-// Auto-fitter data for blue strings.
-//
-// Copyright (C) 2013-2020 by
-// David Turner, Robert Wilhelm, and Werner Lemberg.
-//
-// This file is part of the FreeType project, and may only be used,

-
-
-// 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

-//
-// 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.

- * The following explanations are mostly taken from the article

- *
- * with appropriate updates.
- *
- *
- * Segments
- *
- * `af_{cjk,latin,...}_hints_compute_segments' are the functions to
- * find segments in an outline.
- *
- * A segment is a series of at least two consecutive points that are
- * approximately aligned along a coordinate axis. The analysis to do
- * so is specific to a writing system.
- *
- *
- * Edges
- *
- * `af_{cjk,latin,...}_hints_compute_edges' are the functions to find
- * 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).
- *
- * As an example, the `latin' writing system first tries to grid-fit
- * edges, then to align segments on the edges unless it detects that
- * they form a serif.

- *
- *
- * Stems
- *
- * Stems are detected by `af_{cjk,latin,...}_hint_edges'.
- *
- * 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'.
- *
- * 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.
- *
- * The detection and handling of stems is dependent on the writing
- * system.
- *
- *
- * Serifs
- *
- * Serifs are detected by `af_{cjk,latin,...}_hint_edges'.
- *
- * In comparison to a stem, a serif (as handled by the auto-hinter
- * module that takes care of the `latin' writing system) 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).
- *
- *
- * 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 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) [currently, such points
- * aren't handled specially in the auto-hinter]
- *
- * `af_glyph_hints_align_strong_points' is the function that 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.

- * Various OpenType features might use the same glyphs at different
- * vertical positions; for example, superscript and subscript glyphs
- * could be the same. However, the auto-hinter is completely
- * 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.

- * 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.

- * The glyph loader is a simple object which is used to load a set of
- * glyphs easily. It is critical for the correct loading of composites.
- *
- * Ideally, one can see it as a stack of abstract `glyph' objects.
- *
- * loader.base Is really the bottom of the stack. It describes a
- * single glyph image made of the juxtaposition of
- * several glyphs (those `in the stack').
- *
- * loader.current Describes the top of the stack, on which a new
- * glyph can be loaded.
- *
- * Rewind Clears the stack.
- * Prepare Set up `loader.current' for addition of a new glyph
- * image.
- * Add Add the `current' glyph image to the `base' one,
- * and prepare for another one.
- *
- * The glyph loader is now a base object. Each driver used to
- * re-implement it in one way or the other, which wasted code and
- * energy.

- 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.

- FreeType font driver for BDF fonts
-
- Francesco Zappa Nardelli

-
-Introduction
-************
-
-BDF (Bitmap Distribution Format) is a bitmap font format defined by Adobe,
-which is intended to be easily understood by both humans and computers.
-This code implements a BDF driver for the FreeType library, following the
-Adobe Specification V 2.2. The specification of the BDF font format is
-available from Adobe's web site:
-
- https://www.adobe.com/content/dam/acom/en/devnet/font/pdfs/5005.BDF_Spec.pdf
-
-Many good bitmap fonts in bdf format come with XFree86 (www.XFree86.org).
-They do not define vertical metrics, because the X Consortium BDF
-specification has removed them.
-
-
-Encodings
-*********
-
-The variety of encodings that accompanies bdf fonts appears to encompass the
-small set defined in freetype.h. On the other hand, two properties that
-specify encoding and registry are usually defined in bdf fonts.
-
-I decided to make these two properties directly accessible, leaving to the
-client application the work of interpreting them. For instance:
-
-
- #include FT_INTERNAL_BDF_TYPES_H
-
- FT_Face face;
- BDF_Public_Face bdfface;
-
-
- FT_New_Face( library, ..., &face );
-
- bdfface = (BDF_Public_Face)face;
-
- if ( ( bdfface->charset_registry == "ISO10646" ) &&
- ( bdfface->charset_encoding == "1" ) )
- [..]
-
-
-Thus the driver always exports `ft_encoding_none' as face->charmap.encoding.
-FT_Get_Char_Index's behavior is unmodified, that is, it converts the ULong
-value given as argument into the corresponding glyph number.
-
-If the two properties are not available, Adobe Standard Encoding should be
-assumed.
-
-
-Anti-Aliased Bitmaps
-********************
-
-The driver supports an extension to the BDF format as used in Mark Leisher's
-xmbdfed bitmap font editor. Microsoft's SBIT tool expects bitmap fonts in
-that format for adding anti-aliased them to TrueType fonts. It introduces a
-fourth field to the `SIZE' keyword which gives the bpp value (bits per
-pixel) of the glyph data in the font. Possible values are 1 (the default),
-2 (four gray levels), 4 (16 gray levels), and 8 (256 gray levels). The
-driver returns either a bitmap with 1 bit per pixel or a pixmap with 8bits
-per pixel (using 4, 16, and 256 gray levels, respectively).
-
-
-Known problems
-**************
-
-- A font is entirely loaded into memory. Obviously, this is not the Right
- Thing(TM). If you have big fonts I suggest you convert them into PCF
- format (using the bdftopcf utility): the PCF font drive of FreeType can
- perform incremental glyph loading.
-
-When I have some time, I will implement on-demand glyph parsing.
-
-- Except for encodings properties, client applications have no visibility of
- the PCF_Face object. This means that applications cannot directly access
- font tables and must trust FreeType.
-
-- Currently, glyph names are ignored.
-
- I plan to give full visibility of the BDF_Face object in an upcoming
- revision of the driver, thus implementing also glyph names.
-
-- As I have never seen a BDF font that defines vertical metrics, vertical
- metrics are (parsed and) discarded. If you own a BDF font that defines
- vertical metrics, please let me know (I will implement them in 5-10
- minutes).

- /*
- *
- * 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.

