   *
   * @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 outline glyph loaded, but keep it in font units.
   *
   *     This flag implies @FT_LOAD_NO_HINTING and @FT_LOAD_NO_BITMAP, and
   *     unsets @FT_LOAD_RENDER.
   *
   *   FT_LOAD_NO_HINTING ::
   *     Disable hinting.  This generally generates `blurrier' bitmap glyph
   *     when the glyph is 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.  _Don't_ use it as it is
   *     problematic currently.
   *
   *   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.
   *
   * @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.

   *
   * @enum:
   *   FT_LOAD_TARGET_XXX
   *
   * @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 );

   *   The @FT_Library_SetLcdFilter API can be used to specify a low-pass

   *   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

   *
   * @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.
   *
   *   FT_LCD_FILTER_LIGHT ::
   *     The light filter is a variant that produces less blurriness at the
   *     cost of slightly more color fringes than the default one.  It might
   *     be better, depending on taste, your monitor, or your personal vision.
   *
   *   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_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.

   *
   *
   *  Segments
   *
   *    `af_{cjk,latin,...}_hints_compute_segments' are the functions to
   *    find segments in an outline.  A segment is a series of consecutive
   *    points that are approximately aligned along a coordinate axis.  The
   *    analysis to do so is specific to a script.
   *
   *    A segment must have at least two points, except in the case of
   *    `fake' segments that are generated to hint metrics appropriately,
   *    and which consist of a single point.
   *
   *
   *  Edges
   *
   *    As soon as segments are defined, the auto-hinter groups them into
   *    edges.  An edge corresponds to a single position on the main
   *    dimension that collects one or more segments (allowing for a small
   *    threshold).
   *
   *    The auto-hinter first tries to grid fit edges, then to align
   *    segments on the edges unless it detects that they form a serif.
   *
   *    `af_{cjk,latin,...}_hints_compute_edges' are the functions to find
   *    edges; they are specific to a script.

   *
   *
   *  Stems
   *
   *    Segments need to be `linked' to other ones in order to detect stems.
   *    A stem is made of two segments that face each other in opposite
   *    directions and that are sufficiently close to each other.  Using
   *    vocabulary from the TrueType specification, stem segments form a
   *    `black distance'.
   *
   *    In the above ASCII drawing, the horizontal segments are BC, DE, and
   *    FG; the vertical segments are AB, CD, EF, and GH.
   *
   *    Each segment has at most one `best' candidate to form a black
   *    distance, or no candidate at all.  Notice that two distinct segments
   *    can have the same candidate, which frequently means a serif.
   *
   *    A stem is recognized by the following condition:
   *
   *      best segment_1 = segment_2 && best segment_2 = segment_1
   *
   *    The best candidate is stored in field `link' in structure
   *    `AF_Segment'.
   *
   *    Stems are detected by `af_{cjk,latin,...}_hint_edges'.
   *
   *    In the above ASCII drawing, the best candidate for both AB and CD is
   *    GH, while the best candidate for GH is AB.  Similarly, the best
   *    candidate for EF and GH is AB, while the best candidate for AB is
   *    GH.
   *
   *
   *  Serifs
   *
   *    On the opposite, a serif has
   *
   *      best segment_1 = segment_2 && best segment_2 != segment_1
   *
   *    where segment_1 corresponds to the serif segment (CD and EF in the
   *    above ASCII drawing).
   *
   *    The best candidate is stored in field `serif' in structure
   *    `AF_Segment' (and `link' is set to NULL).
   *
   *    Serifs are detected by `af_{cjk,latin,...}_hint_edges'.
   *
   *
   *  Touched points
   *
   *    A point is called `touched' if it has been processed somehow by the
   *    auto-hinter.  It basically means that it shouldn't be moved again
   *    (or moved only under certain constraints to preserve the already
   *    applied processing).
   *
   *
   *  Flat and round segments
   *
   *    Segments are `round' or `flat', depending on the series of points
   *    that define them.  A segment is round if the next and previous point
   *    of an extremum (which can be either a single point or sequence of
   *    points) are both conic or cubic control points.  Otherwise, a
   *    segment with an extremum is flat.
   *
   *
   *  Strong Points
   *
   *    Experience has shown that points which are not part of an edge need
   *    to be interpolated linearly between their two closest edges, even if
   *    these are not part of the contour of those particular points.
   *    Typical candidates for this are
   *
   *    - angle points (i.e., points where the `in' and `out' direction
   *      differ greatly)
   *
   *    - inflection points (i.e., where the `in' and `out' angles are the
   *      same, but the curvature changes sign)
   *
   *    `af_glyph_hints_align_strong_points' is the function which takes
   *    care of such situations; it is equivalent to the TrueType `IP'
   *    hinting instruction.
   *
   *
   *  Weak Points
   *
   *    Other points in the outline must be interpolated using the
   *    coordinates of their previous and next unfitted contour neighbours.
   *    These are called `weak points' and are touched by the function
   *    `af_glyph_hints_align_weak_points', equivalent to the TrueType `IUP'
   *    hinting instruction.  Typical candidates are control points and
   *    points on the contour without a major direction.
   *
   *    The major effect is to reduce possible distortion caused by
   *    alignment of edges and strong points, thus weak points are processed
   *    after strong points.

