Date: Sun, 3 Jun 2018 16:03:06 -0400 (EDT)

branch: master
commit f999375a9a834666f82928f9ad6293d9b25213a5
Author: Werner Lemberg <address@hidden>
Commit: Werner Lemberg <address@hidden>

    [GSoC] include/*.*, devel/*.*: Convert block comments to `light' style.
    
    This second and final monster commit was created by applying Nikhil's
    scripts `docconverter.py' and `markify.py' to all C header and source files,
    followed up by minor manual clean-up.
    
    No change in functionality, of course.
    
    I used commit f7419907bc6044b9b7057f9789866426c804ba82 from
    https://github.com/nikramakrishnan/freetype-docs.git.

+   *
+   * Define TT_CONFIG_OPTION_SUBPIXEL_HINTING if you want to compile
+   * subpixel hinting support into the TrueType driver.  This modifies the
+   * TrueType hinting mechanism when anything but FT_RENDER_MODE_MONO is
+   * requested.
+   *
+   * 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.

+   * 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>.

+   *
+   * @Enum:
+   *   FT_Encoding
+   *
+   * @Description:
+   *   An enumeration to specify character sets supported by charmaps.
+   *   Used in the @FT_Select_Charmap API function.
+   *
+   * @Note:
+   *   Despite the name, this enumeration lists specific character
+   *   repertories (i.e., charsets), and not text encoding methods (e.g.,
+   *   UTF-8, UTF-16, etc.).
+   *
+   *   Other encodings might be defined in the future.
+   *
+   * @Values:
+   *   FT_ENCODING_NONE ::
+   *     The encoding value~0 is reserved.
+   *
+   *   FT_ENCODING_UNICODE ::
+   *     The Unicode character set.  This value covers all versions of
+   *     the Unicode repertoire, including ASCII and Latin-1.  Most fonts
+   *     include a Unicode charmap, but not all of them.
+   *
+   *     For example, if you want to access Unicode value U+1F028 (and
+   *     the font contains it), use value 0x1F028 as the input value for
+   *     @FT_Get_Char_Index.
+   *
+   *   FT_ENCODING_MS_SYMBOL ::
+   *     Microsoft Symbol encoding, used to encode mathematical symbols
+   *     and wingdings.  For more information, see
+   *     `https://www.microsoft.com/typography/otspec/recom.htm',
+   *     `http://www.kostis.net/charsets/symbol.htm', and
+   *     `http://www.kostis.net/charsets/wingding.htm'.
+   *
+   *     This encoding uses character codes from the PUA (Private Unicode
+   *     Area) in the range U+F020-U+F0FF.
+   *
+   *   FT_ENCODING_SJIS ::
+   *     Shift JIS encoding for Japanese.  More info at
+   *     `https://en.wikipedia.org/wiki/Shift_JIS'.  See note on
+   *     multi-byte encodings below.
+   *
+   *   FT_ENCODING_PRC ::
+   *     Corresponds to encoding systems mainly for Simplified Chinese as
+   *     used in People's Republic of China (PRC).  The encoding layout
+   *     is based on GB~2312 and its supersets GBK and GB~18030.
+   *
+   *   FT_ENCODING_BIG5 ::
+   *     Corresponds to an encoding system for Traditional Chinese as
+   *     used in Taiwan and Hong Kong.
+   *
+   *   FT_ENCODING_WANSUNG ::
+   *     Corresponds to the Korean encoding system known as Extended
+   *     Wansung (MS Windows code page 949).
+   *     For more information see
+   *     
`https://www.unicode.org/Public/MAPPINGS/VENDORS/MICSFT/WindowsBestFit/bestfit949.txt'.
+   *
+   *   FT_ENCODING_JOHAB ::
+   *     The Korean standard character set (KS~C 5601-1992), which
+   *     corresponds to MS Windows code page 1361.  This character set
+   *     includes all possible Hangul character combinations.
+   *
+   *   FT_ENCODING_ADOBE_LATIN_1 ::
+   *     Corresponds to a Latin-1 encoding as defined in a Type~1
+   *     PostScript font.  It is limited to 256 character codes.
+   *
+   *   FT_ENCODING_ADOBE_STANDARD ::
+   *     Adobe Standard encoding, as found in Type~1, CFF, and
+   *     OpenType/CFF fonts.  It is limited to 256 character codes.
+   *
+   *   FT_ENCODING_ADOBE_EXPERT ::
+   *     Adobe Expert encoding, as found in Type~1, CFF, and OpenType/CFF
+   *     fonts.  It is limited to 256 character codes.
+   *
+   *   FT_ENCODING_ADOBE_CUSTOM ::
+   *     Corresponds to a custom encoding, as found in Type~1, CFF, and
+   *     OpenType/CFF fonts.  It is limited to 256 character codes.
+   *
+   *   FT_ENCODING_APPLE_ROMAN ::
+   *     Apple roman encoding.  Many TrueType and OpenType fonts contain
+   *     a charmap for this 8-bit encoding, since older versions of Mac
+   *     OS are able to use it.
+   *
+   *   FT_ENCODING_OLD_LATIN_2 ::
+   *     This value is deprecated and was neither used nor reported by
+   *     FreeType.  Don't use or test for it.
+   *
+   *   FT_ENCODING_MS_SJIS ::
+   *     Same as FT_ENCODING_SJIS.  Deprecated.
+   *
+   *   FT_ENCODING_MS_GB2312 ::
+   *     Same as FT_ENCODING_PRC.  Deprecated.

+   *
+   *   FT_ENCODING_MS_JOHAB ::
+   *     Same as FT_ENCODING_JOHAB.  Deprecated.
+   *
+   * @Note:
+   *   By default, FreeType enables a Unicode charmap and tags it with
+   *   FT_ENCODING_UNICODE when it is either provided or can be generated
+   *   from PostScript glyph name dictionaries in the font file.
+   *   All other encodings are considered legacy and tagged only if
+   *   explicitly defined in the font file.  Otherwise, FT_ENCODING_NONE
+   *   is used.
+   *
+   *   FT_ENCODING_NONE is set by the BDF and PCF drivers if the charmap
+   *   is neither Unicode nor ISO-8859-1 (otherwise it is set to
+   *   FT_ENCODING_UNICODE).  Use @FT_Get_BDF_Charset_ID to find out
+   *   which encoding is really present.  If, for example, the
+   *   `cs_registry' field is `KOI8' and the `cs_encoding' field is `R',
+   *   the font is encoded in KOI8-R.
+   *
+   *   FT_ENCODING_NONE is always set (with a single exception) by the
+   *   winfonts driver.  Use @FT_Get_WinFNT_Header and examine the
+   *   `charset' field of the @FT_WinFNT_HeaderRec structure to find out
+   *   which encoding is really present.  For example,
+   *   @FT_WinFNT_ID_CP1251 (204) means Windows code page 1251 (for
+   *   Russian).
+   *
+   *   FT_ENCODING_NONE is set if `platform_id' is @TT_PLATFORM_MACINTOSH
+   *   and `encoding_id' is not `TT_MAC_ID_ROMAN' (otherwise it is set to
+   *   FT_ENCODING_APPLE_ROMAN).
+   *
+   *   If `platform_id' is @TT_PLATFORM_MACINTOSH, use the function