- *
- * A cache manager is in charge of the following:
- *
- * - Maintain a mapping between generic FTC_FaceIDs and live FT_Face
- * objects. The mapping itself is performed through a user-provided
- * callback. However, the manager maintains a small cache of FT_Face
- * and FT_Size objects in order to speed up things considerably.
- *
- * - Manage one or more cache objects. Each cache is in charge of
- * holding a varying number of `cache nodes'. Each cache node
- * represents a minimal amount of individually accessible cached
- * data. For example, a cache node can be an FT_Glyph image
- * containing a vector outline, or some glyph metrics, or anything
- * else.
- *
- * Each cache node has a certain size in bytes that is added to the
- * total amount of `cache memory' within the manager.
- *
- * All cache nodes are located in a global LRU list, where the oldest
- * node is at the tail of the list.
- *
- * Each node belongs to a single cache, and includes a reference
- * count to avoid destroying it (due to caching).

- * An MRU is a list that cannot hold more than a certain number of
- * elements (`max_elements'). All elements in the list are sorted in
- * least-recently-used order, i.e., the `oldest' element is at the tail
- * of the list.
- *
- * When doing a lookup (either through `Lookup()' or `Lookup_Node()'),
- * the list is searched for an element with the corresponding key. If
- * it is found, the element is moved to the head of the list and is
- * returned.
- *
- * If no corresponding element is found, the lookup routine will try to
- * obtain a new element with the relevant key. If the list is already
- * full, the oldest element from the list is discarded and replaced by a
- * new one; a new element is added to the list otherwise.
- *
- * Note that it is possible to pre-allocate the element list nodes.
- * This is handy if `max_elements' is sufficiently small, as it saves
- * allocations/releases during the lookup process.

- * Here, we want to load a small bitmap on-demand; we thus

- * 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.

- * left_glyph ::
- * The index of the left glyph in the kern pair.
- *
- * right_glyph ::

- *
- * @Output:

- * The kerning vector. This is in font units for
- * scalable formats, and in pixels for fixed-sizes
- * formats.
- *
- * @Return:
- * FreeType error code. 0 means success.
- *
- * @Note:
- * Only horizontal layouts (left-to-right & right-to-left) are
- * supported by this function. Other layouts, or more sophisticated
- * kernings, are out of scope of this method (the basic driver
- * interface is meant to be simple).
- *
- * They can be implemented by format-specific interfaces.