   *
   * @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.

  *   Load any font table into client memory.
  *
  * @input:
  *   face ::
  *     A handle to the source face.
  *
  *   tag ::
  *     The four-byte tag of the table to load.  Use the value~0 if you want
  *     to access the whole font file.  Otherwise, you can use one of the
  *     definitions found in the @FT_TRUETYPE_TAGS_H file, or forge a new
  *     one with @FT_MAKE_TAG.
  *
  *   offset ::
  *     The starting offset in the table (or file if tag == 0).
  *
  * @output:
  *   buffer ::
  *     The target buffer address.  The client must ensure that the memory
  *     array is big enough to hold the data.
  *
  * @inout:
  *   length ::
  *     If the `length' parameter is NULL, then try to load the whole table.
  *     Return an error code if it fails.
  *
  *     Else, if `*length' is~0, exit immediately while returning the
  *     table's (or file) full size in it.
  *
  *     Else the number of bytes to read from the table or file, from the
  *     starting offset.
  *
  * @return:
  *   FreeType error code.  0~means success.
  *
  * @note:
  *   If you need to determine the table's length you should first call this
  *   function with `*length' set to~0, as in the following example:
  *
  *     {
  *       FT_ULong  length = 0;
  *
  *
  *       error = FT_Load_Sfnt_Table( face, tag, 0, NULL, &length );

  *
  *       buffer = malloc( length );

   * The format of the table is as follows.
   *
   *   USHORT   version      `BDF ' table version number, should be 0x0001.
   *   USHORT   strikeCount  Number of strikes (bitmap sizes) in this table.

   *                         table.
   *
   * This is followed by an array of `strikeCount' descriptors, having the
   * following format.
   *
   *   USHORT   ppem         Vertical pixels per EM for this strike.

   *
   *   ULONG    item_name    Offset in string table to item name.
   *   USHORT   item_type    The item type.  Possible values are
   *                            0 => string (e.g., COMMENT)
   *                            1 => atom   (e.g., FONT or even SIZE)

   *   ULONG    item_value   For strings  => Offset into string table without
   *                                         the corresponding double quotes.
   *                         For atoms    => Offset into string table.

    Notes

    Mac suitcase files can (and often do!) contain multiple fonts.  To
    support this I use the face_index argument of FT_(Open|New)_Face()
    functions, and pretend the suitcase file is a collection.

    Warning: fbit and NFNT bitmap resources are not supported yet.  In old
    sfnt fonts, bitmap glyph data for each size is stored in each `NFNT'
    resources instead of the `bdat' table in the sfnt resource.  Therefore,
    face->num_fixed_sizes is set to 0, because bitmap data in `NFNT'
    resource is unavailable at present.

