/**************************************************************************

* @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 );

* for details on improving inter-glyph distances while rendering.

* @property:

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

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

*
* {
* stem width <= 0.5px: darkening amount = 0.4px
* stem width = 1px: darkening amount = 0.275px
* stem width = 1.667px: darkening amount = 0.275px
* stem width >= 2.333px: darkening amount = 0px
* }
*
* and piecewise linear in-between. At configuration time, these four
* control points can be set with the macro
* `CFF_CONFIG_OPTION_DARKENING_PARAMETERS'. At runtime, the control
* points can be changed using the `darkening-parameters' property, as
* the following example demonstrates.
*
* {
* FT_Library library;
* FT_Int darken_params[8] = { 500, 300, // x1, y1
* 1000, 200, // x2, y2

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

/* The header file `fterrors.h' (which is automatically included by */

/* */
/* *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&nbsp;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&nbsp;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. */

*
* @title:
* LCD Filtering
*
* @abstract:
* Reduce color fringes of subpixel-rendered bitmaps.
*
* @description:
* Subpixel rendering exploits the color-striped structure of LCD
* pixels, increasing the available resolution in the direction of the
* stripe (usually horizontal RGB) by a factor of~3. Since these
* subpixels are color pixels, using them unfiltered creates severe
* color fringes. Use the @FT_Library_SetLcdFilter API to specify a
* low-pass filter, which is then applied to subpixel-rendered bitmaps
* generated through @FT_Render_Glyph. The filter sacrifices some of
* the higher resolution to reduce color fringes, making the glyph image
* slightly blurrier. Positional improvements will remain.
*
* 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.
*
* A filter should have two properties:
*
* 1) It should be normalized, meaning the sum of the 5~components
* should be 256 (0x100). It is possible to go above or under this
* target sum, however: going under means tossing out contrast, going
* over means invoking clamping and thereby non-linearities that
* increase contrast somewhat at the expense of greater distortion
* and color-fringing. Contrast is better enhanced through stem
* darkening.
*
* 2) It should be color-balanced, meaning a filter `{~a, b, c, b, a~}'
* where a~+ b~=~c. It distributes the computed coverage for one
* subpixel to all subpixels equally, sacrificing some won resolution
* but drastically reducing color-fringing. Positioning improvements
* remain! Note that color-fringing can only really be minimized
* when using a color-balanced filter and alpha-blending the glyph
* onto a surface in linear space; see @FT_Render_Glyph.
*
* Regarding the form, a filter can be a `boxy' filter or a `beveled'
* filter. Boxy filters are sharper but are less forgiving of non-ideal
* gamma curves of a screen (viewing angles!), beveled filters are
* fuzzier but more tolerant.
*
* Examples:
*
* - [0x10 0x40 0x70 0x40 0x10] is beveled and neither balanced nor
* normalized.
*
* - [0x1A 0x33 0x4D 0x33 0x1A] is beveled and balanced but not
* normalized.
*
* - [0x19 0x33 0x66 0x4c 0x19] is beveled and normalized but not
* balanced.
*
* - [0x00 0x4c 0x66 0x4c 0x00] is boxily beveled and normalized but not
* balanced.
*
* - [0x00 0x55 0x56 0x55 0x00] is boxy, normalized, and almost
* balanced.
*
* - [0x08 0x4D 0x56 0x4D 0x08] is beveled, normalized and, almost
* balanced.
*
* It is important to understand that linear alpha blending and gamma
* correction is critical for correctly rendering glyphs onto surfaces
* without artifacts and even more critical when subpixel rendering is
* involved.
*
* Each of the 3~alpha values (subpixels) is independently used to blend
* one color channel. That is, red alpha blends the red channel of the
* text color with the red channel of the background pixel. The
* distribution of density values by the color-balanced filter assumes
* alpha blending is done in linear space; only then color artifacts
* cancel out.

