// This file contains data specific to blue zones.  It gets processed by
// a script to simulate `jagged arrays', with enumeration values holding
// offsets into the arrays.
//
// The format of the file is rather simple:  A section starts with three
// labels separated by whitespace and followed by a colon (everything in a
// single line); the first label gives the name of the enumeration template,
// the second the name of the array template, and the third the name of the
// `maximum' template.  The script then fills the corresponding templates
// (indicated by `@' characters around the name).
//
// A section contains one or more data records.  Each data record consists
// of two or more lines.  The first line holds the enumeration name, and the
// remaining lines the corresponding array data.
//
// There are two possible representations for array data.
//
// - A string of characters or character clusters (for example, representing
//   Aksharas, Devanagari syllables) in UTF-8 encoding enclosed in double
//   quotes, using C syntax, where the elements are separated by spaces.
//   There can be only one string per line, thus the starting and ending
//   double quote must be the first and last character in the line,
//   respectively, ignoring whitespace before and after the string.  If
//   there are multiple strings (in multiple lines), they are concatenated
//   to a single string.  In the output, a string gets represented as a
//   series of singles bytes, followed by a zero byte.  The enumeration
//   values simply hold byte offsets to the start of the corresponding
//   strings.
//
//   For strings, the `maximum' template holds the maximum number of
//   non-space characters in all strings.
//
// - Data blocks enclosed in balanced braces, which get copied verbatim and
//   which can span multiple lines.  The opening brace of a block must be
//   the first character of a line (ignoring whitespace), and the closing
//   brace the last (ignoring whitespace also).  The script appends a comma
//   character after each block and counts the number of blocks to set the
//   enumeration values.
//
//   For data blocks, the `maximum' template holds the maximum number of
//   array elements.
//
// A section can contain either strings only or data blocks only.
//
// A comment line starts with `//'; it gets removed.  A preprocessor
// directive line (using the standard syntax of `cpp') starts with `#' and
// gets copied verbatim to both the enumeration and the array.  Whitespace
// outside of a string is insignificant.
//
// Preprocessor directives are ignored while the script computes maximum
// values; this essentially means that the maximum values can easily be too
// large.  Given that the purpose of those values is to create local
// fixed-size arrays at compile time for further processing of the blue zone
// data, this isn't a problem.  Note the final zero byte of a string is not
// counted.  Note also that the count holds the number of UTF-8 encoded
// characters, not bytes.

// 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.
//
// Some scripts like Khmer need character composition to get all necessary
// blue zones, since Unicode only provides an abstract data model that
// doesn't represent all possible glyph shapes.  For such character
// clusters, the HarfBuzz library is used to convert them into the
// corresponding glyphs.  The largest glyph element (where `largest' can be
// either `largest ascender' or `largest descender') then defines the
// corresponding flat or round extremum.
//
// 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.
//
//     Mutually exclusive with `LATIN_SUB_TOP'.
//
//   LATIN_SUB_TOP
//     For all glyphs of a character cluster, compute the maximum flat
//     and round coordinate values of each component, then take the
//     smallest of the maximum values.  The idea is to get the top of
//     subscript glyphs, as used in Khmer, for example.  Note that
//     this mechanism doesn't work for ordinary ligatures.
//
//     This flags indicates a secondary blue zone: It gets removed if
//     there is a non-LATIN_SUB_TOP blue zone at the same coordinate
//     value (after scaling).
//
//     Mutually exclusive with `LATIN_TOP'.
//
//   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
// (everything separated by space characters).  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.