-gxvalid: TrueType GX validator
-==============================
-
-
-1. What is this
----------------
-
- `gxvalid' is a module to validate TrueType GX tables: a collection of
- additional tables in TrueType font which are used by `QuickDraw GX
- Text', Apple Advanced Typography (AAT). In addition, gxvalid can
- validates `kern' tables which have been extended for AAT. Like the
- otvalid module, gxvalid uses FreeType 2's validator framework
- (ftvalid).
-
- You can link gxvalid with your program; before running your own layout
- engine, gxvalid validates a font file. As the result, you can remove
- error-checking code from the layout engine. It is also possible to
- use gxvalid as a stand-alone font validator; the `ftvalid' test
- program included in the ft2demo bundle calls gxvalid internally.
- A stand-alone font validator may be useful for font developers.
-
- This documents documents the following issues.
-
- - supported TrueType GX tables
- - fundamental validation limitations
- - permissive error handling of broken GX tables
- - `kern' table issue.
-
-
-2. Supported tables
--------------------
-
- The following GX tables are currently supported.
-
- bsln
- feat
- just
- kern(*)
- lcar
- mort
- morx
- opbd
- prop
- trak
-
- The following GX tables are currently unsupported.
-
- cvar
- fdsc
- fmtx
- fvar
- gvar
- Zapf
-
- The following GX tables won't be supported.
-
- acnt(**)
- hsty(***)
-
- The following undocumented tables in TrueType fonts designed for Apple
- platform aren't handled either.
-
- addg
- CVTM
- TPNM
- umif
-
-
- *) The `kern' validator handles both the classic and the new kern
- formats; the former is supported on both Microsoft and Apple
- platforms, while the latter is supported on Apple platforms.
-
- **) `acnt' tables are not supported by currently available Apple font
- tools.
-
- ***) There is one more Apple extension, `hsty', but it is for
- Newton-OS, not GX (Newton-OS is a platform by Apple, but it can
- use sfnt- housed bitmap fonts only). Therefore, it should be
- excluded from `Apple platform' in the context of TrueType.
- gxvalid ignores it as Apple font tools do so.
-
-
- We have checked 183 fonts bundled with MacOS 9.1, MacOS 9.2, MacOS
- 10.0, MacOS X 10.1, MSIE for MacOS, and AppleWorks 6.0. In addition,
- we have checked 67 Dynalab fonts (designed for MacOS) and 189 Ricoh
- fonts (designed for Windows and MacOS dual platforms). The number of
- fonts including TrueType GX tables are as follows.
-
- bsln: 76
- feat: 191
- just: 84
- kern: 59
- lcar: 4
- mort: 326
- morx: 19
- opbd: 4
- prop: 114
- trak: 16
-
- Dynalab and Ricoh fonts don't have GX tables except of `feat' and
- `mort'.
-
-
-3. Fundamental validation limitations
--------------------------------------
-
- TrueType GX provides layout information to libraries for font
- rasterizers and text layout. gxvalid can check whether the layout
- data in a font is conformant to the TrueType GX format specified by
- Apple. But gxvalid cannot check a how QuickDraw GX/AAT renderer uses
- the stored information.
-
- 3-1. Validation of State Machine activity
- -----------------------------------------
-
- QuickDraw GX/AAT uses a `State Machine' to provide `stateful' layout
- features, and TrueType GX stores the state transition diagram of
- this `State Machine' in a `StateTable' data structure. While the
- State Machine receives a series of glyph IDs, the State Machine
- starts with `start of text' state, walks around various states and
- generates various layout information to the renderer, and finally
- reaches the `end of text' state.
-
- gxvalid can check essential errors like:
-
- - possibility of state transitions to undefined states
- - existence of glyph IDs that the State Machine doesn't know how
- to handle
- - the State Machine cannot compute the layout information from
- given diagram
-
- These errors can be checked within finite steps, and without the
- State Machine itself, because these are `expression' errors of state
- transition diagram.
-
- There is no limitation about how long the State Machine walks
- around, so validation of the algorithm in the state transition
- diagram requires infinite steps, even if we had a State Machine in
- gxvalid. Therefore, the following errors and problems cannot be
- checked.
-
- - existence of states which the State Machine never transits to
- - the possibility that the State Machine never reaches `end of
- text'
- - the possibility of stack underflow/overflow in the State Machine
- (in ligature and contextual glyph substitutions, the State
- Machine can store 16 glyphs onto its stack)
-
- In addition, gxvalid doesn't check `temporary glyph IDs' used in the
- chained State Machines (in `mort' and `morx' tables). If a layout
- feature is implemented by a single State Machine, a glyph ID
- converted by the State Machine is passed to the glyph renderer, thus
- it should not point to an undefined glyph ID. But if a layout
- feature is implemented by chained State Machines, a component State
- Machine (if it is not the final one) is permitted to generate
- undefined glyph IDs for temporary use, because it is handled by next
- component State Machine and not by the glyph renderer. To validate
- such temporary glyph IDs, gxvalid must stack all undefined glyph IDs
- which can occur in the output of the previous State Machine and
- search them in the `ClassTable' structure of the current State
- Machine. It is too complex to list all possible glyph IDs from the
- StateTable, especially from a ligature substitution table.
-
- 3-2. Validation of relationship between multiple layout features
- ----------------------------------------------------------------
-
- gxvalid does not validate the relationship between multiple layout
- features at all.
-
- If multiple layout features are defined in TrueType GX tables,
- possible interactions, overrides, and conflicts between layout
- features are implicitly given in the font too. For example, there
- are several predefined spacing control features:
-
- - Text Spacing (Proportional/Monospace/Half-width/Normal)
- - Number Spacing (Monospaced-numbers/Proportional-numbers)
- - Kana Spacing (Full-width/Proportional)
- - Ideographic Spacing (Full-width/Proportional)
- - CJK Roman Spacing (Half-width/Proportional/Default-roman
- /Full-width-roman/Proportional)
-
- If all layout features are independently managed, we can activate
- inconsistent typographic rules like `Text Spacing=Monospace' and
- `Ideographic Spacing=Proportional' at the same time.
-
- The combinations of layout features is managed by a 32bit integer
- (one bit each for selector setting), so we can define relationships
- between up to 32 features, theoretically. But if one feature
- setting affects another feature setting, we need typographic
- priority rules to validate the relationship. Unfortunately, the
- TrueType GX format specification does not give such information even
- for predefined features.
-
-
-4. Permissive error handling of broken GX tables
-------------------------------------------------
-
- When Apple's font rendering system finds an inconsistency, like a
- specification violation or an unspecified value in a TrueType GX
- table, it does not always return error. In most cases, the rendering
- engine silently ignores such wrong values or even whole tables. In
- fact, MacOS is shipped with fonts including broken GX/AAT tables, but
- no harmful effects due to `officially broken' fonts are observed by
- end-users.
-
- gxvalid is designed to continue the validation process as long as
- possible. When gxvalid find wrong values, gxvalid warns it at least,
- and takes a fallback procedure if possible. The fallback procedure
- depends on the debug level.
-
- We used the following three tools to investigate Apple's error handling.
-
- - FontValidator (for MacOS 8.5 - 9.2) resource fork font
- - ftxvalidator (for MacOS X 10.1 -) dfont or naked-sfnt
- - ftxdumperfuser (for MacOS X 10.1 -) dfont or naked-sfnt
-
- However, all tests were done on a PowerPC based Macintosh; at present,
- we have not checked those tools on a m68k-based Macintosh.
-
- In total, we checked 183 fonts bundled to MacOS 9.1, MacOS 9.2, MacOS
- 10.0, MacOS X 10.1, MSIE for MacOS, and AppleWorks 6.0. These fonts
- are distributed officially, but many broken GX/AAT tables were found
- by Apple's font tools. In the following, we list typical violation of
- the GX specification, in fonts officially distributed with those Apple
- systems.
-
- 4-1. broken BinSrchHeader (19/183)
- ----------------------------------
-
- `BinSrchHeader' is a header of a data array for m68k platforms to
- access memory efficiently. Although there are only two independent
- parameters for real (`unitSize' and `nUnits'), BinSrchHeader has
- three additional parameters which can be calculated from `unitSize'
- and `nUnits', for fast setup. Apple font tools ignore them
- silently, so gxvalid warns if it finds and inconsistency, and always
- continues validation. The additional parameters are ignored
- regardless of the consistency.
-
- 19 fonts include such inconsistencies; all breaks are in the
- BinSrchHeader structure of the `kern' table.
-
- 4-2. too-short LookupTable (5/183)
- ----------------------------------
-
- LookupTable format 0 is a simple array to get a value from a given
- GID (glyph ID); the index of this array is a GID too. Therefore,
- the length of the array is expected to be same as the maximum GID
- value defined in the `maxp' table, but there are some fonts whose
- LookupTable format 0 is too short to cover all GIDs. FontValidator
- ignores this error silently, ftxvalidator and ftxdumperfuser both
- warn and continue. Similar problems are found in format 3 subtables
- of `kern'. gxvalid warns always and abort if the validation level
- is set to FT_VALIDATE_PARANOID.
-
- 5 fonts include too-short kern format 0 subtables.
- 1 font includes too-short kern format 3 subtable.
-
- 4-3. broken LookupTable format 2 (1/183)
- ----------------------------------------
-
- LookupTable format 2, subformat 4 covers the GID space by a
- collection of segments which are specified by `firstGlyph' and
- `lastGlyph'. Some fonts store `firstGlyph' and `lastGlyph' in
- reverse order, so the segment specification is broken. Apple font
- tools ignore this error silently; a broken segment is ignored as if