+   * @Struct:
+   *   FT_FaceRec
+   *
+   * @Description:
+   *   FreeType root face class structure.  A face object models a
+   *   typeface in a font file.
+   *
+   * @Fields:
+   *   num_faces ::
+   *     The number of faces in the font file.  Some
+   *     font formats can have multiple faces in
+   *     a single font file.
+   *
+   *   face_index ::
+   *     This field holds two different values.
+   *     Bits 0-15 are the index of the face in the
+   *     font file (starting with value~0).  They
+   *     are set to~0 if there is only one face in
+   *     the font file.
+   *
+   *     [Since 2.6.1] Bits 16-30 are relevant to GX
+   *     and OpenType variation fonts only, holding
+   *     the named instance index for the current
+   *     face index (starting with value~1; value~0
+   *     indicates font access without a named
+   *     instance).  For non-variation fonts, bits
+   *     16-30 are ignored.  If we have the third
+   *     named instance of face~4, say, `face_index'
+   *     is set to 0x00030004.
+   *
+   *     Bit 31 is always zero (this is,
+   *     `face_index' is always a positive value).
+   *
+   *     [Since 2.9] Changing the design coordinates
+   *     with @FT_Set_Var_Design_Coordinates or
+   *     @FT_Set_Var_Blend_Coordinates does not
+   *     influence the named instance index value
+   *     (only @FT_Set_Named_Instance does that).
+   *
+   *   face_flags ::
+   *     A set of bit flags that give important
+   *     information about the face; see
+   *     @FT_FACE_FLAG_XXX for the details.
+   *
+   *   style_flags ::
+   *     The lower 16~bits contain a set of bit
+   *     flags indicating the style of the face; see
+   *     @FT_STYLE_FLAG_XXX for the details.
+   *
+   *     [Since 2.6.1] Bits 16-30 hold the number
+   *     of named instances available for the
+   *     current face if we have a GX or OpenType
+   *     variation (sub)font.  Bit 31 is always zero
+   *     (this is, `style_flags' is always a
+   *     positive value).  Note that a variation
+   *     font has always at least one named
+   *     instance, namely the default instance.
+   *
+   *   num_glyphs ::
+   *     The number of glyphs in the face.  If the
+   *     face is scalable and has sbits (see
+   *     `num_fixed_sizes'), it is set to the number
+   *     of outline glyphs.
+   *
+   *     For CID-keyed fonts (not in an SFNT
+   *     wrapper) this value gives the highest CID
+   *     used in the font.
+   *
+   *   family_name ::
+   *     The face's family name.  This is an ASCII
+   *     string, usually in English, that describes
+   *     the typeface's family (like `Times New
+   *     Roman', `Bodoni', `Garamond', etc).  This
+   *     is a least common denominator used to list
+   *     fonts.  Some formats (TrueType & OpenType)
+   *     provide localized and Unicode versions of
+   *     this string.  Applications should use the
+   *     format specific interface to access them.
+   *     Can be NULL (e.g., in fonts embedded in a
+   *     PDF file).
+   *
+   *     In case the font doesn't provide a specific
+   *     family name entry, FreeType tries to
+   *     synthesize one, deriving it from other name
+   *     entries.
+   *
+   *   style_name ::
+   *     The face's style name.  This is an ASCII
+   *     string, usually in English, that describes
+   *     the typeface's style (like `Italic',
+   *     `Bold', `Condensed', etc).  Not all font
+   *     formats provide a style name, so this field
+   *     is optional, and can be set to NULL.  As
+   *     for `family_name', some formats provide
+   *     localized and Unicode versions of this
+   *     string.  Applications should use the format
+   *     specific interface to access them.
+   *
+   *   num_fixed_sizes ::
+   *     The number of bitmap strikes in the face.
+   *     Even if the face is scalable, there might
+   *     still be bitmap strikes, which are called
+   *     `sbits' in that case.
+   *
+   *   available_sizes ::
+   *     An array of @FT_Bitmap_Size for all bitmap
+   *     strikes in the face.  It is set to NULL if
+   *     there is no bitmap strike.
+   *
+   *     Note that FreeType tries to sanitize the
+   *     strike data since they are sometimes sloppy
+   *     or incorrect, but this can easily fail.
+   *
+   *   num_charmaps ::
+   *     The number of charmaps in the face.
+   *
+   *   charmaps ::
+   *     An array of the charmaps of the face.
+   *
+   *   generic ::
+   *     A field reserved for client uses.  See the
+   *     @FT_Generic type description.
+   *
+   *   bbox ::
+   *     The font bounding box.  Coordinates are
+   *     expressed in font units (see
+   *     `units_per_EM').  The box is large enough
+   *     to contain any glyph from the font.  Thus,
+   *     `bbox.yMax' can be seen as the `maximum
+   *     ascender', and `bbox.yMin' as the `minimum
+   *     descender'.  Only relevant for scalable
+   *     formats.
+   *
+   *     Note that the bounding box might be off by
+   *     (at least) one pixel for hinted fonts.  See
+   *     @FT_Size_Metrics for further discussion.
+   *
+   *   units_per_EM ::
+   *     The number of font units per EM square for
+   *     this face.  This is typically 2048 for
+   *     TrueType fonts, and 1000 for Type~1 fonts.
+   *     Only relevant for scalable formats.
+   *
+   *   ascender ::
+   *     The typographic ascender of the face,
+   *     expressed in font units.  For font formats
+   *     not having this information, it is set to
+   *     `bbox.yMax'.  Only relevant for scalable
+   *     formats.
+   *
+   *   descender ::
+   *     The typographic descender of the face,
+   *     expressed in font units.  For font formats
+   *     not having this information, it is set to
+   *     `bbox.yMin'.  Note that this field is
+   *     negative for values below the baseline.
+   *     Only relevant for scalable formats.
+   *
+   *   height ::
+   *     This value is the vertical distance
+   *     between two consecutive baselines,
+   *     expressed in font units.  It is always
+   *     positive.  Only relevant for scalable
+   *     formats.
+   *
+   *     If you want the global glyph height, use
+   *     `ascender - descender'.
+   *
+   *   max_advance_width ::
+   *     The maximum advance width, in font units,
+   *     for all glyphs in this face.  This can be
+   *     used to make word wrapping computations
+   *     faster.  Only relevant for scalable
+   *     formats.
+   *
+   *   max_advance_height ::
+   *     The maximum advance height, in font units,
+   *     for all glyphs in this face.  This is only
+   *     relevant for vertical layouts, and is set
+   *     to `height' for fonts that do not provide
+   *     vertical metrics.  Only relevant for
+   *     scalable formats.
+   *
+   *   underline_position ::
+   *     The position, in font units, of the
+   *     underline line for this face.  It is the
+   *     center of the underlining stem.  Only
+   *     relevant for scalable formats.
+   *
+   *   underline_thickness ::
+   *     The thickness, in font units, of the
+   *     underline for this face.  Only relevant for
+   *     scalable formats.
+   *
+   *   glyph ::
+   *     The face's associated glyph slot(s).
+   *
+   *   size ::
+   *     The current active size for this face.
+   *
+   *   charmap ::
+   *     The current active charmap for this face.
+   *
+   * @Note:
+   *   Fields may be changed after a call to @FT_Attach_File or
+   *   @FT_Attach_Stream.
+   *
+   *   For an OpenType variation font, the values of the following fields
+   *   can change after a call to @FT_Set_Var_Design_Coordinates (and
+   *   friends) if the font contains an `MVAR' table: `ascender',
+   *   `descender', `height', `underline_position', and
+   *   `underline_thickness'.
+   *
+   *   Especially for TrueType fonts see also the documentation for
+   *   @FT_Size_Metrics.

