- * @property:
- * glyph-to-script-map
- *
- * @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 );
- *
- * // adjust `prop.map' as needed right here
- *
- * FT_Load_Glyph( face, ..., FT_LOAD_FORCE_AUTOHINT );

- * 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 `light' auto-hinting mode. 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;
- *
- *
- * FT_Init_FreeType( &library );
- *
- * FT_Property_Set( library, "autofitter",
- * "warping", &warping );
- * }
- *
- * @note:
- * This property can be used with @FT_Property_Get also.
- *
- * 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 `light' hinting mode.

- *
- * <Title>
- * Cache Sub-System
- *
- * <Abstract>
- * How to cache face, size, and glyph data with FreeType~2.
- *
- * <Description>
- * This section describes the FreeType~2 cache sub-system, which is used
- * to limit the number of concurrently opened @FT_Face and @FT_Size
- * objects, as well as caching information like character maps and glyph
- * images while limiting their maximum memory usage.
- *
- * Note that all types and functions begin with the `FTC_' prefix.
- *
- * The cache is highly portable and thus doesn't know anything about the
- * fonts installed on your system, or how to access them. This implies
- * the following scheme:
- *
- * First, available or installed font faces are uniquely identified by
- * @FTC_FaceID values, provided to the cache by the client. Note that
- * the cache only stores and compares these values, and doesn't try to
- * interpret them in any way.
- *
- * Second, the cache calls, only when needed, a client-provided function
- * to convert an @FTC_FaceID into a new @FT_Face object. The latter is
- * then completely managed by the cache, including its termination
- * through @FT_Done_Face. To monitor termination of face objects, the
- * finalizer callback in the `generic' field of the @FT_Face object can
- * be used, which might also be used to store the @FTC_FaceID of the
- * face.
- *
- * Clients are free to map face IDs to anything else. The most simple
- * usage is to associate them to a (pathname,face_index) pair that is
- * used to call @FT_New_Face. However, more complex schemes are also
- * possible.
- *
- * Note that for the cache to work correctly, the face ID values must be
- * *persistent*, which means that the contents they point to should not
- * change at runtime, or that their value should not become invalid.
- *
- * If this is unavoidable (e.g., when a font is uninstalled at runtime),
- * you should call @FTC_Manager_RemoveFaceID as soon as possible, to let
- * the cache get rid of any references to the old @FTC_FaceID it may
- * keep internally. Failure to do so will lead to incorrect behaviour
- * or even crashes.
- *
- * To use the cache, start with calling @FTC_Manager_New to create a new
- * @FTC_Manager object, which models a single cache instance. You can
- * then look up @FT_Face and @FT_Size objects with
- * @FTC_Manager_LookupFace and @FTC_Manager_LookupSize, respectively.
- *
- * If you want to use the charmap caching, call @FTC_CMapCache_New, then
- * later use @FTC_CMapCache_Lookup to perform the equivalent of
- * @FT_Get_Char_Index, only much faster.
- *
- * If you want to use the @FT_Glyph caching, call @FTC_ImageCache, then
- * later use @FTC_ImageCache_Lookup to retrieve the corresponding
- * @FT_Glyph objects from the cache.
- *
- * If you need lots of small bitmaps, it is much more memory efficient
- * to call @FTC_SBitCache_New followed by @FTC_SBitCache_Lookup. This
- * returns @FTC_SBitRec structures, which are used to store small
- * bitmaps directly. (A small bitmap is one whose metrics and
- * dimensions all fit into 8-bit integers).
- *
- * We hope to also provide a kerning cache in the near future.