    The Mac FOND support works roughly like this:

    - Check whether the offered stream points to a Mac suitcase file.  This
      is done by checking the file type: it has to be 'FFIL' or 'tfil'.  The
      stream that gets passed to our init_face() routine is a stdio stream,
      which isn't usable for us, since the FOND resources live in the
      resource fork.  So we just grab the stream->pathname field.

    - Read the FOND resource into memory, then check whether there is a
      TrueType font and/or(!) a Type 1 font available.

    - If there is a Type 1 font available (as a separate `LWFN' file), read
      its data into memory, massage it slightly so it becomes PFB data, wrap
      it into a memory stream, load the Type 1 driver and delegate the rest
      of the work to it by calling FT_Open_Face().  (XXX TODO: after this
      has been done, the kerning data from the FOND resource should be
      appended to the face: On the Mac there are usually no AFM files
      available.  However, this is tricky since we need to map Mac char
      codes to ps glyph names to glyph ID's...)

    - If there is a TrueType font (an `sfnt' resource), read it into memory,
      wrap it into a memory stream, load the TrueType driver and delegate
      the rest of the work to it, by calling FT_Open_Face().

    - Some suitcase fonts (notably Onyx) might point the `LWFN' file to
      itself, even though it doesn't contains `POST' resources.  To handle
      this special case without opening the file an extra time, we just
      ignore errors from the `LWFN' and fallback to the `sfnt' if both are
      available.

   * <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.

   *   the cache manager to translate a given @FTC_FaceID into a new valid
   *   @FT_Face object, on demand.
   *
   * <Input>
   *   face_id ::
   *     The face ID to resolve.
   *
   *   library ::
   *     A handle to a FreeType library object.
   *
   *   req_data ::
   *     Application-provided request data (see note below).
   *
   * <Output>
   *   aface ::
   *     A new @FT_Face handle.
   *
   * <Return>
   *   FreeType error code.  0~means success.
   *
   * <Note>
   *   The third parameter `req_data' is the same as the one passed by the
   *   client when @FTC_Manager_New is called.
   *
   *   The face requester should not perform funny things on the returned
   *   face object, like creating a new @FT_Size for it, or setting a
   *   transformation through @FT_Set_Transform!

  /*
   *
   *  FTC_GCache is an _abstract_ cache object optimized to store glyph
   *  data.  It works as follows:
   *
   *   - 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.

       *
       *  Here, we want to load a small bitmap on-demand; we thus
       *  need to call the `ftc_snode_load' function which may return
       *  a non-zero error code only when we are out of memory (OOM).
       *
       *  The correct thing to do is to use @FTC_CACHE_TRYLOOP and
       *  @FTC_CACHE_TRYLOOP_END in order to implement a retry loop
       *  that is capable of flushing the cache incrementally when
       *  an OOM errors occur.
       *
       *  However, we need to `lock' the node before this operation to
       *  prevent it from being flushed within the loop.
       *
       *  When we exit the loop, we unlock the node, then check the `error'
       *  variable.  If it is non-zero, this means that the cache was
       *  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
       *  tag `unavailable' bitmaps in the array.  We should never try
       *  to load these.

   *
   * @values:
   *   FT_GASP_NO_TABLE ::
   *     This special value means that there is no GASP table in this face.
   *     It is up to the client to decide what to do.
   *
   *   FT_GASP_DO_GRIDFIT ::
   *     Grid-fitting and hinting should be performed at the specified ppem.
   *     This *really* means TrueType bytecode interpretation.  If this bit
   *     is not set, no hinting gets applied.
   *
   *   FT_GASP_DO_GRAY ::
   *     Anti-aliased rendering should be performed at the specified ppem.
   *     If not set, do monochrome rendering.
   *
   *   FT_GASP_SYMMETRIC_SMOOTHING ::
   *     If set, smoothing along multiple axes must be used with ClearType.
   *
   *   FT_GASP_SYMMETRIC_GRIDFIT ::
   *     Grid-fitting must be used with ClearType's symmetric smoothing.
   *
   * @note:
   *   The bit-flags `FT_GASP_DO_GRIDFIT' and `FT_GASP_DO_GRAY' are to be
   *   used for standard font rasterization only.  Independently of that,
   *   `FT_GASP_SYMMETRIC_SMOOTHING' and `FT_GASP_SYMMETRIC_GRIDFIT' are to
   *   be used if ClearType is enabled (and `FT_GASP_DO_GRIDFIT' and
   *   `FT_GASP_DO_GRAY' are consequently ignored).

