+   * @property:
+   *   glyph-to-script-map
+   *
+   * @description:
+   *   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).
+   *

+   *   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:
+   *   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;
+   *
+   *
+   *     FT_Init_FreeType( &library );
+   *
+   *     FT_Property_Set( library, "truetype",
+   *                               "interpreter-version",
+   *                               &interpreter_version );
+   *   }
+   *
+   * @note:
+   *   This property can be used with @FT_Property_Get also.

+   *
+   * @description:

+   *   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

+   *  FTC_GCache is an _abstract_ cache object optimized to store glyph

+   *   - It manages FTC_GNode objects. Each one of them can hold one or more
+   *     glyph `items'.  Item types are not specified in the FTC_GCache but
+   *     in classes that extend it.
+   *
+   *   - Glyph attributes, like face ID, character size, render mode, etc.,
+   *     can be grouped into abstract `glyph families'.  This avoids storing
+   *     the attributes within the FTC_GCache, since it is likely that many
+   *     FTC_GNodes will belong to the same family in typical uses.

+   *   - Each FTC_GNode is thus an FTC_Node with two additional fields:
+   *
+   *       * gindex: A glyph index, or the first index in a glyph range.
+   *       * family: A pointer to a glyph `family'.
+   *
+   *   - Family types are not fully specific in the FTC_Family type, but
+   *     by classes that extend it.
+   *
+   *  Note that both FTC_ImageCache and FTC_SBitCache extend FTC_GCache.
+   *  They share an FTC_Family sub-class called FTC_BasicFamily which is
+   *  used to store the following data: face ID, pixel/point sizes, load
+   *  flags.  For more details see the file `src/cache/ftcbasic.c'.
+   *
+   *  Client applications can extend FTC_GNode with their own FTC_GNode
+   *  and FTC_Family sub-classes to implement more complex caches (e.g.,
+   *  handling automatic synthesis, like obliquing & emboldening, colored
+   *  glyphs, etc.).
+   *
+   *  See also the FTC_ICache & FTC_SCache classes in `ftcimage.h' and
+   *  `ftcsbits.h', which both extend FTC_GCache with additional
+   *  optimizations.
+   *
+   *  A typical FTC_GCache implementation must provide at least the
+   *  following:
+   *
+   *  - FTC_GNode sub-class, e.g. MyNode, with relevant methods:
+   *        my_node_new            (must call FTC_GNode_Init)
+   *        my_node_free           (must call FTC_GNode_Done)
+   *        my_node_compare        (must call FTC_GNode_Compare)
+   *        my_node_remove_faceid  (must call ftc_gnode_unselect in case
+   *                                of match)
+   *
+   *  - FTC_Family sub-class, e.g. MyFamily, with relevant methods:
+   *        my_family_compare
+   *        my_family_init
+   *        my_family_reset (optional)
+   *        my_family_done
+   *
+   *  - FTC_GQuery sub-class, e.g. MyQuery, to hold cache-specific query
+   *    data.
+   *
+   *  - Constant structures for a FTC_GNodeClass.
+   *
+   *  - MyCacheNew() can be implemented easily as a call to the convenience
+   *    function FTC_GCache_New.
+   *
+   *  - MyCacheLookup with a call to FTC_GCache_Lookup.  This function will
+   *    automatically:
+   *
+   *    - Search for the corresponding family in the cache, or create
+   *      a new one if necessary.  Put it in FTC_GQUERY(myquery).family
+   *
+   *    - Call FTC_Cache_Lookup.
+   *
+   *    If it returns NULL, you should create a new node, then call
+   *    ftc_cache_add as usual.

+       *  prevent it from being flushed within the loop.
+       *
+       *  When we exit the loop, we unlock the node, then check the `error'

+       *  completely flushed and that no usable memory was found to load
+       *  the bitmap.
+       *
+       *  We then prefer to return a value of 0 (i.e., NO MATCH).  This
+       *  ensures that the caller will try to allocate a new node.
+       *  This operation consequently _fail_ and the lookup function
+       *  returns the appropriate OOM error code.
+       *
+       *  Note that `buffer == NULL && width == 255' is a hack used to

+   * A poor-man error facility.
+   *
+   * This code being written in vanilla C, doesn't have the luxury of a
+   * language-supported exception mechanism such as the one available in
+   * Java.  Instead, we are stuck with using error codes that must be
+   * carefully managed and preserved.  However, it is convenient for us to
+   * model our error mechanism on a Java-like exception mechanism.
+   * When we assign an error code we are thus `throwing' an error.
+   *
+   * The perservation of an error code is done by coding convention.
+   * Upon a function call if the error code is anything other than
+   * `FT_Err_Ok', which is guaranteed to be zero, we
+   * will return without altering that error.  This will allow the
+   * error to propogate and be handled at the appropriate location in
+   * the code.
+   *
+   * This allows a style of code where the error code is initialized
+   * up front and a block of calls are made with the error code only
+   * being checked after the block.  If a new error occurs, the original
+   * error will be preserved and a functional no-op should result in any
+   * subsequent function that has an initial error code not equal to
+   * `FT_Err_Ok'.
+   *
+   * Errors are encoded by calling the `FT_THROW' macro.  For example,
+   *
+   * {
+   *   FT_Error  e;
+   *
+   *
+   *   ...
+   *   e = FT_THROW( Out_Of_Memory );