+   *
+   * @Description:
+   *   A list of bit flags used in the `face_flags' field of the
+   *   @FT_FaceRec structure.  They inform client applications of
+   *   properties of the corresponding face.
+   *
+   * @Values:
+   *   FT_FACE_FLAG_SCALABLE ::
+   *     The face contains outline glyphs.  Note that a face can contain
+   *     bitmap strikes also, i.e., a face can have both this flag and
+   *     @FT_FACE_FLAG_FIXED_SIZES set.
+   *
+   *   FT_FACE_FLAG_FIXED_SIZES ::
+   *     The face contains bitmap strikes.  See also the
+   *     `num_fixed_sizes' and `available_sizes' fields of @FT_FaceRec.
+   *
+   *   FT_FACE_FLAG_FIXED_WIDTH ::
+   *     The face contains fixed-width characters (like Courier, Lucida,
+   *     MonoType, etc.).
+   *
+   *   FT_FACE_FLAG_SFNT ::
+   *     The face uses the SFNT storage scheme.  For now, this means
+   *     TrueType and OpenType.
+   *
+   *   FT_FACE_FLAG_HORIZONTAL ::
+   *     The face contains horizontal glyph metrics.  This should be set
+   *     for all common formats.
+   *
+   *   FT_FACE_FLAG_VERTICAL ::
+   *     The face contains vertical glyph metrics.  This is only
+   *     available in some formats, not all of them.
+   *
+   *   FT_FACE_FLAG_KERNING ::
+   *     The face contains kerning information.  If set, the kerning
+   *     distance can be retrieved using the function @FT_Get_Kerning.
+   *     Otherwise the function always return the vector (0,0).  Note
+   *     that FreeType doesn't handle kerning data from the SFNT `GPOS'

+   *
+   *   FT_FACE_FLAG_FAST_GLYPHS ::
+   *     THIS FLAG IS DEPRECATED.  DO NOT USE OR TEST IT.
+   *
+   *   FT_FACE_FLAG_MULTIPLE_MASTERS ::
+   *     The face contains multiple masters and is capable of
+   *     interpolating between them.  Supported formats are Adobe MM,
+   *     TrueType GX, and OpenType variation fonts.
+   *
+   *     See section @multiple_masters for API details.
+   *
+   *   FT_FACE_FLAG_GLYPH_NAMES ::
+   *     The face contains glyph names, which can be retrieved using
+   *     @FT_Get_Glyph_Name.  Note that some TrueType fonts contain
+   *     broken glyph name tables.  Use the function
+   *     @FT_Has_PS_Glyph_Names when needed.
+   *
+   *   FT_FACE_FLAG_EXTERNAL_STREAM ::
+   *     Used internally by FreeType to indicate that a face's stream was
+   *     provided by the client application and should not be destroyed
+   *     when @FT_Done_Face is called.  Don't read or test this flag.
+   *
+   *   FT_FACE_FLAG_HINTER ::
+   *     The font driver has a hinting machine of its own.  For example,
+   *     with TrueType fonts, it makes sense to use data from the SFNT
+   *     `gasp' table only if the native TrueType hinting engine (with

+   *     fonts this has the consequence that not all index values are a

+   *
+   * @Fields:
+   *   x_ppem ::
+   *     The width of the scaled EM square in pixels, hence
+   *     the term `ppem' (pixels per EM).  It is also
+   *     referred to as `nominal width'.
+   *
+   *   y_ppem ::
+   *     The height of the scaled EM square in pixels,
+   *     hence the term `ppem' (pixels per EM).  It is also
+   *     referred to as `nominal height'.
+   *
+   *   x_scale ::
+   *     A 16.16 fractional scaling value to convert
+   *     horizontal metrics from font units to 26.6
+   *     fractional pixels.  Only relevant for scalable
+   *     font formats.
+   *
+   *   y_scale ::
+   *     A 16.16 fractional scaling value to convert
+   *     vertical metrics from font units to 26.6
+   *     fractional pixels.  Only relevant for scalable
+   *     font formats.
+   *
+   *   ascender ::
+   *     The ascender in 26.6 fractional pixels, rounded up
+   *     to an integer value.  See @FT_FaceRec for the
+   *     details.
+   *
+   *   descender ::
+   *     The descender in 26.6 fractional pixels, rounded
+   *     down to an integer value.  See @FT_FaceRec for the
+   *     details.
+   *
+   *   height ::
+   *     The height in 26.6 fractional pixels, rounded to
+   *     an integer value.  See @FT_FaceRec for the
+   *     details.
+   *
+   *   max_advance ::
+   *     The maximum advance width in 26.6 fractional
+   *     pixels, rounded to an integer value.  See
+   *     @FT_FaceRec for the details.
+   *
+   * @Note:
+   *   The scaling values, if relevant, are determined first during a
+   *   size changing operation.  The remaining fields are then set by the
+   *   driver.  For scalable formats, they are usually set to scaled