   *   `ClearType' is Microsoft's implementation of LCD rendering, partly
   *   protected by patents.

   *   FT_STROKER_LINEJOIN_ROUND ::
   *     Used to render rounded line joins.  Circular arcs are used
   *     to join two lines smoothly.
   *
   *   FT_STROKER_LINEJOIN_BEVEL ::
   *     Used to render beveled line joins.  The outer corner of
   *     the joined lines is filled by enclosing the triangular
   *     region of the corner with a straight line between the
   *     outer corners of each stroke.
   *
   *   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
   *     segments a distance greater than the product of the miter
   *     limit value and the border radius), then a bevel join (see
   *     above) is used instead.  This prevents long spikes being
   *     created.  FT_STROKER_LINEJOIN_MITER_FIXED generates a miter
   *     line join as used in PostScript and PDF.
   *

   *   FT_STROKER_LINEJOIN_MITER ::
   *     Used to render mitered line joins, with variable bevels if
   *     the miter limit is exceeded.  The intersection of the
   *     strokes is clipped at a line perpendicular to the bisector
   *     of the angle between the strokes, at the distance from the
   *     intersection of the segments equal to the product of the
   *     miter limit value and the border radius.  This prevents
   *     long spikes being created.
   *     FT_STROKER_LINEJOIN_MITER_VARIABLE generates a mitered line
   *     join as used in XPS.  FT_STROKER_LINEJOIN_MITER is an alias

   *     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).
   *
   *   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).
   *

   *     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

     The 'zlib' compression library provides in-memory compression and
  decompression functions, including integrity checks of the uncompressed
  data.  This version of the library supports only one compression method
  (deflation) but other algorithms will be added later and will have the same
  stream interface.

     Compression can be done in a single step if the buffers are large
  enough (for example if an input file is mmap'ed), or can be done by
  repeated calls of the compression function.  In the latter case, the
  application must provide more input and/or consume the output
  (providing more output space) before each call.

     The library also supports reading and writing files in gzip (.gz) format
  with an interface similar to that of stdio.

     The library does not install any signal handler. The decoder checks
  the consistency of the compressed data, so the library should never
  crash even in case of corrupted input.

   opaque before calling the init function. All other fields are set by the
   compression library and must not be updated by the application.

   The opaque value provided by the application will be passed as the first
   parameter for calls of zalloc and zfree. This can be useful for custom
   memory management. The compression library attaches no meaning to the
   opaque value.

   zalloc must return Z_NULL if there is not enough memory for the object.
   If zlib is used in a multi-threaded application, zalloc and zfree must be
   thread safe.

   On 16-bit systems, the functions zalloc and zfree must be able to allocate
   exactly 65536 bytes, but will not be required to allocate more than this
   if the symbol MAXSEG_64K is defined (see zconf.h). WARNING: On MSDOS,
   pointers returned by zalloc for objects of exactly 65536 bytes *must*
   have their offset normalized to zero. The default allocation function
   provided by this library ensures this (see zutil.c). To reduce memory
   requirements and avoid any allocation of 64K objects, at the expense of
   compression ratio, compile the library with -DMAX_WBITS=14 (see zconf.h).

   The fields total_in and total_out can be used for statistics or
   progress reports. After compression, total_in holds the total size of
   the uncompressed data and may be saved for use in the decompressor
   (particularly if the decompressor wants to decompress everything in
   a single step).