/****************************************************************************
*
* @enum:
* FT_LcdFilter
*
* @description:
* A list of values to identify various types of LCD filters.
*
* @values:
* FT_LCD_FILTER_NONE ::
* Do not perform filtering. When used with subpixel rendering, this
* results in sometimes severe color fringes.
*
* FT_LCD_FILTER_DEFAULT ::
* The default filter reduces color fringes considerably, at the cost
* of a slight blurriness in the output.
*
* It is a beveled, normalized, and color-balanced five-tap filter
* that is more forgiving to screens with non-ideal gamma curves and
* viewing angles. Note that while color-fringing is reduced, it can
* only be minimized by using linear alpha blending and gamma
* correction to render glyphs onto surfaces.
*
* FT_LCD_FILTER_LIGHT ::
* The light filter is a variant that is sharper at the cost of
* slightly more color fringes than the default one.
*
* It is a boxy, normalized, and color-balanced three-tap filter that
* is less forgiving to screens with non-ideal gamma curves and
* viewing angles. This filter works best when the rendering system
* uses linear alpha blending and gamma correction to render glyphs
* onto surfaces.
*
* FT_LCD_FILTER_LEGACY ::
* This filter corresponds to the original libXft color filter. It
* provides high contrast output but can exhibit really bad color
* fringes if glyphs are not extremely well hinted to the pixel grid.
* In other words, it only works well if the TrueType bytecode
* interpreter is enabled *and* high-quality hinted fonts are used.
*
* This filter is only provided for comparison purposes, and might be
* disabled or stay unsupported in the future.
*
* FT_LCD_FILTER_LEGACY1 ::
* For historical reasons, the FontConfig library returns a different
* enumeration value for legacy LCD filtering. To make code work that
* (incorrectly) forwards FontConfig's enumeration value to
* @FT_Library_SetLcdFilter without proper mapping, it is thus easiest
* to have another enumeration value, which is completely equal to
* `FT_LCD_FILTER_LEGACY'.

