/* FT_FACE_FLAG_HINTER :: */

/* (with the bytecode interpreter) is available and active. */
/* */
/* FT_FACE_FLAG_CID_KEYED :: */
/* Set if the font is CID-keyed. In that case, the font is not */

/* CID-keyed fonts this has the consequence that not all index */
/* values are a valid argument to FT_Load_Glyph. Only the CID */

/* */
/* FT_FACE_FLAG_TRICKY :: */
/* Set if the font is `tricky', this is, it always needs the */
/* font format's native hinting engine to get a reasonable result. */
/* A typical example is the Chinese font `mingli.ttf' which uses */
/* TrueType bytecode instructions to move and scale all of its */
/* subglyphs. */
/* */
/* It is not possible to autohint such fonts using */
/* @FT_LOAD_FORCE_AUTOHINT; it will also ignore */
/* @FT_LOAD_NO_HINTING. You have to set both @FT_LOAD_NO_HINTING */

/*************************************************************************
*
* @enum:
* FT_LOAD_XXX
*
* @description:
* A list of bit-field constants used with @FT_Load_Glyph to indicate
* what kind of operations to perform during glyph loading.
*
* @values:
* FT_LOAD_DEFAULT ::
* Corresponding to~0, this value is used as the default glyph load
* operation. In this case, the following happens:
*
* 1. FreeType looks for a bitmap for the glyph corresponding to the
* face's current size. If one is found, the function returns.
* The bitmap data can be accessed from the glyph slot (see note
* below).
*
* 2. If no embedded bitmap is searched or found, FreeType looks for a
* scalable outline. If one is found, it is loaded from the font
* file, scaled to device pixels, then `hinted' to the pixel grid
* in order to optimize it. The outline data can be accessed from
* the glyph slot (see note below).
*
* Note that by default, the glyph loader doesn't render outlines into
* bitmaps. The following flags are used to modify this default
* behaviour to more specific and useful cases.
*
* FT_LOAD_NO_SCALE ::
* Don't scale the loaded outline glyph but keep it in font units.
*
* This flag implies @FT_LOAD_NO_HINTING and @FT_LOAD_NO_BITMAP, and
* unsets @FT_LOAD_RENDER.
*
* If the font is `tricky' (see @FT_FACE_FLAG_TRICKY for more), using
* FT_LOAD_NO_SCALE usually yields meaningless outlines because the
* subglyphs must be scaled and positioned with hinting instructions.
* This can be solved by loading the font without FT_LOAD_NO_SCALE and
* setting the character size to `font->units_per_EM'.
*
* FT_LOAD_NO_HINTING ::
* Disable hinting. This generally generates `blurrier' bitmap glyphs
* when the glyph are rendered in any of the anti-aliased modes. See
* also the note below.
*
* This flag is implied by @FT_LOAD_NO_SCALE.
*
* FT_LOAD_RENDER ::
* Call @FT_Render_Glyph after the glyph is loaded. By default, the
* glyph is rendered in @FT_RENDER_MODE_NORMAL mode. This can be
* overridden by @FT_LOAD_TARGET_XXX or @FT_LOAD_MONOCHROME.
*
* This flag is unset by @FT_LOAD_NO_SCALE.
*
* FT_LOAD_NO_BITMAP ::
* Ignore bitmap strikes when loading. Bitmap-only fonts ignore this
* flag.
*
* @FT_LOAD_NO_SCALE always sets this flag.
*
* FT_LOAD_VERTICAL_LAYOUT ::
* Load the glyph for vertical text layout. In particular, the
* `advance' value in the @FT_GlyphSlotRec structure is set to the
* `vertAdvance' value of the `metrics' field.
*
* In case @FT_HAS_VERTICAL doesn't return true, you shouldn't use
* this flag currently. Reason is that in this case vertical metrics
* get synthesized, and those values are not always consistent across
* various font formats.
*
* FT_LOAD_FORCE_AUTOHINT ::
* Indicates that the auto-hinter is preferred over the font's native
* hinter. See also the note below.
*
* FT_LOAD_CROP_BITMAP ::
* Indicates that the font driver should crop the loaded bitmap glyph
* (i.e., remove all space around its black bits). Not all drivers
* implement this.
*
* FT_LOAD_PEDANTIC ::
* Indicates that the font driver should perform pedantic verifications
* during glyph loading. This is mostly used to detect broken glyphs
* in fonts. By default, FreeType tries to handle broken fonts also.
*
* In particular, errors from the TrueType bytecode engine are not
* passed to the application if this flag is not set; this might
* result in partially hinted or distorted glyphs in case a glyph's
* bytecode is buggy.
*
* FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH ::
* Ignored. Deprecated.
*
* FT_LOAD_NO_RECURSE ::
* This flag is only used internally. It merely indicates that the
* font driver should not load composite glyphs recursively. Instead,
* it should set the `num_subglyph' and `subglyphs' values of the
* glyph slot accordingly, and set `glyph->format' to
* @FT_GLYPH_FORMAT_COMPOSITE.
*
* The description of sub-glyphs is not available to client
* applications for now.
*
* This flag implies @FT_LOAD_NO_SCALE and @FT_LOAD_IGNORE_TRANSFORM.
*
* FT_LOAD_IGNORE_TRANSFORM ::
* Indicates that the transform matrix set by @FT_Set_Transform should
* be ignored.
*
* FT_LOAD_MONOCHROME ::
* This flag is used with @FT_LOAD_RENDER to indicate that you want to
* render an outline glyph to a 1-bit monochrome bitmap glyph, with
* 8~pixels packed into each byte of the bitmap data.
*
* Note that this has no effect on the hinting algorithm used. You
* should rather use @FT_LOAD_TARGET_MONO so that the
* monochrome-optimized hinting algorithm is used.
*
* FT_LOAD_LINEAR_DESIGN ::
* Indicates that the `linearHoriAdvance' and `linearVertAdvance'
* fields of @FT_GlyphSlotRec should be kept in font units. See
* @FT_GlyphSlotRec for details.
*
* FT_LOAD_NO_AUTOHINT ::
* Disable auto-hinter. See also the note below.
*
* FT_LOAD_COLOR ::
* This flag is used to request loading of color embedded-bitmap
* images. The resulting color bitmaps, if available, will have the
* @FT_PIXEL_MODE_BGRA format. When the flag is not used and color
* bitmaps are found, they will be converted to 256-level gray
* bitmaps transparently. Those bitmaps will be in the
* @FT_PIXEL_MODE_GRAY format.
*
* @note:
* By default, hinting is enabled and the font's native hinter (see
* @FT_FACE_FLAG_HINTER) is preferred over the auto-hinter. You can
* disable hinting by setting @FT_LOAD_NO_HINTING or change the
* precedence by setting @FT_LOAD_FORCE_AUTOHINT. You can also set
* @FT_LOAD_NO_AUTOHINT in case you don't want the auto-hinter to be
* used at all.
*
* See the description of @FT_FACE_FLAG_TRICKY for a special exception
* (affecting only a handful of Asian fonts).
*
* Besides deciding which hinter to use, you can also decide which
* hinting algorithm to use. See @FT_LOAD_TARGET_XXX for details.
*
* Note that the auto-hinter needs a valid Unicode cmap (either a native
* one or synthesized by FreeType) for producing correct results. If a
* font provides an incorrect mapping (for example, assigning the
* character code U+005A, LATIN CAPITAL LETTER Z, to a glyph depicting a
* mathematical integral sign), the auto-hinter might produce useless
* results.