ZEXTERN(int)  deflateInit OF((z_streamp strm, int level));

     Initializes the internal stream state for compression. The fields
   zalloc, zfree and opaque must be initialized before by the caller.
   If zalloc and zfree are set to Z_NULL, deflateInit updates them to
   use default allocation functions.

     The compression level must be Z_DEFAULT_COMPRESSION, or between 0 and 9:
   1 gives best speed, 9 gives best compression, 0 gives no compression at
   all (the input data is simply copied a block at a time).
   Z_DEFAULT_COMPRESSION requests a default compromise between speed and
   compression (currently equivalent to level 6).

     deflateInit returns Z_OK if success, Z_MEM_ERROR if there was not
   enough memory, Z_STREAM_ERROR if level is not a valid compression level,
   Z_VERSION_ERROR if the zlib library version (zlib_version) is incompatible

/*
    deflate compresses as much data as possible, and stops when the input
  buffer becomes empty or the output buffer becomes full. It may introduce some
  output latency (reading input without producing any output) except when
  forced to flush.

    The detailed semantics are as follows. deflate performs one or both of the
  following actions:

  - Compress more input starting at next_in and update next_in and avail_in
    accordingly. If not all input can be processed (because there is not
    enough room in the output buffer), next_in and avail_in are updated and
    processing will resume at this point for the next call of deflate().

  - Provide more output starting at next_out and update next_out and avail_out
    accordingly. This action is forced if the parameter flush is non zero.
    Forcing flush frequently degrades the compression ratio, so this parameter
    should be set only when necessary (in interactive applications).
    Some output may be provided even if flush is not set.

  Before the call of deflate(), the application should ensure that at least
  one of the actions is possible, by providing more input and/or consuming
  more output, and updating avail_in or avail_out accordingly; avail_out
  should never be zero before the call. The application can consume the
  compressed output when it wants, for example when the output buffer is full
  (avail_out == 0), or after each call of deflate(). If deflate returns Z_OK
  and with zero avail_out, it must be called again after making room in the
  output buffer because there might be more output pending.

    If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
  flushed to the output buffer and the output is aligned on a byte boundary, so
  that the decompressor can get all input data available so far. (In particular
  avail_in is zero after the call if enough output space has been provided
  before the call.)  Flushing may degrade compression for some compression
  algorithms and so it should be used only when necessary.

    If flush is set to Z_FULL_FLUSH, all output is flushed as with
  Z_SYNC_FLUSH, and the compression state is reset so that decompression can
  restart from this point if previous compressed data has been damaged or if
  random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
  the compression.

    If deflate returns with avail_out == 0, this function must be called again
  with the same value of the flush parameter and more output space (updated
  avail_out), until the flush is complete (deflate returns with non-zero
  avail_out).

    If the parameter flush is set to Z_FINISH, pending input is processed,
  pending output is flushed and deflate returns with Z_STREAM_END if there
  was enough output space; if deflate returns with Z_OK, this function must be
  called again with Z_FINISH and more output space (updated avail_out) but no
  more input data, until it returns with Z_STREAM_END or an error. After
  deflate has returned Z_STREAM_END, the only possible operations on the
  stream are deflateReset or deflateEnd.

    Z_FINISH can be used immediately after deflateInit if all the compression
  is to be done in a single step. In this case, avail_out must be at least
  0.1% larger than avail_in plus 12 bytes.  If deflate does not return
  Z_STREAM_END, then it must be called again as described above.

    deflate() sets strm->adler to the adler32 checksum of all input read
  so far (that is, total_in bytes).

    deflate() may update data_type if it can make a good guess about
  the input data type (Z_ASCII or Z_BINARY). In doubt, the data is considered
  binary. This field is only for information purposes and does not affect
  the compression algorithm in any manner.

    deflate() returns Z_OK if some progress has been made (more input
  processed or more output produced), Z_STREAM_END if all input has been
  consumed and all output has been produced (only when flush is set to
  Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example
  if next_in or next_out was NULL), Z_BUF_ERROR if no progress is possible
  (for example avail_in or avail_out was zero).