+   *   }

+   *   Note that due to glyph hinting and the selected rendering mode
+   *   these values are usually not exact; consequently, they must be

+   *   Indeed, the only way to get the exact metrics is to render _all_
+   *   glyphs.  As this would be a definite performance hit, it is up to

+   * @Struct:
+   *   FT_GlyphSlotRec
+   *
+   * @Description:
+   *   FreeType root glyph slot class structure.  A glyph slot is a
+   *   container where individual glyphs can be loaded, be they in
+   *   outline or bitmap format.
+   *
+   * @Fields:
+   *   library ::
+   *     A handle to the FreeType library instance
+   *     this slot belongs to.
+   *
+   *   face ::
+   *     A handle to the parent face object.
+   *
+   *   next ::
+   *     In some cases (like some font tools), several
+   *     glyph slots per face object can be a good
+   *     thing.  As this is rare, the glyph slots are
+   *     listed through a direct, single-linked list
+   *     using its `next' field.
+   *
+   *   generic ::
+   *     A typeless pointer unused by the FreeType
+   *     library or any of its drivers.  It can be
+   *     used by client applications to link their own
+   *     data to each glyph slot object.
+   *
+   *   metrics ::
+   *     The metrics of the last loaded glyph in the
+   *     slot.  The returned values depend on the last
+   *     load flags (see the @FT_Load_Glyph API
+   *     function) and can be expressed either in 26.6
+   *     fractional pixels or font units.
+   *
+   *     Note that even when the glyph image is
+   *     transformed, the metrics are not.
+   *
+   *   linearHoriAdvance ::
+   *     The advance width of the unhinted glyph.
+   *     Its value is expressed in 16.16 fractional
+   *     pixels, unless @FT_LOAD_LINEAR_DESIGN is set
+   *     when loading the glyph.  This field can be
+   *     important to perform correct WYSIWYG layout.
+   *     Only relevant for outline glyphs.
+   *
+   *   linearVertAdvance ::
+   *     The advance height of the unhinted glyph.
+   *     Its value is expressed in 16.16 fractional
+   *     pixels, unless @FT_LOAD_LINEAR_DESIGN is set
+   *     when loading the glyph.  This field can be
+   *     important to perform correct WYSIWYG layout.
+   *     Only relevant for outline glyphs.
+   *
+   *   advance ::
+   *     This shorthand is, depending on
+   *     @FT_LOAD_IGNORE_TRANSFORM, the transformed
+   *     (hinted) advance width for the glyph, in 26.6
+   *     fractional pixel format.  As specified with
+   *     @FT_LOAD_VERTICAL_LAYOUT, it uses either the
+   *     `horiAdvance' or the `vertAdvance' value of
+   *     `metrics' field.
+   *
+   *   format ::
+   *     This field indicates the format of the image
+   *     contained in the glyph slot.  Typically
+   *     @FT_GLYPH_FORMAT_BITMAP,
+   *     @FT_GLYPH_FORMAT_OUTLINE, or
+   *     @FT_GLYPH_FORMAT_COMPOSITE, but other values
+   *     are possible.
+   *
+   *   bitmap ::
+   *     This field is used as a bitmap descriptor.
+   *     Note that the address and content of the
+   *     bitmap buffer can change between calls of
+   *     @FT_Load_Glyph and a few other functions.
+   *
+   *   bitmap_left ::
+   *     The bitmap's left bearing expressed in
+   *     integer pixels.
+   *
+   *   bitmap_top ::
+   *     The bitmap's top bearing expressed in integer
+   *     pixels.  This is the distance from the
+   *     baseline to the top-most glyph scanline,
+   *     upwards y~coordinates being *positive*.
+   *
+   *   outline ::
+   *     The outline descriptor for the current glyph
+   *     image if its format is
+   *     @FT_GLYPH_FORMAT_OUTLINE.  Once a glyph is
+   *     loaded, `outline' can be transformed,
+   *     distorted, emboldened, etc.  However, it must
+   *     not be freed.
+   *
+   *   num_subglyphs ::
+   *     The number of subglyphs in a composite glyph.
+   *     This field is only valid for the composite
+   *     glyph format that should normally only be
+   *     loaded with the @FT_LOAD_NO_RECURSE flag.
+   *
+   *   subglyphs ::
+   *     An array of subglyph descriptors for
+   *     composite glyphs.  There are `num_subglyphs'
+   *     elements in there.  Currently internal to
+   *     FreeType.
+   *
+   *   control_data ::
+   *     Certain font drivers can also return the
+   *     control data for a given glyph image (e.g.
+   *     TrueType bytecode, Type~1 charstrings, etc.).
+   *     This field is a pointer to such data; it is
+   *     currently internal to FreeType.
+   *
+   *   control_len ::
+   *     This is the length in bytes of the control
+   *     data.  Currently internal to FreeType.
+   *
+   *   other ::
+   *     Reserved.
+   *
+   *   lsb_delta ::
+   *     The difference between hinted and unhinted
+   *     left side bearing while auto-hinting is
+   *     active.  Zero otherwise.
+   *
+   *   rsb_delta ::
+   *     The difference between hinted and unhinted
+   *     right side bearing while auto-hinting is
+   *     active.  Zero otherwise.
+   *
+   * @Note:
+   *   If @FT_Load_Glyph is called with default flags (see
+   *   @FT_LOAD_DEFAULT) the glyph image is loaded in the glyph slot in
+   *   its native format (e.g., an outline glyph for TrueType and Type~1
+   *   formats).  [Since 2.9] The prospective bitmap metrics are
+   *   calculated according to @FT_LOAD_TARGET_XXX and other flags even
+   *   for the outline glyph, even if @FT_LOAD_RENDER is not set.
+   *
+   *   This image can later be converted into a bitmap by calling
+   *   @FT_Render_Glyph.  This function searches the current renderer for
+   *   the native image's format, then invokes it.
+   *
+   *   The renderer is in charge of transforming the native image through
+   *   the slot's face transformation fields, then converting it into a
+   *   bitmap that is returned in `slot->bitmap'.
+   *
+   *   Note that `slot->bitmap_left' and `slot->bitmap_top' are also used
+   *   to specify the position of the bitmap relative to the current pen
+   *   position (e.g., coordinates (0,0) on the baseline).  Of course,
+   *   `slot->format' is also changed to @FT_GLYPH_FORMAT_BITMAP.
+   *
+   *   Here is a small pseudo code fragment that shows how to use
+   *   `lsb_delta' and `rsb_delta' to do fractional positioning of
+   *   glyphs:
+   *
+   *   {
+   *     FT_GlyphSlot  slot     = face->glyph;
+   *     FT_Pos        origin_x = 0;
+   *
+   *
+   *     for all glyphs do
+   *       <load glyph with `FT_Load_Glyph'>