- it did not exist. gxvalid warns and normalize the segment at
- FT_VALIDATE_DEFAULT, or ignore the segment at FT_VALIDATE_TIGHT, or
- abort at FT_VALIDATE_PARANOID.
-
- 1 font includes broken LookupTable format 2, in the `just' table.
-
- *) It seems that all fonts manufactured by ITC for AppleWorks have
- this error.
-
- 4-4. bad bracketing in glyph property (14/183)
- ----------------------------------------------
-
- GX/AAT defines a `bracketing' property of the glyphs in the `prop'
- table, to control layout features of strings enclosed inside and
- outside of brackets. Some fonts give inappropriate bracket
- properties to glyphs. Apple font tools warn about this error;
- gxvalid warns too and aborts at FT_VALIDATE_PARANOID.
-
- 14 fonts include wrong bracket properties.
-
-
- 4-5. invalid feature number (117/183)
- -------------------------------------
-
- The GX/AAT extension can include 255 different layout features,
- but popular layout features are predefined (see
- https://developer.apple.com/fonts/TrueType-Reference-Manual/RM09/AppendixF.html).
- Some fonts include feature numbers which are incompatible with the
- predefined feature registry.
-
- In our survey, there are 140 fonts including `feat' table.
-
- a) 67 fonts use a feature number which should not be used.
- b) 117 fonts set the wrong feature range (nSetting). This is mostly
- found in the `mort' and `morx' tables.
-
- Apple font tools give no warning, although they cannot recognize
- what the feature is. At FT_VALIDATE_DEFAULT, gxvalid warns but
- continues in both cases (a, b). At FT_VALIDATE_TIGHT, gxvalid warns
- and aborts for (a), but continues for (b). At FT_VALIDATE_PARANOID,
- gxvalid warns and aborts in both cases (a, b).
-
- 4-6. invalid prop version (10/183)
- ----------------------------------
-
- As most TrueType GX tables, the `prop' table must start with a 32bit
- version identifier: 0x00010000, 0x00020000 or 0x00030000. But some
- fonts store nonsense binary data instead. When Apple font tools
- find them, they abort the processing immediately, and the data which
- follows is unhandled. gxvalid does the same.
-
- 10 fonts include broken `prop' version.
-
- All of these fonts are classic TrueType fonts for the Japanese
- script, manufactured by Apple.
-
- 4-7. unknown resource name (2/183)
- ------------------------------------
-
- NOTE: THIS IS NOT A TRUETYPE GX ERROR.
-
- If a TrueType font is stored in the resource fork or in dfont
- format, the data must be tagged as `sfnt' in the resource fork index
- to invoke TrueType font handler for the data. But the TrueType font
- data in `Keyboard.dfont' is tagged as `kbd', and that in
- `LastResort.dfont' is tagged as `lst'. Apple font tools can detect
- that the data is in TrueType format and successfully validate them.
- Maybe this is possible because they are known to be dfont. The
- current implementation of the resource fork driver of FreeType
- cannot do that, thus gxvalid cannot validate them.
-
- 2 fonts use an unknown tag for the TrueType font resource.
-
-5. `kern' table issues
-----------------------
-
- In common terminology of TrueType, `kern' is classified as a basic and
- platform-independent table. But there are Apple extensions of `kern',
- and there is an extension which requires a GX state machine for
- contextual kerning. Therefore, gxvalid includes a special validator
- for `kern' tables. Unfortunately, there is no exact algorithm to
- check Apple's extension, so gxvalid includes a heuristic algorithm to
- find the proper validation routines for all possible data formats,
- including the data format for Microsoft. By calling
- classic_kern_validate() instead of gxv_validate(), you can specify the
- `kern' format explicitly. However, current FreeType2 uses Microsoft
- `kern' format only, others are ignored (and should be handled in a
- library one level higher than FreeType).
-
- 5-1. History
- ------------
-
- The original 16bit version of `kern' was designed by Apple in the
- pre-GX era, and it was also approved by Microsoft. Afterwards,
- Apple designed a new 32bit version of the `kern' table. According
- to the documentation, the difference between the 16bit and 32bit
- version is only the size of variables in the `kern' header. In the
- following, we call the original 16bit version as `classic', and
- 32bit version as `new'.
-
- 5-2. Versions and dialects which should be differentiated
- ---------------------------------------------------------
-
- The `kern' table consists of a table header and several subtables.
- The version number which identifies a `classic' or a `new' version
- is explicitly written in the table header, but there are
- undocumented differences between Microsoft's and Apple's formats.
- It is called a `dialect' in the following. There are three cases
- which should be handled: the new Apple-dialect, the classic
- Apple-dialect, and the classic Microsoft-dialect. An analysis of
- the formats and the auto detection algorithm of gxvalid is described
- in the following.
-
- 5-2-1. Version detection: classic and new kern
- ----------------------------------------------
-
- According to Apple TrueType specification, there are only two
- differences between the classic and the new:
-
- - The `kern' table header starts with the version number.
- The classic version starts with 0x0000 (16bit),
- the new version starts with 0x00010000 (32bit).
-
- - In the `kern' table header, the number of subtables follows
- the version number.
- In the classic version, it is stored as a 16bit value.
- In the new version, it is stored as a 32bit value.
-
- From Apple font tool's output (DumpKERN is also tested in addition
- to the three Apple font tools in above), there is another
- undocumented difference. In the new version, the subtable header
- includes a 16bit variable named `tupleIndex' which does not exist
- in the classic version.
-
- The new version can store all subtable formats (0, 1, 2, and 3),
- but the Apple TrueType specification does not mention the subtable
- formats available in the classic version.
-
- 5-2-2. Available subtable formats in classic version
- ----------------------------------------------------
-
- Although the Apple TrueType specification recommends to use the
- classic version in the case if the font is designed for both the
- Apple and Microsoft platforms, it does not document the available
- subtable formats in the classic version.
-
- According to the Microsoft TrueType specification, the subtable
- format assured for Windows and OS/2 support is only subtable
- format 0. The Microsoft TrueType specification also describes
- subtable format 2, but does not mention which platforms support
- it. Subtable formats 1, 3, and higher are documented as reserved
- for future use. Therefore, the classic version can store subtable
- formats 0 and 2, at least. `ttfdump.exe', a font tool provided by
- Microsoft, ignores the subtable format written in the subtable
- header, and parses the table as if all subtables are in format 0.
-
- `kern' subtable format 1 uses a StateTable, so it cannot be
- utilized without a GX State Machine. Therefore, it is reasonable
- to assume that format 1 (and 3) were introduced after Apple had
- introduced GX and moved to the new 32bit version.
-
- 5-2-3. Apple and Microsoft dialects
- -----------------------------------
-
- The `kern' subtable has a 16bit `coverage' field to describe
- kerning attributes, but bit interpretations by Apple and Microsoft
- are different: For example, Apple uses bits 0-7 to identify the
- subtable, while Microsoft uses bits 8-15.
-
- In addition, due to the output of DumpKERN and FontValidator,
- Apple's bit interpretations of coverage in classic and new version
- are incompatible also. In summary, there are three dialects:
- classic Apple dialect, classic Microsoft dialect, and new Apple
- dialect. The classic Microsoft dialect and the new Apple dialect
- are documented by each vendors' TrueType font specification, but
- the documentation for classic Apple dialect is not available.
-
- For example, in the new Apple dialect, bit 15 is documented as
- `set to 1 if the kerning is vertical'. On the other hand, in
- classic Microsoft dialect, bit 1 is documented as `set to 1 if the
- kerning is horizontal'. From the outputs of DumpKERN and
- FontValidator, classic Apple dialect recognizes 15 as `set to 1
- when the kerning is horizontal'. From the results of similar
- experiments, classic Apple dialect seems to be the Endian reverse
- of the classic Microsoft dialect.
-
- As a conclusion it must be noted that no font tool can identify
- classic Apple dialect or classic Microsoft dialect automatically.
-
- 5-2-4. gxvalid auto dialect detection algorithm
- -----------------------------------------------
-
- The first 16 bits of the `kern' table are enough to identify the
- version:
-
- - if the first 16 bits are 0x0000, the `kern' table is in
- classic Apple dialect or classic Microsoft dialect
- - if the first 16 bits are 0x0001, and next 16 bits are 0x0000,
- the kern table is in new Apple dialect.
-
- If the `kern' table is a classic one, the 16bit `coverage' field
- is checked next. Firstly, the coverage bits are decoded for the
- classic Apple dialect using the following bit masks (this is based
- on DumpKERN output):
-
- 0x8000: 1=horizontal, 0=vertical
- 0x4000: not used
- 0x2000: 1=cross-stream, 0=normal
- 0x1FF0: reserved
- 0x000F: subtable format
-
- If any of reserved bits are set or the subtable bits is
- interpreted as format 1 or 3, we take it as `impossible in classic
- Apple dialect' and retry, using the classic Microsoft dialect.
-
- The most popular coverage in new Apple-dialect: 0x8000,
- The most popular coverage in classic Apple-dialect: 0x0000,
- The most popular coverage in classic Microsoft dialect: 0x0001.
-
- 5-3. Tested fonts
- -----------------
-
- We checked 59 fonts bundled with MacOS and 38 fonts bundled with
- Windows, where all font include a `kern' table.
-
- - fonts bundled with MacOS
- * new Apple dialect
- format 0: 18
- format 2: 1
- format 3: 1
- * classic Apple dialect
- format 0: 14
- * classic Microsoft dialect
- format 0: 15
-
- - fonts bundled with Windows
- * classic Microsoft dialect
- format 0: 38
-
- It looks strange that classic Microsoft-dialect fonts are bundled to
- MacOS: they come from MSIE for MacOS, except of MarkerFelt.dfont.