* @description:
* A list of values that are used to select a specific hinting algorithm
* to use by the hinter. You should OR one of these values to your
* `load_flags' when calling @FT_Load_Glyph.
*
* Note that font's native hinters may ignore the hinting algorithm you
* have specified (e.g., the TrueType bytecode interpreter). You can set
* @FT_LOAD_FORCE_AUTOHINT to ensure that the auto-hinter is used.
*
* Also note that @FT_LOAD_TARGET_LIGHT is an exception, in that it
* always implies @FT_LOAD_FORCE_AUTOHINT.
*
* @values:
* FT_LOAD_TARGET_NORMAL ::
* This corresponds to the default hinting algorithm, optimized for
* standard gray-level rendering. For monochrome output, use
* @FT_LOAD_TARGET_MONO instead.
*
* FT_LOAD_TARGET_LIGHT ::
* A lighter hinting algorithm for non-monochrome modes. Many
* generated glyphs are more fuzzy but better resemble its original
* shape. A bit like rendering on Mac OS~X.
*
* As a special exception, this target implies @FT_LOAD_FORCE_AUTOHINT.
*
* FT_LOAD_TARGET_MONO ::
* Strong hinting algorithm that should only be used for monochrome
* output. The result is probably unpleasant if the glyph is rendered
* in non-monochrome modes.
*
* FT_LOAD_TARGET_LCD ::
* A variant of @FT_LOAD_TARGET_NORMAL optimized for horizontally
* decimated LCD displays.
*
* FT_LOAD_TARGET_LCD_V ::
* A variant of @FT_LOAD_TARGET_NORMAL optimized for vertically
* decimated LCD displays.
*
* @note:
* You should use only _one_ of the FT_LOAD_TARGET_XXX values in your
* `load_flags'. They can't be ORed.
*
* If @FT_LOAD_RENDER is also set, the glyph is rendered in the
* corresponding mode (i.e., the mode which matches the used algorithm
* best). An exeption is FT_LOAD_TARGET_MONO since it implies
* @FT_LOAD_MONOCHROME.
*
* You can use a hinting algorithm that doesn't correspond to the same
* rendering mode. As an example, it is possible to use the `light'
* hinting algorithm and have the results rendered in horizontal LCD
* pixel mode, with code like
*
* {
* FT_Load_Glyph( face, glyph_index,
* load_flags | FT_LOAD_TARGET_LIGHT );
*
* FT_Render_Glyph( face->glyph, FT_RENDER_MODE_LCD );
* }