ZEXTERN(int)  inflateInit OF((z_streamp strm));

/*
    inflate decompresses as much data as possible, and stops when the input
  buffer becomes empty or the output buffer becomes full. It may some
  introduce some output latency (reading input without producing any output)
  except when forced to flush.

  The detailed semantics are as follows. inflate performs one or both of the
  following actions:

  - Decompress more input starting at next_in and update next_in and avail_in
    accordingly. If not all input can be processed (because there is not
    enough room in the output buffer), next_in is updated and processing
    will resume at this point for the next call of inflate().

  - Provide more output starting at next_out and update next_out and avail_out
    accordingly.  inflate() provides as much output as possible, until there
    is no more input data or no more space in the output buffer (see below
    about the flush parameter).

  Before the call of inflate(), the application should ensure that at least
  one of the actions is possible, by providing more input and/or consuming
  more output, and updating the next_* and avail_* values accordingly.
  The application can consume the uncompressed output when it wants, for
  example when the output buffer is full (avail_out == 0), or after each
  call of inflate(). If inflate returns Z_OK and with zero avail_out, it
  must be called again after making room in the output buffer because there
  might be more output pending.

    If the parameter flush is set to Z_SYNC_FLUSH, inflate flushes as much
  output as possible to the output buffer. The flushing behavior of inflate is
  not specified for values of the flush parameter other than Z_SYNC_FLUSH
  and Z_FINISH, but the current implementation actually flushes as much output
  as possible anyway.

    inflate() should normally be called until it returns Z_STREAM_END or an
  error. However if all decompression is to be performed in a single step
  (a single call of inflate), the parameter flush should be set to
  Z_FINISH. In this case all pending input is processed and all pending
  output is flushed; avail_out must be large enough to hold all the
  uncompressed data. (The size of the uncompressed data may have been saved
  by the compressor for this purpose.) The next operation on this stream must
  be inflateEnd to deallocate the decompression state. The use of Z_FINISH
  is never required, but can be used to inform inflate that a faster routine
  may be used for the single inflate() call.

     If a preset dictionary is needed at this point (see inflateSetDictionary
  below), inflate sets strm-adler to the adler32 checksum of the
  dictionary chosen by the compressor and returns Z_NEED_DICT; otherwise
  it sets strm->adler to the adler32 checksum of all output produced
  so far (that is, total_out bytes) and returns Z_OK, Z_STREAM_END or
  an error code as described below. At the end of the stream, inflate()
  checks that its computed adler32 checksum is equal to that saved by the
  compressor and returns Z_STREAM_END only if the checksum is correct.

    inflate() returns Z_OK if some progress has been made (more input processed
  or more output produced), Z_STREAM_END if the end of the compressed data has
  been reached and all uncompressed output has been produced, Z_NEED_DICT if a
  preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
  corrupted (input stream not conforming to the zlib format or incorrect
  adler32 checksum), Z_STREAM_ERROR if the stream structure was inconsistent
  (for example if next_in or next_out was NULL), Z_MEM_ERROR if there was not
  enough memory, Z_BUF_ERROR if no progress is possible or if there was not
  enough room in the output buffer when Z_FINISH is used. In the Z_DATA_ERROR
  case, the application may then call inflateSync to look for a good
  compression block.

                                     int  strategy));

     This is another version of deflateInit with more compression options. The
   fields next_in, zalloc, zfree and opaque must be initialized before by
   the caller.

     The method parameter is the compression method. It must be Z_DEFLATED in
   this version of the library.

     The windowBits parameter is the base two logarithm of the window size
   (the size of the history buffer).  It should be in the range 8..15 for this
   version of the library. Larger values of this parameter result in better
   compression at the expense of memory usage. The default value is 15 if
   deflateInit is used instead.

     The memLevel parameter specifies how much memory should be allocated
   for the internal compression state. memLevel=1 uses minimum memory but
   is slow and reduces compression ratio; memLevel=9 uses maximum memory
   for optimal speed. The default value is 8. See zconf.h for total memory
   usage as a function of windowBits and memLevel.