- 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.

- 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.

- 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.

-
-/*
- 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).
-*/
-
-
-/*
- All dynamically allocated data structures for this stream are freed.
- This function discards any unprocessed input and does not flush any

- prematurely (some input or output was discarded). In the error case,

-ZEXTERN(int) inflateInit OF((z_streamp strm));
-
- Initializes the internal stream state for decompression. The fields
- next_in, avail_in, zalloc, zfree and opaque must be initialized before by

- value depends on the compression method), inflateInit determines the
- compression method from the zlib header and allocates all data structures
- accordingly; otherwise the allocation will be deferred to the first call of
- inflate. If zalloc and zfree are set to Z_NULL, inflateInit updates them to
- use default allocation functions.

-
-ZEXTERN(int) inflate OF((z_streamp strm, int flush));
-/*
- 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

-ZEXTERN(int) deflateInit2 OF((z_streamp strm,
- int level,
- int method,
- int windowBits,
- int memLevel,
- 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
- perform any compression: this will be done by deflate().

- Sets the destination stream as a complete copy of the source stream.
-
- This function can be useful when several compression strategies will be
- tried, for example when there are several ways of pre-processing the input
- data with a filter. The streams that will be discarded should then be freed
- by calling deflateEnd. Note that deflateCopy duplicates the internal
- compression state which can be quite large, so this strategy is slow and
- can consume lots of memory.
-
- deflateCopy returns Z_OK if success, Z_MEM_ERROR if there was not

- strategy. If the compression level is changed, the input available so far
- is compressed with the old level (and may be flushed); the new level will
- take effect only at the next call of deflate().

- *
- * 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'.

- FreeType font driver for PCF fonts
-

-Introduction
-************
-
-PCF (Portable Compiled Format) is a binary bitmap font format, largely used
-in X world. This code implements a PCF driver for the FreeType library.
-Glyph images are loaded into memory only on demand, thus leading to a small
-memory footprint.
-
-Information on the PCF font format can only be worked out from
-`pcfread.c', and `pcfwrite.c', to be found, for instance, in the XFree86
-(www.xfree86.org) source tree (xc/lib/font/bitmap/).
-
-Many good bitmap fonts in bdf format come with XFree86: they can be
-compiled into the pcf format using the `bdftopcf' utility.
-
-
-Supported hardware
-******************
-
-The driver has been tested on linux/x86 and sunos5.5/sparc. In both
-cases the compiler was gcc. When back in Paris, I will test it also
-on linux/alpha.
-
-
-Encodings
-*********
-
-Use `FT_Get_BDF_Charset_ID' to access the encoding and registry.
-
-The driver always exports `ft_encoding_none' as face->charmap.encoding.
-FT_Get_Char_Index() behavior is unmodified, that is, it converts the ULong
-value given as argument into the corresponding glyph number.
-
-
-Known problems
-**************
-
-- dealing explicitly with encodings breaks the uniformity of FreeType 2
- API.
-
-- except for encodings properties, client applications have no
- visibility of the PCF_Face object. This means that applications
- cannot directly access font tables and are obliged to trust
- FreeType.
-
-- currently, glyph names and ink_metrics are ignored.
-
-I plan to give full visibility of the PCF_Face object in the next
-release of the driver, thus implementing also glyph names and
-ink_metrics.
-
-- height is defined as (ascent - descent). Is this correct?
-
-- if unable to read size information from the font, PCF_Init_Face
- sets available_size->width and available_size->height to 12.
-
-- too many english grammar errors in the readme file :-(

-Keith Packard wrote the pcf driver found in XFree86. His work is at
-the same time the specification and the sample implementation of the
-PCF format. Undoubtedly, this driver is inspired from his work.