/* The FreeType~2 interface to Unicode Ideographic Variation */
/* Sequences (IVS), using the SFNT cmap format~14. */
/* */
/* <Description> */
/* Many CJK characters have variant forms. They are a sort of grey */
/* area somewhere between being totally irrelevant and semantically */
/* distinct; for this reason, the Unicode consortium decided to */
/* introduce Ideographic Variation Sequences (IVS), consisting of a */
/* Unicode base character and one of 240 variant selectors */
/* (U+E0100-U+E01EF), instead of further extending the already huge */
/* code range for CJK characters. */
/* */
/* An IVS is registered and unique; for further details please refer */
/* to Unicode Technical Standard #37, the Ideographic Variation */
/* Database: */
/* */
/* http://www.unicode.org/reports/tr37/ */
/* */
/* To date (November 2012), the character with the most variants is */
/* U+9089, having 31 such IVS. */
/* */
/* Adobe and MS decided to support IVS with a new cmap subtable */
/* (format~14). It is an odd subtable because it is not a mapping of */
/* input code points to glyphs, but contains lists of all variants */
/* supported by the font. */
/* */
/* A variant may be either `default' or `non-default'. A default */
/* variant is the one you will get for that code point if you look it */
/* up in the standard Unicode cmap. A non-default variant is a */
/* different glyph. */

* @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;

*
* <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:
* An opaque pointer type that is used to identity face objects. The

*
* These pointers are typically used to point to a user-defined

*
* @note:
* Never use NULL as a valid @FTC_FaceID.
*
* Face IDs are passed by the client to the cache manager, which calls,
* when needed, the @FTC_Face_Requester to translate them into new
* @FT_Face objects.
*
* If the content of a given face ID changes at runtime, or if the value
* becomes invalid (e.g., when uninstalling a font), you should
* immediately call @FTC_Manager_RemoveFaceID before any other cache
* function.
*
* Failure to do so will result in incorrect behaviour or even
* memory leaks and crashes.

/* */
/* FT_ERROR_DEF( e, v, s ) :: */

* LCD Filtering
*
* @abstract:
* Reduce color fringes of LCD-optimized bitmaps.
*
* @description:
* The @FT_Library_SetLcdFilter API can be used to specify a low-pass
* filter which is then applied to LCD-optimized bitmaps generated
* through @FT_Render_Glyph. This is useful to reduce color fringes
* which would occur with unfiltered rendering.
*
* Note that no filter is active by default, and that this function is
* *not* implemented in default builds of the library. You need to
* #define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in your `ftoption.h' file
* in order to activate it.
*
* FreeType generates alpha coverage maps, which are linear by nature.
* For instance, the value 0x80 in bitmap representation means that
* (within numerical precision) 0x80/0xff fraction of that pixel is
* covered by the glyph's outline. The blending function for placing
* text over a background is
*
* {
* dst = alpha * src + (1 - alpha) * dst ,
* }
*
* which is known as OVER. However, when calculating the output of the
* OVER operator, the source colors should first be transformed to a
* linear color space, then alpha blended in that space, and transformed
* back to the output color space.
*
* When linear light blending is used, the default FIR5 filtering
* weights (as given by FT_LCD_FILTER_DEFAULT) are no longer optimal, as
* they have been designed for black on white rendering while lacking
* gamma correction. To preserve color neutrality, weights for a FIR5
* filter should be chosen according to two free parameters `a' and `c',
* and the FIR weights should be
*
* {
* [a - c, a + c, 2 * a, a + c, a - c] .
* }
*
* This formula generates equal weights for all the color primaries
* across the filter kernel, which makes it colorless. One suggested
* set of weights is
*
* {
* [0x10, 0x50, 0x60, 0x50, 0x10] ,
* }
*
* where `a' has value 0x30 and `b' value 0x20. The weights in filter
* may have a sum larger than 0x100, which increases coloration slightly
* but also improves contrast.

*
* @description:
* Open a new stream to parse LZW-compressed font files. This is

* 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.