+   *       FT_Outline_Translate( slot->outline, origin_x & 63, 0 );

+   *
+   *   Here is another small pseudo code fragment that shows how to use
+   *   `lsb_delta' and `rsb_delta' to improve integer positioning of
+   *   glyphs:
+   *
+   *   {
+   *     FT_GlyphSlot  slot           = face->glyph;
+   *     FT_Pos        origin_x       = 0;
+   *     FT_Pos        prev_rsb_delta = 0;
+   *
+   *
+   *     for all glyphs do
+   *       <compute kern between current and previous glyph
+   *        and add it to `origin_x'>
+   *
+   *       <load glyph with `FT_Load_Glyph'>
+   *
+   *       if ( prev_rsb_delta - slot->lsb_delta >  32 )
+   *         origin_x -= 64;
+   *       else if ( prev_rsb_delta - slot->lsb_delta < -31 )
+   *         origin_x += 64;
+   *
+   *       prev_rsb_delta = slot->rsb_delta;
+   *
+   *       <save glyph image, or render glyph, or ...>
+   *
+   *       origin_x += slot->advance.x;
+   *     endfor
+   *   }
+   *
+   *   If you use strong auto-hinting, you *must* apply these delta
+   *   values!  Otherwise you will experience far too large inter-glyph
+   *   spacing at small rendering sizes in most cases.  Note that it
+   *   doesn't harm to use the above code for other hinting modes also,
+   *   since the delta values are zero then.

+   *
+   *   memory_base ::
+   *     The first byte of the file in memory.

+   *     The size in bytes of the file in memory.

+   *   driver ::
+   *     This field is exclusively used by @FT_Open_Face;

+   *     Extra parameters passed to the font driver when

+   *
+   * @Note:
+   *   The stream type is determined by the contents of `flags' that

+   *
+   *   If the @FT_OPEN_MEMORY bit is set, assume that this is a

+   *
+   *   Otherwise, if the @FT_OPEN_PATHNAME bit is set, assume that this

+   *     with value~0).  Set it to~0 if there is only one
+   *     face in the font file.
+   *
+   *     [Since 2.6.1] Bits 16-30 are relevant to GX and
+   *     OpenType variation fonts only, specifying the named
+   *     instance index for the current face index (starting
+   *     with value~1; value~0 makes FreeType ignore named
+   *     instances).  For non-variation fonts, bits 16-30 are
+   *     ignored.  Assuming that you want to access the third
+   *     named instance in face~4, `face_index' should be set
+   *     to 0x00030004.  If you want to access face~4 without
+   *     variation handling, simply set `face_index' to
+   *     value~4.
+   *
+   *     `FT_Open_Face' and its siblings can be used to
+   *     quickly check whether the font format of a given
+   *     font resource is supported by FreeType.  In general,
+   *     if the `face_index' argument is negative, the
+   *     function's return value is~0 if the font format is
+   *     recognized, or non-zero otherwise.  The function
+   *     allocates a more or less empty face handle in
+   *     `*aface' (if `aface' isn't NULL); the only two
+   *     useful fields in this special case are
+   *     `face->num_faces' and `face->style_flags'.  For any
+   *     negative value of `face_index', `face->num_faces'
+   *     gives the number of faces within the font file.  For
+   *     the negative value `-(N+1)' (with `N' a non-negative
+   *     16-bit value), bits 16-30 in `face->style_flags'
+   *     give the number of named instances in face `N' if we
+   *     have a variation font (or zero otherwise).  After
+   *     examination, the returned @FT_Face structure should
+   *     be deallocated with a call to @FT_Done_Face.
+   *
+   * @Output:
+   *   aface ::
+   *     A handle to a new face object.  If `face_index' is
+   *     greater than or equal to zero, it must be non-NULL.
+   *
+   * @Return:
+   *   FreeType error code.  0~means success.
+   *
+   * @Note:
+   *   Unlike FreeType 1.x, this function automatically creates a glyph
+   *   slot for the face object that can be accessed directly through
+   *   `face->glyph'.
+   *
+   *   Each new face object created with this function also owns a
+   *   default @FT_Size object, accessible as `face->size'.
+   *
+   *   One @FT_Library instance can have multiple face objects, this is,
+   *   @FT_Open_Face and its siblings can be called multiple times using
+   *   the same `library' argument.
+   *
+   *   See the discussion of reference counters in the description of
+   *   @FT_Reference_Face.
+   *
+   *   To loop over all faces, use code similar to the following snippet
+   *   (omitting the error handling).
+   *
+   *   {
+   *     ...
+   *     FT_Face  face;
+   *     FT_Long  i, num_faces;
+   *
+   *
+   *     error = FT_Open_Face( library, args, -1, &face );
+   *     if ( error ) { ... }
+   *
+   *     num_faces = face->num_faces;
+   *     FT_Done_Face( face );
+   *
+   *     for ( i = 0; i < num_faces; i++ )
+   *     {
+   *       ...
+   *       error = FT_Open_Face( library, args, i, &face );
+   *       ...
+   *       FT_Done_Face( face );
+   *       ...
+   *     }
+   *   }
+   *
+   *   To loop over all valid values for `face_index', use something
+   *   similar to the following snippet, again without error handling.
+   *   The code accesses all faces immediately (thus only a single call
+   *   of `FT_Open_Face' within the do-loop), with and without named
+   *   instances.
+   *
+   *   {
+   *     ...
+   *     FT_Face  face;
+   *
+   *     FT_Long  num_faces     = 0;

+   *     A pointer to the translation vector.  Use NULL for the
+   *     null vector.
+   *
+   * @Note:
+   *   The transformation is only applied to scalable image formats after

