+   *   containing the combination of the characters `T', `E', and `L' to
+   *   form a `TEL' ligature.
+   *
+   *   By default, this is @FT_AUTOHINTER_SCRIPT_LATIN.  Using the
+   *   `default-script' property, this default value can be changed.
+   *
+   *   {
+   *     FT_Library  library;
+   *     FT_UInt     default_script = FT_AUTOHINTER_SCRIPT_NONE;
+   *
+   *
+   *     FT_Init_FreeType( &library );
+   *
+   *     FT_Property_Set( library, "autofitter",
+   *                               "default-script", &default_script );
+   *   }
+   *
+   * @note:
+   *   This property can be used with @FT_Property_Get also.
+   *
+   *   It's important to use the right timing for changing this value: The
+   *   creation of the glyph-to-script map that eventually uses the
+   *   default script value gets triggered either by setting or reading a
+   *   face-specific property like @glyph-to-script-map, or by auto-hinting
+   *   any glyph from that face.  In particular, if you have already created
+   *   an @FT_Face structure but not loaded any glyph (using the
+   *   auto-hinter), a change of the default script will affect this face.

+// The blue zone stringsets, as used in the script styles, cf. `afstyles.h'.
+//
+// The AF_BLUE_PROPERTY_XXX flags are defined in `afblue.h'; here some
+// explanations.
+//
+// A blue zone in general is defined by a reference and an overshoot line.
+// During the hinting process, all coordinate values between those two lines
+// are set equal to the reference value, provided that the blue zone is not
+// wider than 0.75 pixels (otherwise the blue zone gets ignored).  All
+// entries must have `AF_BLUE_STRING_MAX' as the final line.
+//
+// During the glyph analysis, edges are sorted from bottom to top, and then
+// sequentially checked, edge by edge, against the blue zones in the order
+// given below.
+//
+//
+// latin auto-hinter
+// -----------------
+//
+// Characters in a blue string are automatically classified as having a flat
+// (reference) or a round (overshoot) extremum.  The blue zone is then set
+// up by the mean values of all flat extrema and all round extrema,
+// respectively.  Only horizontal blue zones (i.e., adjusting vertical
+// coordinate values) are supported.
+//
+// For the latin auto-hinter, the overshoot should be larger than the
+// reference for top zones, and vice versa for bottom zones.
+//
+//   LATIN_TOP
+//     Take the maximum flat and round coordinate values of the blue string
+//     characters for computing the blue zone's reference and overshoot
+//     values.
+//
+//     If not set, take the minimum values.
+//
+//   LATIN_NEUTRAL
+//     Ignore round extrema and define the blue zone with flat values only.
+//     Both top and bottom of contours can match.  This is useful for
+//     scripts like Devanagari where vowel signs attach to the base
+//     character and are implemented as components of composite glyphs.
+//
+//     If not set, both round and flat extrema are taken into account.
+//     Additionally, only the top or the bottom of a contour can match,
+//     depending on the LATIN_TOP flag.
+//
+//     Neutral blue zones should always follow non-neutral blue zones.
+//
+//   LATIN_X_HEIGHT
+//     Scale all glyphs vertically from the corresponding script to make the
+//     reference line of this blue zone align on the grid.  The scaling
+//     takes place before all other blue zones get aligned to the grid.
+//     Only one blue character string of a script style can have this flag.
+//
+//   LATIN_LONG
+//     Apply an additional constraint for blue zone values: Don't
+//     necessarily use the extremum as-is but a segment of the topmost (or
+//     bottommost) contour that is longer than a heuristic threshold, and
+//     which is not too far away vertically from the real extremum.  This
+//     ensures that small bumps in the outline are ignored (for example, the
+//     `vertical serifs' found in many Hebrew glyph designs).
+//
+//     The segment must be at least EM/25 font units long, and the distance
+//     to the extremum must be smaller than EM/4.
+//
+//
+// cjk auto-hinter
+// ---------------
+//
+// Characters in a blue string are *not* automatically classified.  Instead,
+// first come the characters used for the overshoot value, then the
+// character `|', then the characters used for the reference value.  The
+// blue zone is then set up by the mean values of all reference values and
+// all overshoot values, respectively.  Both horizontal and vertical blue
+// zones (i.e., adjusting vertical and horizontal coordinate values,
+// respectively) are supported.
+//
+// For the cjk auto-hinter, the overshoot should be smaller than the
+// reference for top zones, and vice versa for bottom zones.
+//
+//   CJK_TOP
+//     Take the maximum flat and round coordinate values of the blue string
+//     characters.  If not set, take the minimum values.
+//
+//   CJK_RIGHT
+//     A synonym for CJK_TOP.  If CJK_HORIZ is set, this flag indicates the
+//     right blue zone, taking horizontal maximum values.
+//
+//   CJK_HORIZ
+//     Define a blue zone for horizontal hinting (i.e., vertical blue
+//     zones).  If not set, this is a blue zone for vertical hinting.