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

/**************************************************************************
*
* @property:
* interpreter-version
*
* @description:
* Currently, two versions are available, representing 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 (except if `native
* ClearType' is selected by the font). 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;
*
*
* FT_Init_FreeType( &library );
*
* FT_Property_Set( library, "truetype",
* "interpreter-version",
* &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
* and thus how outlines get hinted. It does *not* control how glyph
* get rasterized! In particular, it does not control subpixel color
* filtering.
*
* If FreeType has not been compiled with configuration option
* FT_CONFIG_OPTION_SUBPIXEL_HINTING, selecting version~38 causes an
* `FT_Err_Unimplemented_Feature' error.
*
* Depending on the graphics framework, Microsoft uses different
* bytecode and rendering engines. As a consequence, the version
* numbers returned by a call to the `GETINFO' bytecode instruction are
* more convoluted than desired.
*
* Here are two tables that try to shed some light on the possible
* values for the MS rasterizer engine, together with the additional
* features introduced by it.
*
* {
* GETINFO framework version feature
* -------------------------------------------------------------------
* 3 GDI (Win 3.1), v1.0 16-bit, first version
* TrueImage
* 33 GDI (Win NT 3.1), v1.5 32-bit
* HP Laserjet
* 34 GDI (Win 95) v1.6 font smoothing,
* new SCANTYPE opcode
* 35 GDI (Win 98/2000) v1.7 (UN)SCALED_COMPONENT_OFFSET
* bits in composite glyphs
* 36 MGDI (Win CE 2) v1.6+ classic ClearType
* 37 GDI (XP and later), v1.8 ClearType
* GDI+ old (before Vista)
* 38 GDI+ old (Vista, Win 7), v1.9 subpixel ClearType,
* WPF Y-direction ClearType,
* additional error checking
* 39 DWrite (before Win 8) v2.0 subpixel ClearType flags
* in GETINFO opcode,
* bug fixes
* 40 GDI+ (after Win 7), v2.1 Y-direction ClearType flag
* DWrite (Win 8) in GETINFO opcode,
* Gray ClearType
* }
*
* The `version' field gives a rough orientation only, since some
* applications provided certain features much earlier (as an example,
* Microsoft Reader used subpixel and Y-direction ClearType already in
* Windows 2000). Similarly, updates to a given framework might include
* improved hinting support.
*
* {
* version sampling rendering comment
* x y x y
* --------------------------------------------------------------
* v1.0 normal normal B/W B/W bi-level
* v1.6 high high gray gray grayscale
* v1.8 high normal color-filter B/W (GDI) ClearType
* v1.9 high high color-filter gray Color ClearType
* v2.1 high normal gray B/W Gray ClearType
* v2.1 high high gray gray Gray ClearType
* }
*
* Color and Gray ClearType are the two available variants of
* `Y-direction ClearType', meaning grayscale rasterization along the
* Y-direction; the name used in the TrueType specification for this
* feature is `symmetric smoothing'. `Classic ClearType' is the
* original algorithm used before introducing a modified version in
* Win~XP. Another name for v1.6's grayscale rendering is `font
* smoothing', and `Color ClearType' is sometimes also called `DWrite
* ClearType'. To differentiate between today's Color ClearType and the
* earlier ClearType variant with B/W rendering along the vertical axis,
* the latter is sometimes called `GDI ClearType'.
*
* `Normal' and `high' sampling describe the (virtual) resolution to
* access the rasterized outline after the hinting process. `Normal'
* means 1 sample per grid line (i.e., B/W). In the current Microsoft
* implementation, `high' means an extra virtual resolution of 16x16 (or
* 16x1) grid lines per pixel for bytecode instructions like `MIRP'.
* After hinting, these 16 grid lines are mapped to 6x5 (or 6x1) grid
* lines for color filtering if Color ClearType is activated.
*
* Note that `Gray ClearType' is essentially the same as v1.6's
* grayscale rendering. However, the GETINFO instruction handles it
* differently: v1.6 returns bit~12 (hinting for grayscale), while v2.1
* returns bits~13 (hinting for ClearType), 18 (symmetrical smoothing),
* and~19 (Gray ClearType). Also, this mode respects bits 2 and~3 for
* the version~1 gasp table exclusively (like Color ClearType), while
* v1.6 only respects the values of version~0 (bits 0 and~1).
*
* FreeType doesn't provide all capabilities of the most recent
* ClearType incarnation, thus we identify our subpixel support as
* version~38.

* FT_WinFNT_ID_XXX
*
* @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 ::
* Korean (Johab).

* @function:
* FT_Get_PS_Font_Value
*
* @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.

* @description:
* While FreeType's auto-hinter doesn't expose API functions by itself,

/**************************************************************************
*
* @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 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.
*

*
* 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.

* @property:
* no-stem-darkening[autofit]
*
* @description:
* *Experimental* *only,* *requires* *linear* *alpha* *blending* *and*
* *gamma* *correction*
*
* Stem darkening emboldens glyphs at smaller sizes to make them more
* readable on common low-DPI screens when using linear alpha blending
* and gamma correction, see @FT_Render_Glyph. When not using linear
* alpha blending and gamma correction, glyphs will appear heavy and
* fuzzy!
*
* Gamma correction essentially lightens fonts since shades of grey are
* shifted to higher pixel values (=~higher brightness) to match the
* original intention to the reality of our screens. The side-effect is
* that glyphs `thin out'. Mac OS~X and Adobe's proprietary font
* rendering library implement a counter-measure: stem darkening at
* smaller sizes where shades of gray dominate. By emboldening a glyph
* slightly in relation to its pixel size, individual pixels get higher
* coverage of filled-in outlines and are therefore `blacker'. This
* counteracts the `thinning out' of glyphs, making text remain readable
* at smaller sizes. All glyphs that pass through the auto-hinter will
* be emboldened unless this property is set to TRUE.
*
* See the description of the CFF driver for algorithmic details. Total
* consistency with the CFF driver is currently not achieved because the
* emboldening method differs and glyphs must be scaled down on the
* Y-axis to keep outline points inside their precomputed blue zones.
* The smaller the size (especially 9ppem and down), the higher the loss
* of emboldening versus the CFF driver.