+   * @Function:
+   *   FT_Render_Glyph
+   *
+   * @Description:
+   *   Convert a given glyph image to a bitmap.  It does so by inspecting
+   *   the glyph image format, finding the relevant renderer, and
+   *   invoking it.
+   *
+   * @InOut:
+   *   slot ::
+   *     A handle to the glyph slot containing the image to
+   *     convert.
+   *
+   * @Input:
+   *   render_mode ::
+   *     The render mode used to render the glyph image into
+   *     a bitmap.  See @FT_Render_Mode for a list of
+   *     possible values.
+   *
+   *     If @FT_RENDER_MODE_NORMAL is used, the flag
+   *     @FT_LOAD_COLOR can be additionally set to make the
+   *     function provide a default blending of colored
+   *     glyph layers associated with the current glyph slot
+   *     (provided the font contains such layers) instead of
+   *     rendering the glyph slot's outline.  See
+   *     @FT_LOAD_COLOR for more information.
+   *
+   * @Return:
+   *   FreeType error code.  0~means success.
+   *
+   * @Note:
+   *   To get meaningful results, font scaling values must be set with
+   *   functions like @FT_Set_Char_Size before calling `FT_Render_Glyph'.
+   *
+   *   When FreeType outputs a bitmap of a glyph, it really outputs an
+   *   alpha coverage map.  If a pixel is completely covered by a
+   *   filled-in outline, the bitmap contains 0xFF at that pixel, meaning
+   *   that 0xFF/0xFF fraction of that pixel is covered, meaning the
+   *   pixel is 100% black (or 0% bright).  If a pixel is only 50%
+   *   covered (value 0x80), the pixel is made 50% black (50% bright or a
+   *   middle shade of grey).  0% covered means 0% black (100% bright or
+   *   white).
+   *
+   *   On high-DPI screens like on smartphones and tablets, the pixels
+   *   are so small that their chance of being completely covered and
+   *   therefore completely black are fairly good.  On the low-DPI
+   *   screens, however, the situation is different.  The pixels are too
+   *   large for most of the details of a glyph and shades of gray are
+   *   the norm rather than the exception.
+   *
+   *   This is relevant because all our screens have a second problem:
+   *   they are not linear.  1~+~1 is not~2.  Twice the value does not
+   *   result in twice the brightness.  When a pixel is only 50% covered,
+   *   the coverage map says 50% black, and this translates to a pixel
+   *   value of 128 when you use 8~bits per channel (0-255).  However,
+   *   this does not translate to 50% brightness for that pixel on our
+   *   sRGB and gamma~2.2 screens.  Due to their non-linearity, they
+   *   dwell longer in the darks and only a pixel value of about 186
+   *   results in 50% brightness -- 128 ends up too dark on both bright
+   *   and dark backgrounds.  The net result is that dark text looks
+   *   burnt-out, pixely and blotchy on bright background, bright text
+   *   too frail on dark backgrounds, and colored text on colored
+   *   background (for example, red on green) seems to have dark halos or
+   *   `dirt' around it.  The situation is especially ugly for diagonal
+   *   stems like in `w' glyph shapes where the quality of FreeType's
+   *   anti-aliasing depends on the correct display of grays.  On
+   *   high-DPI screens where smaller, fully black pixels reign supreme,
+   *   this doesn't matter, but on our low-DPI screens with all the gray
+   *   shades, it does.  0% and 100% brightness are the same things in
+   *   linear and non-linear space, just all the shades in-between
+   *   aren't.
+   *
+   *   The blending function for placing text over a background is
+   *
+   *   {
+   *     dst = alpha * src + (1 - alpha) * dst    ,
+   *   }
+   *
+   *   which is known as the OVER operator.
+   *
+   *   To correctly composite an antialiased pixel of a glyph onto a
+   *   surface,
+   *
+   *   1. take the foreground and background colors (e.g., in sRGB space)
+   *      and apply gamma to get them in a linear space,
+   *
+   *   2. use OVER to blend the two linear colors using the glyph pixel
+   *      as the alpha value (remember, the glyph bitmap is an alpha
+   *      coverage bitmap), and
+   *
+   *   3. apply inverse gamma to the blended pixel and write it back to
+   *      the image.
+   *
+   *   Internal testing at Adobe found that a target inverse gamma of~1.8
+   *   for step~3 gives good results across a wide range of displays with
+   *   an sRGB gamma curve or a similar one.
+   *
+   *   This process can cost performance.  There is an approximation that
+   *   does not need to know about the background color; see
+   *   https://bel.fi/alankila/lcd/ and
+   *   https://bel.fi/alankila/lcd/alpcor.html for details.
+   *
+   *   *ATTENTION*: Linear blending is even more important when dealing
+   *   with subpixel-rendered glyphs to prevent color-fringing!  A
+   *   subpixel-rendered glyph must first be filtered with a filter that
+   *   gives equal weight to the three color primaries and does not
+   *   exceed a sum of 0x100, see section @lcd_filtering.  Then the
+   *   only difference to gray linear blending is that subpixel-rendered

+   *
+   * @Description:
+   *   Return the first character code in the current charmap of a given
+   *   face, together with its corresponding glyph index.
+   *
+   * @Input:
+   *   face ::
+   *     A handle to the source face object.
+   *
+   * @Output:
+   *   agindex ::
+   *     Glyph index of first character code.  0~if charmap is
+   *     empty.
+   *
+   * @Return:
+   *   The charmap's first character code.
+   *
+   * @Note:
+   *   You should use this function together with @FT_Get_Next_Char to
+   *   parse all character codes available in a given charmap.  The code
+   *   should look like this:
+   *
+   *   {
+   *     FT_ULong  charcode;
+   *     FT_UInt   gindex;
+   *
+   *
+   *     charcode = FT_Get_First_Char( face, &gindex );
+   *     while ( gindex != 0 )
+   *     {
+   *       ... do something with (charcode,gindex) pair ...
+   *
+   *       charcode = FT_Get_Next_Char( face, charcode, &gindex );
+   *     }
+   *   }
+   *
+   *   Be aware that character codes can have values up to 0xFFFFFFFF;
+   *   this might happen for non-Unicode or malformed cmaps.  However,
+   *   even with regular Unicode encoding, so-called `last resort fonts'
+   *   (using SFNT cmap format 13, see function @FT_Get_CMap_Format)
+   *   normally have entries for all Unicode characters up to 0x1FFFFF,
+   *   which can cause *a lot* of iterations.
+   *
+   *   Note that `*agindex' is set to~0 if the charmap is empty.  The
+   *   result itself can be~0 in two cases: if the charmap is empty or
+   *   if the value~0 is the first valid character code.