+   *  Usually, a font contains more glyphs than can be addressed by its
+   *  character map.
+   *
+   *  In the PostScript font world, encoding vectors specific to a given
+   *  task are used to select such glyphs, and these glyphs can be often
+   *  recognized by having a suffix in its glyph names.  For example, a
+   *  superscript glyph `A' might be called `A.sup'.  Unfortunately, this
+   *  naming scheme is not standardized and thus unusable for us.
+   *
+   *  In the OpenType world, a better solution was invented, namely
+   *  `features', which cleanly separate a character's input encoding from
+   *  the corresponding glyph's appearance, and which don't use glyph names
+   *  at all.  For our purposes, and slightly generalized, an OpenType
+   *  feature is a name of a mapping that maps character codes to
+   *  non-standard glyph indices (features get used for other things also).
+   *  For example, the `sups' feature provides superscript glyphs, thus
+   *  mapping character codes like `A' or `B' to superscript glyph
+   *  representation forms.  How this mapping happens is completely
+   *  uninteresting to us.
+   *
+   *  For the auto-hinter, a `coverage' represents all glyphs of an OpenType
+   *  feature collected in a set (as listed below) that can be hinted
+   *  together.  To continue the above example, superscript glyphs must not
+   *  be hinted together with normal glyphs because the blue zones
+   *  completely differ.
+   *
+   *  Note that FreeType itself doesn't compute coverages; it only provides
+   *  the glyphs addressable by the default Unicode character map.  Instead,
+   *  we use the HarfBuzz library (if available), which has many functions
+   *  exactly for this purpose.
+   *
+   *  AF_COVERAGE_DEFAULT is special: It should cover everything that isn't
+   *  listed separately (including the glyphs addressable by the character
+   *  map).  In case HarfBuzz isn't available, it exactly covers the glyphs
+   *  addressable by the character map.

+     * agnostic of OpenType features after the feature analysis has been
+     * completed: The engine then simply receives a glyph index and returns a
+     * hinted and usually rendered glyph.
+     *
+     * Consider the superscript feature of font `pala.ttf': Some of the
+     * glyphs are `real', this is, they have a zero vertical offset, but
+     * most of them are small caps glyphs shifted up to the superscript
+     * position (this is, the `sups' feature is present in both the GSUB and
+     * GPOS tables).  The code for blue zones computation actually uses a
+     * feature's y offset so that the `real' glyphs get correct hints.  But
+     * later on it is impossible to decide whether a glyph index belongs to,
+     * say, the small caps or superscript feature.
+     *
+     * For this reason, we don't assign a style to a glyph if the current
+     * feature covers the glyph in both the GSUB and the GPOS tables.  This
+     * is quite a broad condition, assuming that
+     *
+     *   (a) glyphs that get used in multiple features are present in a
+     *       feature without vertical shift,
+     *
+     * and
+     *
+     *   (b) a feature's GPOS data really moves the glyph vertically.
+     *
+     * Not fulfilling condition (a) makes a font larger; it would also
+     * reduce the number of glyphs that could be addressed directly without
+     * using OpenType features, so this assumption is rather strong.
+     *
+     * Condition (b) is much weaker, and there might be glyphs which get
+     * missed.  However, the OpenType features we are going to handle are
+     * primarily located in GSUB, and HarfBuzz doesn't provide an API to
+     * directly get the necessary information from the GPOS table.  A
+     * possible solution might be to directly parse the GPOS table to find
+     * out whether a glyph gets shifted vertically, but this is something I
+     * would like to avoid if not really necessary.
+     *
+     * Note that we don't follow this logic for the default coverage. 
+     * Complex scripts like Devanagari have mandatory GPOS features to
+     * position many glyph elements, using mark-to-base or mark-to-ligature
+     * tables; the number of glyphs missed due to condition (b) would be far
+     * too large.