     The strategy parameter is used to tune the compression algorithm. Use the
   value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
   filter (or predictor), or Z_HUFFMAN_ONLY to force Huffman encoding only (no
   string match).  Filtered data consists mostly of small values with a
   somewhat random distribution. In this case, the compression algorithm is
   tuned to compress them better. The effect of Z_FILTERED is to force more
   Huffman coding and less string matching; it is somewhat intermediate
   between Z_DEFAULT and Z_HUFFMAN_ONLY. The strategy parameter only affects
   the compression ratio but not the correctness of the compressed output even
   if it is not set appropriately.

      deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough
   memory, Z_STREAM_ERROR if a parameter is invalid (such as an invalid
   method). msg is set to null if there is no error message.  deflateInit2 does
   not perform any compression: this will be done by deflate().
*/

/*
     Initializes the compression dictionary from the given byte sequence
   without producing any compressed output. This function must be called
   immediately after deflateInit, deflateInit2 or deflateReset, before any
   call of deflate. The compressor and decompressor must use exactly the same
   dictionary (see inflateSetDictionary).

     The dictionary should consist of strings (byte sequences) that are likely
   to be encountered later in the data to be compressed, with the most commonly
   used strings preferably put towards the end of the dictionary. Using a
   dictionary is most useful when the data to be compressed is short and can be
   predicted with good accuracy; the data can then be compressed better than
   with the default empty dictionary.

     Depending on the size of the compression data structures selected by
   deflateInit or deflateInit2, a part of the dictionary may in effect be
   discarded, for example if the dictionary is larger than the window size in
   deflate or deflate2. Thus the strings most likely to be useful should be
   put at the end of the dictionary, not at the front.

     Upon return of this function, strm->adler is set to the Adler32 value
   of the dictionary; the decompressor may later use this value to determine
   which dictionary has been used by the compressor. (The Adler32 value
   applies to the whole dictionary even if only a subset of the dictionary is
   actually used by the compressor.)

     deflateSetDictionary returns Z_OK if success, or Z_STREAM_ERROR if a
   parameter is invalid (such as NULL dictionary) or the stream state is
   inconsistent (for example if deflate has already been called for this stream
   or if the compression method is bsort). deflateSetDictionary does not

/*
   Huffman code decoding is performed using a multi-level table lookup.
   The fastest way to decode is to simply build a lookup table whose
   size is determined by the longest code.  However, the time it takes
   to build this table can also be a factor if the data being decoded
   is not very long.  The most common codes are necessarily the
   shortest codes, so those codes dominate the decoding time, and hence
   the speed.  The idea is you can have a shorter table that decodes the
   shorter, more probable codes, and then point to subsidiary tables for
   the longer codes.  The time it costs to decode the longer codes is
   then traded against the time it takes to make longer tables.

   This results of this trade are in the variables lbits and dbits
   below.  lbits is the number of bits the first level table for literal/
   length codes can decode in one step, and dbits is the same thing for
   the distance codes.  Subsequent tables are also less than or equal to
   those sizes.  These values may be adjusted either when all of the
   codes are shorter than that, in which case the longest code length in
   bits is used, or when the shortest code is *longer* than the requested
   table size, in which case the length of the shortest code in bits is
   used.

   There are two different values for the two tables, since they code a
   different number of possibilities each.  The literal/length table
   codes 286 possible values, or in a flat code, a little over eight
   bits.  The distance table codes 30 possible values, or a little less
   than five bits, flat.  The optimum values for speed end up being
   about one bit more than those, so lbits is 8+1 and dbits is 5+1.
   The optimum values may differ though from machine to machine, and
   possibly even between compilers.  Your mileage may vary.