+   *   useful when dynamically linking to the library, since one cannot
+   *   use the macros @FREETYPE_MAJOR, @FREETYPE_MINOR, and
+   *   @FREETYPE_PATCH.
+   *
+   * @Input:
+   *   library ::
+   *     A source library handle.
+   *
+   * @Output:
+   *   amajor ::
+   *     The major version number.
+   *
+   *   aminor ::
+   *     The minor version number.
+   *
+   *   apatch ::
+   *     The patch version number.
+   *
+   * @Note:
+   *   The reason why this function takes a `library' argument is because
+   *   certain programs implement library initialization in a custom way
+   *   that doesn't use @FT_Init_FreeType.
+   *
+   *   In such cases, the library version might not be available before
+   *   the library object has been created.

+   * @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
+   *  }
+   *
+   *  Note that `FT_Err_Ok' is _not_ defined with `FT_ERRORDEF' but with
+   *  `FT_NOERRORDEF'; it is always zero.

+   * @Function:
+   *   FT_Glyph_Get_CBox
+   *
+   * @Description:
+   *   Return a glyph's `control box'.  The control box encloses all the
+   *   outline's points, including Bezier control points.  Though it
+   *   coincides with the exact bounding box for most glyphs, it can be
+   *   slightly larger in some situations (like when rotating an outline
+   *   that contains Bezier outside arcs).
+   *
+   *   Computing the control box is very fast, while getting the bounding
+   *   box can take much more time as it needs to walk over all segments
+   *   and arcs in the outline.  To get the latter, you can use the
+   *   `ftbbox' component, which is dedicated to this single task.
+   *
+   * @Input:
+   *   glyph ::
+   *     A handle to the source glyph object.
+   *
+   *   mode ::
+   *     The mode that indicates how to interpret the returned
+   *     bounding box values.
+   *
+   * @Output:
+   *   acbox ::
+   *     The glyph coordinate bounding box.  Coordinates are
+   *     expressed in 1/64th of pixels if it is grid-fitted.
+   *
+   * @Note:
+   *   Coordinates are relative to the glyph origin, using the y~upwards
+   *   convention.
+   *
+   *   If the glyph has been loaded with @FT_LOAD_NO_SCALE, `bbox_mode'
+   *   must be set to @FT_GLYPH_BBOX_UNSCALED to get unscaled font
+   *   units in 26.6 pixel format.  The value @FT_GLYPH_BBOX_SUBPIXELS
+   *   is another name for this constant.
+   *
+   *   If the font is tricky and the glyph has been loaded with
+   *   @FT_LOAD_NO_SCALE, the resulting CBox is meaningless.  To get
+   *   reasonable values for the CBox it is necessary to load the glyph
+   *   at a large ppem value (so that the hinting instructions can
+   *   properly shift and scale the subglyphs), then extracting the CBox,
+   *   which can be eventually converted back to font units.
+   *
+   *   Note that the maximum coordinates are exclusive, which means that
+   *   one can compute the width and height of the glyph image (be it in
+   *   integer or 26.6 pixels) as:
+   *
+   *   {
+   *     width  = bbox.xMax - bbox.xMin;
+   *     height = bbox.yMax - bbox.yMin;
+   *   }
+   *
+   *   Note also that for 26.6 coordinates, if `bbox_mode' is set to
+   *   @FT_GLYPH_BBOX_GRIDFIT, the coordinates will also be grid-fitted,
+   *   which corresponds to:
+   *
+   *   {
+   *     bbox.xMin = FLOOR(bbox.xMin);
+   *     bbox.yMin = FLOOR(bbox.yMin);
+   *     bbox.xMax = CEILING(bbox.xMax);
+   *     bbox.yMax = CEILING(bbox.yMax);
+   *   }
+   *
+   *   To get the bbox in pixel coordinates, set `bbox_mode' to
+   *   @FT_GLYPH_BBOX_TRUNCATE.
+   *
+   *   To get the bbox in grid-fitted pixel coordinates, set `bbox_mode'
+   *   to @FT_GLYPH_BBOX_PIXELS.

+   *
+   * @Function:
+   *   FT_Glyph_To_Bitmap
+   *
+   * @Description:
+   *   Convert a given glyph object to a bitmap glyph object.
+   *
+   * @InOut:
+   *   the_glyph ::
+   *     A pointer to a handle to the target glyph.
+   *
+   * @Input:
+   *   render_mode ::
+   *     An enumeration that describes how the data is
+   *     rendered.
+   *
+   *   origin ::
+   *     A pointer to a vector used to translate the glyph
+   *     image before rendering.  Can be~0 (if no
+   *     translation).  The origin is expressed in
+   *     26.6 pixels.
+   *
+   *   destroy ::
+   *     A boolean that indicates that the original glyph
+   *     image should be destroyed by this function.  It is
+   *     never destroyed in case of error.
+   *
+   * @Return:
+   *   FreeType error code.  0~means success.
+   *
+   * @Note:
+   *   This function does nothing if the glyph format isn't scalable.
+   *
+   *   The glyph image is translated with the `origin' vector before
+   *   rendering.
+   *
+   *   The first parameter is a pointer to an @FT_Glyph handle, that will
+   *   be _replaced_ by this function (with newly allocated data).
+   *   Typically, you would use (omitting error handling):
+   *
+   *
+   *     {
+   *       FT_Glyph        glyph;
+   *       FT_BitmapGlyph  glyph_bitmap;
+   *
+   *
+   *       // load glyph
+   *       error = FT_Load_Char( face, glyph_index, FT_LOAD_DEFAULT );
+   *
+   *       // extract glyph image
+   *       error = FT_Get_Glyph( face->glyph, &glyph );
+   *
+   *       // convert to a bitmap (default render mode + destroying old)
+   *       if ( glyph->format != FT_GLYPH_FORMAT_BITMAP )
+   *       {
+   *         error = FT_Glyph_To_Bitmap( &glyph, FT_RENDER_MODE_NORMAL,
+   *                                     0, 1 );
+   *         if ( error ) // `glyph' unchanged
+   *           ...
+   *       }
+   *
+   *       // access bitmap content by typecasting
+   *       glyph_bitmap = (FT_BitmapGlyph)glyph;
+   *
+   *       // do funny stuff with it, like blitting/drawing
+   *       ...
+   *
+   *       // discard glyph image (bitmap or not)
+   *       FT_Done_Glyph( glyph );
+   *     }
+   *
+   *
+   *   Here another example, again without error handling:
+   *
+   *
+   *     {
+   *       FT_Glyph  glyphs[MAX_GLYPHS]
+   *
+   *
+   *       ...
+   *