- * the matrix is known. Other features implemented in the Capture
- * method are overshoot suppression, overshoot enforcement, and Blue

- * 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 preservation 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 propagate 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 );

- *
- * A simple technical note on how the raster works
- * -----------------------------------------------
- *
- * Converting an outline into a bitmap is achieved in several steps:
- *
- * 1 - Decomposing the outline into successive `profiles'. Each
- * profile is simply an array of scanline intersections on a given
- * dimension. A profile's main attributes are
- *
- * o its scanline position boundaries, i.e. `Ymin' and `Ymax'
- *
- * o an array of intersection coordinates for each scanline
- * between `Ymin' and `Ymax'
- *
- * o a direction, indicating whether it was built going `up' or
- * `down', as this is very important for filling rules
- *
- * o its drop-out mode
- *
- * 2 - Sweeping the target map's scanlines in order to compute segment
- * `spans' which are then filled. Additionally, this pass
- * performs drop-out control.
- *
- * The outline data is parsed during step 1 only. The profiles are
- * built from the bottom of the render pool, used as a stack. The
- * following graphics shows the profile list under construction:
- *
- * __________________________________________________________ _ _
- * | | | | |
- * | profile | coordinates for | profile | coordinates for |-->
- * | 1 | profile 1 | 2 | profile 2 |-->
- * |_________|_________________|_________|_________________|__ _ _
- *
- * ^ ^
- * | |
- * start of render pool top
- *
- * The top of the profile stack is kept in the `top' variable.
- *
- * As you can see, a profile record is pushed on top of the render
- * pool, which is then followed by its coordinates/intersections. If
- * a change of direction is detected in the outline, a new profile is
- * generated until the end of the outline.
- *
- * Note that when all profiles have been generated, the function
- * Finalize_Profile_Table() is used to record, for each profile, its
- * bottom-most scanline as well as the scanline above its upmost
- * boundary. These positions are called `y-turns' because they (sort
- * of) correspond to local extrema. They are stored in a sorted list
- * built from the top of the render pool as a downwards stack:
- *
- * _ _ _______________________________________
- * | |
- * <--| sorted list of |
- * <--| extrema scanlines |
- * _ _ __________________|____________________|
- *
- * ^ ^
- * | |
- * maxBuff sizeBuff = end of pool
- *
- * This list is later used during the sweep phase in order to
- * optimize performance (see technical note on the sweep below).
- *
- * Of course, the raster detects whether the two stacks collide and
- * handles the situation properly.

- * Computing the ascender/descender/height is tricky.
- *
- * The OpenType specification v1.8.3 says:
- *
- * [OS/2's] sTypoAscender, sTypoDescender and sTypoLineGap fields
- * are intended to allow applications to lay out documents in a
- * typographically-correct and portable fashion.
- *
- * This is somewhat at odds with the decades of backwards
- * compatibility, operating systems and applications doing whatever
- * they want, not to mention broken fonts.
- *
- * Not all fonts have an OS/2 table; in this case, we take the values
- * in the horizontal header, although there is nothing stopping the
- * values from being unreliable. Even with a OS/2 table, certain fonts
- * set the sTypoAscender, sTypoDescender and sTypoLineGap fields to 0
- * and instead correctly set usWinAscent and usWinDescent.
- *
- * As an example, Arial Narrow is shipped as four files ARIALN.TTF,
- * ARIALNI.TTF, ARIALNB.TTF and ARIALNBI.TTF. Strangely, all fonts have
- * the same values in their sTypo* fields, except ARIALNB.ttf which
- * sets them to 0. All of them have different usWinAscent/Descent
- * values. The OS/2 table therefore cannot be trusted for computing the
- * text height reliably.
- *
- * As a compromise, do the following:
- *
- * 1. If the OS/2 table exists and the fsSelection bit 7 is set
- * (USE_TYPO_METRICS), trust the font and use the sTypo* metrics.
- * 2. Otherwise, use the `hhea' table's metrics.
- * 3. If they are zero and the OS/2 table exists,
- * 1. use the OS/2 table's sTypo* metrics if they are non-zero.
- * 2. Otherwise, use the OS/2 table's usWin* metrics.

- * TABLE OVERVIEW
- * --------------
- *
- * NAME OFFSET TYPE DESCRIPTION
- *
- * format 0 USHORT must be 2
- * length 2 USHORT table length in bytes
- * language 4 USHORT Mac language code
- * keys 6 USHORT[256] sub-header keys
- * subs 518 SUBHEAD[NSUBS] sub-headers array
- * glyph_ids 518+NSUB*8 USHORT[] glyph ID array
- *
- * The `keys' table is used to map charcode high bytes to sub-headers.
- * The value of `NSUBS' is the number of sub-headers defined in the
- * table and is computed by finding the maximum of the `keys' table.
- *
- * Note that for any `n', `keys[n]' is a byte offset within the `subs'
- * table, i.e., it is the corresponding sub-header index multiplied
- * by 8.
- *
- * Each sub-header has the following format.
- *
- * NAME OFFSET TYPE DESCRIPTION
- *
- * first 0 USHORT first valid low-byte
- * count 2 USHORT number of valid low-bytes
- * delta 4 SHORT see below
- * offset 6 USHORT see below
- *
- * A sub-header defines, for each high byte, the range of valid
- * low bytes within the charmap. Note that the range defined by `first'
- * and `count' must be completely included in the interval [0..255]
- * according to the specification.
- *
- * If a character code is contained within a given sub-header, then
- * mapping it to a glyph index is done as follows.
- *
- * - The value of `offset' is read. This is a _byte_ distance from the
- * location of the `offset' field itself into a slice of the
- * `glyph_ids' table. Let's call it `slice' (it is a USHORT[], too).
- *
- * - The value `slice[char.lo - first]' is read. If it is 0, there is
- * no glyph for the charcode. Otherwise, the value of `delta' is
- * added to it (modulo 65536) to form a new glyph index.
- *
- * It is up to the validation routine to check that all offsets fall
- * within the glyph IDs table (and not within the `subs' table itself or
- * outside of the CMap).