   Notes beyond the 1.93a appnote.txt:

   1. Distance pointers never point before the beginning of the output
      stream.
   2. Distance pointers can point back across blocks, up to 32k away.
   3. There is an implied maximum of 7 bits for the bit length table and
      15 bits for the actual data.
   4. If only one code exists, then it is encoded using one bit.  (Zero
      would be more efficient, but perhaps a little confusing.)  If two
      codes exist, they are coded using one bit each (0 and 1).
   5. There is no way of sending zero distance codes--a dummy must be
      sent if there are none.  (History: a pre 2.0 version of PKZIP would
      store blocks with no distance codes, but this was discovered to be
      too harsh a criterion.)  Valid only for 1.93a.  2.04c does allow
      zero distance codes, which is sent as one code of zero bits in
      length.
   6. There are up to 286 literal/length codes.  Code 256 represents the
      end-of-block.  Note however that the static length tree defines
      288 codes just to fill out the Huffman codes.  Codes 286 and 287
      cannot be used though, since there is no length base or extra bits
      defined for them.  Similarily, there are up to 30 distance codes.
      However, static trees define 32 codes (all 5 bits) to fill out the
      Huffman codes, but the last two had better not show up in the data.
   7. Unzip can check dynamic Huffman blocks for complete code sets.
      The exception is that a single code would not be complete (see #4).
   8. The five bits following the block type is really the number of
      literal codes sent minus 257.
   9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits
      (1+6+6).  Therefore, to output three times the length, you output
      three codes (1+1+1), whereas to output four times the same length,
      you only need two codes (1+3).  Hmm.
  10. In the tree reconstruction algorithm, Code = Code + Increment
      only if BitLength(i) is not zero.  (Pretty obvious.)
  11. Correction: 4 Bits: # of Bit Length codes - 4     (4 - 19)
  12. Note: length code 284 can represent 227-258, but length code 285
      really is 258.  The last length deserves its own, short code
      since it gets used a lot in very redundant files.  The length
      258 is special since 258 - 3 (the min match length) is 255.
  13. The literal/length and distance code bit lengths are read as a
      single stream of lengths.  It is possible (and advantageous) for
      a repeat code (16, 17, or 18) to go across the boundary between
      the two sets of lengths.

     *  buffers used in the `FT_GZipFile' structure.

  /*
   *  state of LZW decompressor
   *
   *  small technical note
   *  --------------------
   *
   *  We use a few tricks in this implementation that are explained here to
   *  ease debugging and maintenance.
   *
   *  - First of all, the `prefix' and `suffix' arrays contain the suffix
   *    and prefix for codes over 256; this means that
   *
   *      prefix_of(code) == state->prefix[code-256]
   *      suffix_of(code) == state->suffix[code-256]
   *
   *    Each prefix is a 16-bit code, and each suffix an 8-bit byte.
   *
   *    Both arrays are stored in a single memory block, pointed to by
   *    `state->prefix'.  This means that the following equality is always
   *    true:
   *
   *      state->suffix == (FT_Byte*)(state->prefix + state->prefix_size)
   *
   *    Of course, state->prefix_size is the number of prefix/suffix slots
   *    in the arrays, corresponding to codes 256..255+prefix_size.
   *
   *  - `free_ent' is the index of the next free entry in the `prefix'
   *    and `suffix' arrays.  This means that the corresponding `next free
   *    code' is really `256+free_ent'.
   *
   *    Moreover, `max_free' is the maximum value that `free_ent' can reach.
   *
   *    `max_free' corresponds to `(1 << max_bits) - 256'.  Note that this
   *    value is always <= 0xFF00, which means that both `free_ent' and
   *    `max_free' can be stored in an FT_UInt variable, even on 16-bit
   *    machines.
   *
   *    If `free_ent == max_free', you cannot add new codes to the
   *    prefix/suffix table.
   *
   *  - `num_bits' is the current number of code bits, starting at 9 and
   *    growing each time `free_ent' reaches the value of `free_bits'.  The
   *    latter is computed as follows
   *
   *      if num_bits < max_bits:
   *         free_bits = (1 << num_bits)-256
   *      else:
   *         free_bits = max_free + 1
   *
   *    Since the value of `max_free + 1' can never be reached by
   *    `free_ent', `num_bits' cannot grow larger than `max_bits'.