+   *

+   *
+   *         // after this call, `bitmap' no longer points into
+   *         // the `glyphs' array (and the old value isn't destroyed)

+   * @Struct:
+   *   FT_Bitmap
+   *
+   * @Description:
+   *   A structure used to describe a bitmap or pixmap to the raster.
+   *   Note that we now manage pixmaps of various depths through the
+   *   `pixel_mode' field.
+   *
+   * @Fields:
+   *   rows ::
+   *     The number of bitmap rows.
+   *
+   *   width ::
+   *     The number of pixels in bitmap row.
+   *
+   *   pitch ::
+   *     The pitch's absolute value is the number of bytes
+   *     taken by one bitmap row, including padding.
+   *     However, the pitch is positive when the bitmap has
+   *     a `down' flow, and negative when it has an `up'
+   *     flow.  In all cases, the pitch is an offset to add
+   *     to a bitmap pointer in order to go down one row.
+   *
+   *     Note that `padding' means the alignment of a
+   *     bitmap to a byte border, and FreeType functions
+   *     normally align to the smallest possible integer
+   *     value.
+   *
+   *     For the B/W rasterizer, `pitch' is always an even
+   *     number.
+   *
+   *     To change the pitch of a bitmap (say, to make it a
+   *     multiple of 4), use @FT_Bitmap_Convert.
+   *     Alternatively, you might use callback functions to
+   *     directly render to the application's surface; see
+   *     the file `example2.cpp' in the tutorial for a
+   *     demonstration.
+   *
+   *   buffer ::
+   *     A typeless pointer to the bitmap buffer.  This
+   *     value should be aligned on 32-bit boundaries in
+   *     most cases.
+   *
+   *   num_grays ::
+   *     This field is only used with
+   *     @FT_PIXEL_MODE_GRAY; it gives the number of gray
+   *     levels used in the bitmap.
+   *
+   *   pixel_mode ::
+   *     The pixel mode, i.e., how pixel bits are stored.
+   *     See @FT_Pixel_Mode for possible values.
+   *
+   *   palette_mode ::
+   *     This field is intended for paletted pixel modes;
+   *     it indicates how the palette is stored.  Not
+   *     used currently.
+   *
+   *   palette ::
+   *     A typeless pointer to the bitmap palette; this
+   *     field is intended for paletted pixel modes.  Not
+   *     used currently.

+   * @Enum:
+   *   FT_OUTLINE_XXX
+   *
+   * @Description:
+   *   A list of bit-field constants use for the flags in an outline's
+   *   `flags' field.
+   *
+   * @Values:
+   *   FT_OUTLINE_NONE ::
+   *     Value~0 is reserved.
+   *
+   *   FT_OUTLINE_OWNER ::
+   *     If set, this flag indicates that the outline's field arrays
+   *     (i.e., `points', `flags', and `contours') are `owned' by the
+   *     outline object, and should thus be freed when it is destroyed.
+   *
+   *   FT_OUTLINE_EVEN_ODD_FILL ::
+   *     By default, outlines are filled using the non-zero winding rule.
+   *     If set to 1, the outline will be filled using the even-odd fill
+   *     rule (only works with the smooth rasterizer).
+   *
+   *   FT_OUTLINE_REVERSE_FILL ::
+   *     By default, outside contours of an outline are oriented in
+   *     clock-wise direction, as defined in the TrueType specification.
+   *     This flag is set if the outline uses the opposite direction
+   *     (typically for Type~1 fonts).  This flag is ignored by the scan
+   *     converter.
+   *
+   *   FT_OUTLINE_IGNORE_DROPOUTS ::
+   *     By default, the scan converter will try to detect drop-outs in
+   *     an outline and correct the glyph bitmap to ensure consistent
+   *     shape continuity.  If set, this flag hints the scan-line
+   *     converter to ignore such cases.  See below for more information.
+   *
+   *   FT_OUTLINE_SMART_DROPOUTS ::
+   *     Select smart dropout control.  If unset, use simple dropout
+   *     control.  Ignored if @FT_OUTLINE_IGNORE_DROPOUTS is set.  See
+   *     below for more information.
+   *
+   *   FT_OUTLINE_INCLUDE_STUBS ::
+   *     If set, turn pixels on for `stubs', otherwise exclude them.
+   *     Ignored if @FT_OUTLINE_IGNORE_DROPOUTS is set.  See below for
+   *     more information.
+   *
+   *   FT_OUTLINE_HIGH_PRECISION ::
+   *     This flag indicates that the scan-line converter should try to
+   *     convert this outline to bitmaps with the highest possible
+   *     quality.  It is typically set for small character sizes.  Note
+   *     that this is only a hint that might be completely ignored by a
+   *     given scan-converter.
+   *
+   *   FT_OUTLINE_SINGLE_PASS ::
+   *     This flag is set to force a given scan-converter to only use a
+   *     single pass over the outline to render a bitmap glyph image.
+   *     Normally, it is set for very large character sizes.  It is only
+   *     a hint that might be completely ignored by a given
+   *     scan-converter.
+   *
+   * @Note:
+   *   The flags @FT_OUTLINE_IGNORE_DROPOUTS, @FT_OUTLINE_SMART_DROPOUTS,
+   *   and @FT_OUTLINE_INCLUDE_STUBS are ignored by the smooth
+   *   rasterizer.
+   *
+   *   There exists a second mechanism to pass the drop-out mode to the
+   *   B/W rasterizer; see the `tags' field in @FT_Outline.
+   *
+   *   Please refer to the description of the `SCANTYPE' instruction in

+   *   their own format.
+   *
+   * @Values:
+   *   FT_GLYPH_FORMAT_NONE ::

+   *
+   *   FT_GLYPH_FORMAT_COMPOSITE ::
+   *     The glyph image is a composite of several other images.  This
+   *     format is _only_ used with @FT_LOAD_NO_RECURSE, and is used to
+   *     report compound glyphs (like accented characters).
+   *
+   *   FT_GLYPH_FORMAT_BITMAP ::
+   *     The glyph image is a bitmap, and can be described as an

+   *   FT_GLYPH_FORMAT_OUTLINE ::
+   *     The glyph image is a vectorial outline made of line segments

+   *     @FT_GlyphSlotRec structure to read it.
+   *
+   *   FT_GLYPH_FORMAT_PLOTTER ::
+   *     The glyph image is a vectorial path with no inside and outside

+   *   count ::
+   *     The number of spans to draw on this scanline.

+   *   user ::