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

* Thanks to Adobe, which contributed a new hinting (and parsing)
* engine, an application can select between `freetype' and `adobe' if
* compiled with CFF_CONFIG_OPTION_OLD_ENGINE. If this configuration
* macro isn't defined, `hinting-engine' does nothing.
*
* The default engine is `freetype' if CFF_CONFIG_OPTION_OLD_ENGINE is
* defined, and `adobe' otherwise.
*
* The following example code demonstrates how to select Adobe's hinting
* engine (omitting the error handling).

/**************************************************************************
*
* @property:
* darkening-parameters[cff]
*
* @description:
* By default, the Adobe CFF engine darkens stems as follows (if the
* `no-stem-darkening' property isn't set):
*
* {
* stem width <= 0.5px: darkening amount = 0.4px
* stem width = 1px: darkening amount = 0.275px
* stem width = 1.667px: darkening amount = 0.275px
* stem width >= 2.333px: darkening amount = 0px
* }
*
* and piecewise linear in-between. At configuration time, these four
* control points can be set with the macro
* `CFF_CONFIG_OPTION_DARKENING_PARAMETERS'. At runtime, the control
* points can be changed using the `darkening-parameters' property, as
* the following example demonstrates.
*
* {
* FT_Library library;
* FT_Int darken_params[8] = { 500, 300, // x1, y1
* 1000, 200, // x2, y2
* 1500, 100, // x3, y3
* 2000, 0 }; // x4, y4
*
*
* FT_Init_FreeType( &library );
*
* FT_Property_Set( library, "cff",
* "darkening-parameters", darken_params );
* }
*
* The x~values give the stem width, and the y~values the darkening
* amount. The unit is 1000th of pixels. All coordinate values must be
* positive; the x~values must be monotonically increasing; the
* y~values must be monotonically decreasing and smaller than or
* equal to 500 (corresponding to half a pixel); the slope of each
* linear piece must be shallower than -1 (e.g., -.4).
*
* @note:
* This property can be used with @FT_Property_Get also.

* @description:
* Subpixel rendering exploits the color-striped structure of LCD

* color fringes. Use the @FT_Library_SetLcdFilter API to specify a

* generated through @FT_Render_Glyph. The filter sacrifices some of
* the higher resolution to reduce color fringes, making the glyph image
* slightly blurrier. Positional improvements will remain.
*
* 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.
*
* A filter should have two properties:
*
* 1) It should be normalized, meaning the sum of the 5~components
* should be 256 (0x100). It is possible to go above or under this
* target sum, however: going under means tossing out contrast, going
* over means invoking clamping and thereby non-linearities that
* increase contrast somewhat at the expense of greater distortion
* and color-fringing. Contrast is better enhanced through stem
* darkening.
*
* 2) It should be color-balanced, meaning a filter `{~a, b, c, b, a~}'
* where a~+ b~=~c. It distributes the computed coverage for one
* subpixel to all subpixels equally, sacrificing some won resolution
* but drastically reducing color-fringing. Positioning improvements
* remain! Note that color-fringing can only really be minimized
* when using a color-balanced filter and alpha-blending the glyph
* onto a surface in linear space; see @FT_Render_Glyph.
*
* Regarding the form, a filter can be a `boxy' filter or a `beveled'
* filter. Boxy filters are sharper but are less forgiving of non-ideal
* gamma curves of a screen (viewing angles!), beveled filters are
* fuzzier but more tolerant.
*
* Examples:
*
* - [0x10 0x40 0x70 0x40 0x10] is beveled and neither balanced nor
* normalized.
*
* - [0x1A 0x33 0x4D 0x33 0x1A] is beveled and balanced but not
* normalized.
*
* - [0x19 0x33 0x66 0x4c 0x19] is beveled and normalized but not
* balanced.
*
* - [0x00 0x4c 0x66 0x4c 0x00] is boxily beveled and normalized but not
* balanced.
*
* - [0x00 0x55 0x56 0x55 0x00] is boxy, normalized, and almost
* balanced.
*
* - [0x08 0x4D 0x56 0x4D 0x08] is beveled, normalized and, almost
* balanced.
*
* It is important to understand that linear alpha blending and gamma
* correction is critical for correctly rendering glyphs onto surfaces
* without artifacts and even more critical when subpixel rendering is
* involved.
*
* Each of the 3~alpha values (subpixels) is independently used to blend
* one color channel. That is, red alpha blends the red channel of the
* text color with the red channel of the background pixel. The
* distribution of density values by the color-balanced filter assumes
* alpha blending is done in linear space; only then color artifacts
* cancel out.