- *
- * @description:
- * A list of valid values for the `charset' byte in
- * @FT_WinFNT_HeaderRec. Exact mapping tables for the various cpXXXX
- * encodings (except for cp1361) can be found at
- * ftp://ftp.unicode.org/Public in the MAPPINGS/VENDORS/MICSFT/WINDOWS
- * subdirectory. cp1361 is roughly a superset of
- * MAPPINGS/OBSOLETE/EASTASIA/KSC/JOHAB.TXT.
- *
- * @values:
- * FT_WinFNT_ID_DEFAULT ::
- * This is used for font enumeration and font creation as a
- * `don't care' value. Valid font files don't contain this value.
- * When querying for information about the character set of the font
- * that is currently selected into a specified device context, this
- * return value (of the related Windows API) simply denotes failure.
- *
- * FT_WinFNT_ID_SYMBOL ::
- * There is no known mapping table available.
- *
- * FT_WinFNT_ID_MAC ::
- * Mac Roman encoding.
- *
- * FT_WinFNT_ID_OEM ::
- * From Michael Pöttgen <michael@poettgen.de>:
- *
- * The `Windows Font Mapping' article says that FT_WinFNT_ID_OEM
- * is used for the charset of vector fonts, like `modern.fon',
- * `roman.fon', and `script.fon' on Windows.
- *
- * The `CreateFont' documentation says: The FT_WinFNT_ID_OEM value
- * specifies a character set that is operating-system dependent.
- *
- * The `IFIMETRICS' documentation from the `Windows Driver
- * Development Kit' says: This font supports an OEM-specific
- * character set. The OEM character set is system dependent.
- *
- * In general OEM, as opposed to ANSI (i.e., cp1252), denotes the
- * second default codepage that most international versions of
- * Windows have. It is one of the OEM codepages from
- *
- * https://msdn.microsoft.com/en-us/goglobal/bb964655,
- *
- * and is used for the `DOS boxes', to support legacy applications.
- * A German Windows version for example usually uses ANSI codepage
- * 1252 and OEM codepage 850.
- *
- * FT_WinFNT_ID_CP874 ::
- * A superset of Thai TIS 620 and ISO 8859-11.
- *
- * FT_WinFNT_ID_CP932 ::
- * A superset of Japanese Shift-JIS (with minor deviations).
- *
- * FT_WinFNT_ID_CP936 ::
- * A superset of simplified Chinese GB 2312-1980 (with different
- * ordering and minor deviations).
- *
- * FT_WinFNT_ID_CP949 ::
- * A superset of Korean Hangul KS~C 5601-1987 (with different
- * ordering and minor deviations).
- *
- * FT_WinFNT_ID_CP950 ::
- * A superset of traditional Chinese Big~5 ETen (with different
- * ordering and minor deviations).
- *
- * FT_WinFNT_ID_CP1250 ::
- * A superset of East European ISO 8859-2 (with slightly different
- * ordering).
- *
- * FT_WinFNT_ID_CP1251 ::
- * A superset of Russian ISO 8859-5 (with different ordering).
- *
- * FT_WinFNT_ID_CP1252 ::
- * ANSI encoding. A superset of ISO 8859-1.
- *
- * FT_WinFNT_ID_CP1253 ::
- * A superset of Greek ISO 8859-7 (with minor modifications).
- *
- * FT_WinFNT_ID_CP1254 ::
- * A superset of Turkish ISO 8859-9.
- *
- * FT_WinFNT_ID_CP1255 ::
- * A superset of Hebrew ISO 8859-8 (with some modifications).
- *
- * FT_WinFNT_ID_CP1256 ::
- * A superset of Arabic ISO 8859-6 (with different ordering).
- *
- * FT_WinFNT_ID_CP1257 ::
- * A superset of Baltic ISO 8859-13 (with some deviations).
- *
- * FT_WinFNT_ID_CP1258 ::
- * For Vietnamese. This encoding doesn't cover all necessary
- * characters.
- *
- * FT_WinFNT_ID_CP1361 ::

- Notes
-
- Mac suitcase files can (and often do!) contain multiple fonts. To
- support this I use the face_index argument of FT_(Open|New)_Face()
- functions, and pretend the suitcase file is a collection.
-
- Warning: fbit and NFNT bitmap resources are not supported yet. In old
- sfnt fonts, bitmap glyph data for each size is stored in each `NFNT'
- resources instead of the `bdat' table in the sfnt resource. Therefore,
- face->num_fixed_sizes is set to 0, because bitmap data in `NFNT'
- resource is unavailable at present.
-
- The Mac FOND support works roughly like this:
-
- - Check whether the offered stream points to a Mac suitcase file. This
- is done by checking the file type: it has to be 'FFIL' or 'tfil'. The
- stream that gets passed to our init_face() routine is a stdio stream,
- which isn't usable for us, since the FOND resources live in the
- resource fork. So we just grab the stream->pathname field.
-
- - Read the FOND resource into memory, then check whether there is a
- TrueType font and/or(!) a Type 1 font available.
-
- - If there is a Type 1 font available (as a separate `LWFN' file), read
- its data into memory, massage it slightly so it becomes PFB data, wrap
- it into a memory stream, load the Type 1 driver and delegate the rest
- of the work to it by calling FT_Open_Face(). (XXX TODO: after this
- has been done, the kerning data from the FOND resource should be
- appended to the face: On the Mac there are usually no AFM files
- available. However, this is tricky since we need to map Mac char
- codes to ps glyph names to glyph ID's...)
-
- - If there is a TrueType font (an `sfnt' resource), read it into memory,
- wrap it into a memory stream, load the TrueType driver and delegate
- the rest of the work to it, by calling FT_Open_Face().
-
- - Some suitcase fonts (notably Onyx) might point the `LWFN' file to
- itself, even though it doesn't contains `POST' resources. To handle
- this special case without opening the file an extra time, we just
- ignore errors from the `LWFN' and fallback to the `sfnt' if both are
- available.