* @property:
* interpreter-version
*
* @description:
* Currently, two versions are available which represent the bytecode
* interpreter with and without subpixel hinting support,
* 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. The
* 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) font-specific
* tweaks.
*
* 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'.
*
* The following example code demonstrates how to activate subpixel
* hinting (omitting the error handling).
*
* {
* FT_Library library;
* FT_Face face;
* FT_UInt interpreter_version = TT_INTERPRETER_VERSION_38;

* "interpreter-version",

* }
*
* @note:
* This property can be used with @FT_Property_Get also.

*
* @enum:
* TT_INTERPRETER_VERSION_XXX
*
* @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).
*
* @note:
* This property controls the behaviour of the bytecode interpreter

* get rasterized! In particular, it does not control subpixel color
* filtering.

* encodings (except for cp1361) can be found at ftp://ftp.unicode.org
* 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
*
* http://www.microsoft.com/globaldev/reference/cphome.mspx,
*
* 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).
*

* 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

*
* FT_WinFNT_ID_CP950 ::
* A superset of traditional Chinese Big~5 ETen (with different

* 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 ::

/* */
/* An automatic hinter might compute two kinds of data for a given face: */
/* */
/* - global hints: Usually some metrics that describe global properties */
/* of the face. It is computed by scanning more or less */
/* aggressively the glyphs in the face, and thus can be */
/* very slow to compute (even if the size of global */
/* hints is really small). */
/* */
/* - glyph hints: These describe some important features of the glyph */
/* outline, as well as how to align them. They are */
/* generally much faster to compute than global hints. */
/* */
/* The current FreeType auto-hinter does a pretty good job while */
/* performing fast computations for both global and glyph hints. */
/* However, we might be interested in introducing more complex and */
/* powerful algorithms in the future, like the one described in the John */
/* D. Hobby paper, which unfortunately requires a lot more horsepower. */
/* */
/* Because a sufficiently sophisticated font management system would */
/* typically implement an LRU cache of opened face objects to reduce */
/* memory usage, it is a good idea to be able to avoid recomputing */
/* global hints every time the same face is re-opened. */
/* */
/* We thus provide the ability to cache global hints outside of the face */
/* object, in order to speed up font re-opening time. Of course, this */
/* feature is purely optional, so most client programs won't even notice */
/* it. */
/* */
/* I initially thought that it would be a good idea to cache the glyph */
/* hints too. However, my general idea now is that if you really need */
/* to cache these too, you are simply in need of a new font format, */
/* where all this information could be stored within the font file and */
/* decoded on the fly. */

* This is a handle to an opaque structure used to record glyph hints

*
* The methods used to operate on this object are defined by the
* @T1_Hints_FuncsRec structure. Recording glyph hints is normally
* achieved through the following scheme:
*
* - Open a new hint recording session by calling the `open' method.
* This rewinds the recorder and prepare it for new input.
*
* - For each hint found in the glyph charstring, call the corresponding
* method (`stem', `stem3', or `reset'). Note that these functions do
* not return an error code.
*
* - Close the recording session by calling the `close' method. It
* returns an error code if the hints were invalid or something
* strange happened (e.g., memory shortage).
*
* The hints accumulated in the object can later be used by the
* PostScript hinter.

*
* @description:
* Retrieve the value for the supplied key from a PostScript font.
*
* @input:
* face ::
* PostScript face handle.
*
* key ::
* An enumeration value representing the dictionary key to retrieve.
*
* idx ::
* For array values, this specifies the index to be returned.
*
* value ::
* A pointer to memory into which to write the value.
*
* valen_len ::
* The size, in bytes, of the memory supplied for the value.
*
* @output:
* value ::
* The value matching the above key, if it exists.
*
* @return:
* The amount of memory (in bytes) required to hold the requested
* value (if it exists, -1 otherwise).
*
* @note:
* The values returned are not pointers into the internal structures of
* the face, but are `fresh' copies, so that the memory containing them
* belongs to the calling application. This also enforces the
* `read-only' nature of these values, i.e., this function cannot be
* used to manipulate the face.
*
* `value' is a void pointer because the values returned can be of
* various types.
*
* If either `value' is NULL or `value_len' is too small, just the
* required memory size for the requested entry is returned.
*
* The `idx' parameter is used, not only to retrieve elements of, for
* example, the FontMatrix or FontBBox, but also to retrieve name keys
* from the CharStrings dictionary, and the charstrings themselves. It
* is ignored for atomic values.
*
* PS_DICT_BLUE_SCALE returns a value that is scaled up by 1000. To
* get the value as in the font stream, you need to divide by
* 65536000.0 (to remove the FT_Fixed scale, and the x1000 scale).
*
* IMPORTANT: Only key/value pairs read by the FreeType interpreter can
* be retrieved. So, for example, PostScript procedures such as NP,
* ND, and RD are not available. Arbitrary keys are, obviously, not be
* available either.
*
* If the font's format is not PostScript-based, this function returns
* the `FT_Err_Invalid_Argument' error code.