* @enum:
* FT_LcdFilter
*
* @description:
* A list of values to identify various types of LCD filters.
*
* @values:
* FT_LCD_FILTER_NONE ::
* Do not perform filtering. When used with subpixel rendering, this
* results in sometimes severe color fringes.
*
* FT_LCD_FILTER_DEFAULT ::
* The default filter reduces color fringes considerably, at the cost
* of a slight blurriness in the output.
*
* It is a beveled, normalized, and color-balanced five-tap filter
* that is more forgiving to screens with non-ideal gamma curves and
* viewing angles. Note that while color-fringing is reduced, it can
* only be minimized by using linear alpha blending and gamma
* correction to render glyphs onto surfaces.
*
* FT_LCD_FILTER_LIGHT ::
* The light filter is a variant that is sharper at the cost of
* slightly more color fringes than the default one.
*
* It is a boxy, normalized, and color-balanced three-tap filter that
* is less forgiving to screens with non-ideal gamma curves and
* viewing angles. This filter works best when the rendering system
* uses linear alpha blending and gamma correction to render glyphs
* onto surfaces.
*
* FT_LCD_FILTER_LEGACY ::
* This filter corresponds to the original libXft color filter. It
* provides high contrast output but can exhibit really bad color
* fringes if glyphs are not extremely well hinted to the pixel grid.
* In other words, it only works well if the TrueType bytecode
* interpreter is enabled *and* high-quality hinted fonts are used.
*
* This filter is only provided for comparison purposes, and might be
* disabled or stay unsupported in the future.
*
* FT_LCD_FILTER_LEGACY1 ::
* For historical reasons, the FontConfig library returns a different
* enumeration value for legacy LCD filtering. To make code work that
* (incorrectly) forwards FontConfig's enumeration value to
* @FT_Library_SetLcdFilter without proper mapping, it is thus easiest
* to have another enumeration value, which is completely equal to
* `FT_LCD_FILTER_LEGACY'.
*
* @since:
* 2.3.0 (`FT_LCD_FILTER_LEGACY1' since 2.6.2)

* FT_Library_SetLcdFilter
*
* @description:
* This function is used to apply color filtering to LCD decimated

* @FT_RENDER_MODE_LCD or @FT_RENDER_MODE_LCD_V.
*
* @input:
* library ::
* A handle to the target library instance.
*
* filter ::
* The filter type.
*
* You can use @FT_LCD_FILTER_NONE here to disable this feature, or
* @FT_LCD_FILTER_DEFAULT to use a default filter that should work
* well on most LCD screens.
*
* @return:
* FreeType error code. 0~means success.
*
* @note:
* This feature is always disabled by default. Clients must make an
* explicit call to this function with a `filter' value other than
* @FT_LCD_FILTER_NONE in order to enable it.
*
* Due to *PATENTS* covering subpixel rendering, this function doesn't
* do anything except returning `FT_Err_Unimplemented_Feature' if the
* configuration macro FT_CONFIG_OPTION_SUBPIXEL_RENDERING is not
* defined in your build of the library, which should correspond to all
* default builds of FreeType.
*
* The filter affects glyph bitmaps rendered through @FT_Render_Glyph,
* @FT_Outline_Get_Bitmap, @FT_Load_Glyph, and @FT_Load_Char.
*
* It does _not_ affect the output of @FT_Outline_Render and
* @FT_Outline_Get_Bitmap.
*
* If this feature is activated, the dimensions of LCD glyph bitmaps are
* either larger or taller than the dimensions of the corresponding
* outline with regards to the pixel grid. For example, for
* @FT_RENDER_MODE_LCD, the filter adds up to 3~pixels to the left, and
* up to 3~pixels to the right.
*
* The bitmap offset values are adjusted correctly, so clients shouldn't
* need to modify their layout and glyph positioning code when enabling
* the filter.