- * format 0 USHORT must be 4
- * length 2 USHORT table length
- * in bytes
- * language 4 USHORT Mac language code
- *
- * segCountX2 6 USHORT 2*NUM_SEGS
- * searchRange 8 USHORT 2*(1 << LOG_SEGS)
- * entrySelector 10 USHORT LOG_SEGS
- * rangeShift 12 USHORT segCountX2 -

- * endCount 14 USHORT[NUM_SEGS] end charcode for

- * is 0xFFFF
- *
- * pad 14+NUM_SEGS*2 USHORT padding
- *
- * startCount 16+NUM_SEGS*2 USHORT[NUM_SEGS] first charcode for
- * each segment

- * idDelta 16+NUM_SEGS*4 SHORT[NUM_SEGS] delta for each
- * segment
- * idOffset 16+NUM_SEGS*6 SHORT[NUM_SEGS] range offset for
- * each segment; can be
- * zero
- *
- * glyphIds 16+NUM_SEGS*8 USHORT[] array of glyph ID
- * ranges
- *
- * Character codes are modelled by a series of ordered (increasing)
- * intervals called segments. Each segment has start and end codes,
- * provided by the `startCount' and `endCount' arrays. Segments must
- * not overlap, and the last segment should always contain the value
- * 0xFFFF for `endCount'.
- *
- * The fields `searchRange', `entrySelector' and `rangeShift' are better
- * ignored (they are traces of over-engineering in the TrueType
- * specification).
- *
- * Each segment also has a signed `delta', as well as an optional offset
- * within the `glyphIds' table.
- *
- * If a segment's idOffset is 0, the glyph index corresponding to any
- * charcode within the segment is obtained by adding the value of
- * `idDelta' directly to the charcode, modulo 65536.
- *
- * Otherwise, a glyph index is taken from the glyph IDs sub-array for
- * the segment, and the value of `idDelta' is added to it.
- *
- *
- * Finally, note that a lot of fonts contain an invalid last segment,
- * where `start' and `end' are correctly set to 0xFFFF but both `delta'
- * and `offset' are incorrect (e.g., `opens___.ttf' which comes with
- * OpenOffice.org). We need special code to deal with them correctly.

- * numSelector 6 ULONG number of variation sel. records
- *
- * Followed by numSelector records, each of which looks like
- *
- * varSelector 0 UINT24 Unicode codepoint of sel.
- * defaultOff 3 ULONG offset to a default UVS table
- * describing any variants to be found in

- * nonDefOff 7 ULONG offset to a non-default UVS table
- * describing any variants not in the
- * standard cmap, with GIDs here
- * (either offset may be 0 NULL)
- *
- * Selectors are sorted by code point.
- *
- * A default Unicode Variation Selector (UVS) subtable is just a list of

- *
- * numRanges 0 ULONG number of ranges following
- *
- * A range looks like
- *
- * uniStart 0 UINT24 code point of the first character in
- * this range
- * additionalCnt 3 UBYTE count of additional characters in this
- * range (zero means a range of a single
- * character)
- *
- * Ranges are sorted by `uniStart'.
- *
- * A non-default Unicode Variation Selector (UVS) subtable is a list of
- * mappings from codepoint to GID.
- *
- * numMappings 0 ULONG number of mappings
- *
- * A range looks like

- *
- * This is a new anti-aliasing scan-converter for FreeType 2. The
- * algorithm used here is _very_ different from the one in the standard
- * `ftraster' module. Actually, `ftgrays' computes the _exact_
- * coverage of the outline on each pixel cell by straight segments.
- *
- * It is based on ideas that I initially found in Raph Levien's
- * excellent LibArt graphics library (see https://www.levien.com/libart
- * for more information, though the web pages do not tell anything
- * about the renderer; you'll have to dive into the source code to
- * understand how it works).
- *
- * Note, however, that this is a _very_ different implementation
- * compared to Raph's. Coverage information is stored in a very
- * different way, and I don't use sorted vector paths. Also, it doesn't
- * use floating point values.
- *
- * Bézier segments are flattened by splitting them until their deviation
- * from straight line becomes much smaller than a pixel. Therefore, the
- * pixel coverage by a Bézier curve is calculated approximately. To
- * estimate the deviation, we use the distance from the control point
- * to the conic chord centre or the cubic chord trisection. These
- * distances vanish fast after each split. In the conic case, they vanish
- * predictably and the number of necessary splits can be calculated.
- *
- * This renderer has the following advantages:
- *
- * - It doesn't need an intermediate bitmap. Instead, one can supply a
- * callback function that will be called by the renderer to draw gray
- * spans on any target surface. You can thus do direct composition on
- * any kind of bitmap, provided that you give the renderer the right
- * callback.
- *
- * - A perfect anti-aliaser, i.e., it computes the _exact_ coverage on
- * each pixel cell by straight segments.
- *
- * - It performs a single pass on the outline (the `standard' FT2
- * renderer makes two passes).
- *
- * - It can easily be modified to render to _any_ number of gray levels
- * cheaply.
- *
- * - For small (< 80) pixel sizes, it is faster than the standard
- * renderer.

