~19 (Gray ClearType).  Also, this mode respects bits 2 and~3 for
-   *   the version~1 gasp table exclusively (like Color ClearType), while
-   *   v1.6 only respects the values of version~0 (bits 0 and~1).
-   *
-   *   Keep in mind that the features of the above interpreter versions
-   *   might not map exactly to FreeType features or behavior because it is
-   *   a fundamentally different library with different internals.

+   *     glyph image.
+   *
+   *   request_size ::
+   *     A handle to a function used to request the new character size.  Can
+   *     be set to 0 if the scaling done in the base layer suffices.
+   *
+   *   select_size ::
+   *     A handle to a function used to select a new fixed size.  It is used
+   *     only if @FT_FACE_FLAG_FIXED_SIZES is set.  Can be set to 0 if the
+   *     scaling done in the base layer suffices.
+   * @note:
+   *   Most function pointers, with the exception of `load_glyph`, can be set
+   *   to 0 to indicate a default behaviour.

+   *   which is not covered by the generic @FT_CharMap structure.  This
+   *   structure can be accessed with the @FT_Get_TT_CMap_Info function.
+   *
+   * @fields:
+   *   language ::
+   *     The language ID used in Mac fonts.  Definitions of values are in
+   *     `ttnameid.h`.
+   *
+   *   format ::
+   *     The cmap format.  OpenType 1.6 defines the formats 0 (byte encoding
+   *     table), 2~(high-byte mapping through table), 4~(segment mapping to
+   *     delta values), 6~(trimmed table mapping), 8~(mixed 16-bit and 32-bit
+   *     coverage), 10~(trimmed array), 12~(segmented coverage), 13~(last
+   *     resort font), and 14 (Unicode Variation Sequences).