* FT_STROKER_LINEJOIN_MITER_FIXED ::
* Used to render mitered line joins, with fixed bevels if the
* miter limit is exceeded. The outer edges of the strokes
* for the two segments are extended until they meet at an
* angle. If the segments meet at too sharp an angle (such
* that the miter would extend from the intersection of the

* limit value and the border radius), then a bevel join (see

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

/**************************************************************************
*
* @property:
* interpreter-version
*
* @description:
* Currently, two versions are available, representing 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 (except if `native
* ClearType' is selected by the font). 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;
*
*
* FT_Init_FreeType( &library );
*
* FT_Property_Set( library, "truetype",
* "interpreter-version",
* &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
* and thus how outlines get hinted. It does *not* control how glyph
* get rasterized! In particular, it does not control subpixel color
* filtering.
*
* If FreeType has not been compiled with configuration option
* FT_CONFIG_OPTION_SUBPIXEL_HINTING, selecting version~38 causes an
* `FT_Err_Unimplemented_Feature' error.
*
* Depending on the graphics framework, Microsoft uses different
* bytecode and rendering engines. As a consequence, the version
* numbers returned by a call to the `GETINFO' bytecode instruction are
* more convoluted than desired.
*
* Here are two tables that try to shed some light on the possible
* values for the MS rasterizer engine, together with the additional
* features introduced by it.
*
* {
* GETINFO framework version feature
* -------------------------------------------------------------------
* 3 GDI (Win 3.1), v1.0 16-bit, first version
* TrueImage
* 33 GDI (Win NT 3.1), v1.5 32-bit
* HP Laserjet
* 34 GDI (Win 95) v1.6 font smoothing,
* new SCANTYPE opcode
* 35 GDI (Win 98/2000) v1.7 (UN)SCALED_COMPONENT_OFFSET
* bits in composite glyphs
* 36 MGDI (Win CE 2) v1.6+ classic ClearType
* 37 GDI (XP and later), v1.8 ClearType
* GDI+ old (before Vista)
* 38 GDI+ old (Vista, Win 7), v1.9 subpixel ClearType,
* WPF Y-direction ClearType,
* additional error checking
* 39 DWrite (before Win 8) v2.0 subpixel ClearType flags
* in GETINFO opcode,
* bug fixes
* 40 GDI+ (after Win 7), v2.1 Y-direction ClearType flag
* DWrite (Win 8) in GETINFO opcode,
* Gray ClearType
* }
*
* The `version' field gives a rough orientation only, since some
* applications provided certain features much earlier (as an example,
* Microsoft Reader used subpixel and Y-direction ClearType already in
* Windows 2000). Similarly, updates to a given framework might include
* improved hinting support.
*
* {
* version sampling rendering comment
* x y x y
* --------------------------------------------------------------
* v1.0 normal normal B/W B/W bi-level
* v1.6 high high gray gray grayscale
* v1.8 high normal color-filter B/W (GDI) ClearType
* v1.9 high high color-filter gray Color ClearType
* v2.1 high normal gray B/W Gray ClearType
* v2.1 high high gray gray Gray ClearType
* }
*
* Color and Gray ClearType are the two available variants of
* `Y-direction ClearType', meaning grayscale rasterization along the
* Y-direction; the name used in the TrueType specification for this
* feature is `symmetric smoothing'. `Classic ClearType' is the
* original algorithm used before introducing a modified version in
* Win~XP. Another name for v1.6's grayscale rendering is `font
* smoothing', and `Color ClearType' is sometimes also called `DWrite
* ClearType'. To differentiate between today's Color ClearType and the
* earlier ClearType variant with B/W rendering along the vertical axis,
* the latter is sometimes called `GDI ClearType'.
*
* `Normal' and `high' sampling describe the (virtual) resolution to
* access the rasterized outline after the hinting process. `Normal'
* means 1 sample per grid line (i.e., B/W). In the current Microsoft
* implementation, `high' means an extra virtual resolution of 16x16 (or
* 16x1) grid lines per pixel for bytecode instructions like `MIRP'.
* After hinting, these 16 grid lines are mapped to 6x5 (or 6x1) grid
* lines for color filtering if Color ClearType is activated.
*
* Note that `Gray ClearType' is essentially the same as v1.6's
* grayscale rendering. However, the GETINFO instruction handles it
* differently: v1.6 returns bit~12 (hinting for grayscale), while v2.1
* returns bits~13 (hinting for ClearType), 18 (symmetrical smoothing),
* and~19 (Gray ClearType). Also, this mode respects bits 2 and~3 for
* the version~1 gasp table exclusively (like Color ClearType), while
* v1.6 only respects the values of version~0 (bits 0 and~1).
*
* FreeType doesn't provide all capabilities of the most recent
* ClearType incarnation, thus we identify our subpixel support as
* version~38.

* @enum:
* FT_WinFNT_ID_XXX
*
* @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 ::
* Korean (Johab).

*
* @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.

/**************************************************************************

* @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 );

*
* prop.face = face;
*

* Warping only works in `light' auto-hinting mode. The idea of the

* its segments are aligned (more or less) to the grid. To find out a
* glyph's optimal scaling and shifting value, various parameter

* 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.

* @property:
* no-stem-darkening[autofit]
*
* @description:
* *Experimental* *only,* *requires* *linear* *alpha* *blending* *and*
* *gamma* *correction*
*
* Stem darkening emboldens glyphs at smaller sizes to make them more
* readable on common low-DPI screens when using linear alpha blending
* and gamma correction, see @FT_Render_Glyph. When not using linear
* alpha blending and gamma correction, glyphs will appear heavy and
* fuzzy!
*
* Gamma correction essentially lightens fonts since shades of grey are
* shifted to higher pixel values (=~higher brightness) to match the
* original intention to the reality of our screens. The side-effect is
* that glyphs `thin out'. Mac OS~X and Adobe's proprietary font
* rendering library implement a counter-measure: stem darkening at
* smaller sizes where shades of gray dominate. By emboldening a glyph
* slightly in relation to its pixel size, individual pixels get higher
* coverage of filled-in outlines and are therefore `blacker'. This
* counteracts the `thinning out' of glyphs, making text remain readable
* at smaller sizes. All glyphs that pass through the auto-hinter will
* be emboldened unless this property is set to TRUE.
*
* See the description of the CFF driver for algorithmic details. Total
* consistency with the CFF driver is currently not achieved because the
* emboldening method differs and glyphs must be scaled down on the
* Y-axis to keep outline points inside their precomputed blue zones.
* The smaller the size (especially 9ppem and down), the higher the loss
* of emboldening versus the CFF driver.

* @function:
* FT_Stream_OpenBzip2
*
* @description:
* Open a new stream to parse bzip2-compressed font files. This is
* mainly used to support the compressed `*.pcf.bz2' fonts that come
* with XFree86.
*
* @input:
* stream ::
* The target embedding stream.
*
* source ::
* The source stream.
*
* @return:
* FreeType error code. 0~means success.
*
* @note:
* The source stream must be opened _before_ calling this function.
*
* Calling the internal function `FT_Stream_Close' on the new stream will
* *not* call `FT_Stream_Close' on the source stream. None of the stream
* objects will be released to the heap.
*
* The stream implementation is very basic and resets the decompression
* process each time seeking backwards is needed within the stream.
*
* In certain builds of the library, bzip2 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 bzip2 compressed 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 bzip2 support.