-ftrandom
-========
-
-This program expects a set of directories containing good fonts, and a set
-of extensions of fonts to be tested. It will randomly pick a font, copy it,
-introduce an error and then test it.
-
-The FreeType tests are quite basic; for each erroneous font ftrandom
-
- . forks off a new tester,
- . initializes the library,
- . opens each font in the file,
- . loads each glyph,
- . optionally reviews the contours of the glyph,
- . optionally rasterizes the glyph, and
- . closes the face.
-
-If a tester takes longer than 20 seconds, ftrandom saves the erroneous font
-and continues. If the tester exits normally or with an error, then the
-superstructure removes the test font and continues.
-
-
-Command line options
---------------------
-
- --all Test every font in the directory(ies) no matter
- what its extension.
- --check-outlines Call `FT_Outline_Decompose' on each glyph.
- --dir <dir> Append <dir> to the list of directories to search
- for good fonts. No recursive search.
- --error-count <cnt> Introduce <cnt> single-byte errors into the
- erroneous fonts (default: 1).
- --error-fraction <frac> Multiply the file size of the font by <frac> and
- introduce that many errors into the erroneous
- font file. <frac> should be in the range [0;1]
- (default: 0.0).
- --ext <ext> Add <ext> to the set of font types tested.
- --help Print out this list of options.
- --nohints Specify FT_LOAD_NO_HINTING when loading glyphs.
- --rasterize Call `FT_Render_Glyph' as well as loading it.
- --result <dir> This is the directory in which test files are
- placed.
- --test <file> Run a single test on a pre-generated testcase.
- This is done in the current process so it can be
- debugged more easily.
-
-The default font extensions tested by ftrandom are
-
- .ttf .otf .ttc .cid .pfb .pfa .bdf .pcf .pfr .fon .otb .cff
-
-The default font directory is controlled by the macro `GOOD_FONTS_DIR' in
-the source code (and can be thus specified during compilation); its default
-value is
-
- /usr/local/share/fonts
-
-The default result directory is `results' (in the current directory).
-
-
-Compilation
------------
-
-Two possible solutions.
-
-. Run ftrandom within a debugging tool like `valgrind' to catch various
- memory issues.
-
-. Compile FreeType with sanitizer flags as provided by gcc or clang, for
- example, then link it with ftrandom.

-# We now store the Adobe Glyph List in compressed form. The list is put
-# into a data structure called `trie' (because it has a tree-like
-# appearance). Consider, for example, that you want to store the
-# following name mapping:
-#
-# A => 1
-# Aacute => 6
-# Abalon => 2
-# Abstract => 4
-#
-# It is possible to store the entries as follows.
-#
-# A => 1
-# |
-# +-acute => 6
-# |
-# +-b
-# |
-# +-alon => 2
-# |
-# +-stract => 4
-#
-# We see that each node in the trie has:
-#
-# - one or more `letters'
-# - an optional value
-# - zero or more child nodes
-#
-# The first step is to call
-#
-# root = StringNode( "", 0 )
-# for word in map.values():
-# root.add( word, map[word] )
-#
-# which creates a large trie where each node has only one children.
-#
-# Executing
-#
-# root = root.optimize()
-#
-# optimizes the trie by merging the letters of successive nodes whenever
-# possible.
-#
-# Each node of the trie is stored as follows.
-#
-# - First the node's letter, according to the following scheme. We
-# use the fact that in the AGL no name contains character codes > 127.
-#
-# name bitsize description
-# ----------------------------------------------------------------
-# notlast 1 Set to 1 if this is not the last letter
-# in the word.
-# ascii 7 The letter's ASCII value.
-#
-# - The letter is followed by a children count and the value of the
-# current key (if any). Again we can do some optimization because all
-# AGL entries are from the BMP; this means that 16 bits are sufficient
-# to store its Unicode values. Additionally, no node has more than
-# 127 children.
-#
-# name bitsize description
-# -----------------------------------------
-# hasvalue 1 Set to 1 if a 16-bit Unicode value follows.
-# num_children 7 Number of children. Can be 0 only if
-# `hasvalue' is set to 1.
-# value 16 Optional Unicode value.
-#
-# - A node is finished by a list of 16bit absolute offsets to the
-# children, which must be sorted in increasing order of their first
-# letter.
-#
-# For simplicity, all 16bit quantities are stored in big-endian order.

- * Calculate the phantom points
- *

- * rsb = aw - (lsb + xmax - xmin)
- *
- * (with `aw' the advance width, `lsb' the left side bearing, and `xmin'
- * and `xmax' the glyph's minimum and maximum x value), the OpenType
- * specification defines the initial position of horizontal phantom points
- * as
- *
- * pp1 = (round(xmin - lsb), 0) ,
- * pp2 = (round(pp1 + aw), 0) .
- *
- * Note that the rounding to the grid (in the device space) is not
- * documented currently in the specification.
- *
- * However, the specification lacks the precise definition of vertical
- * phantom points. Greg Hitchcock provided the following explanation.
- *
- * - a `vmtx' table is present
- *
- * For any glyph, the minimum and maximum y values (`ymin' and `ymax')
- * are given in the `glyf' table, the top side bearing (tsb) and advance
- * height (ah) are given in the `vmtx' table. The bottom side bearing
- * (bsb) is then calculated as
- *
- * bsb = ah - (tsb + ymax - ymin) ,
- *
- * and the initial position of vertical phantom points is
- *
- * pp3 = (x, round(ymax + tsb)) ,
- * pp4 = (x, round(pp3 - ah)) .
- *
- * See below for value `x'.
- *
- * - no `vmtx' table in the font
- *
- * If there is an `OS/2' table, we set
- *
- * DefaultAscender = sTypoAscender ,
- * DefaultDescender = sTypoDescender ,
- *
- * otherwise we use data from the `hhea' table:
- *
- * DefaultAscender = Ascender ,
- * DefaultDescender = Descender .
- *
- * With these two variables we can now set
- *
- * ah = DefaultAscender - sDefaultDescender ,
- * tsb = DefaultAscender - yMax ,
- *
- * and proceed as if a `vmtx' table was present.
- *
- * Usually we have
- *
- * x = aw / 2 , (1)
- *
- * but there is one compatibility case where it can be set to
- *
- * x = -DefaultDescender -
- * ((DefaultAscender - DefaultDescender - aw) / 2) . (2)
- *
- * and another one with
- *
- * x = 0 . (3)
- *
- * In Windows, the history of those values is quite complicated,
- * depending on the hinting engine (that is, the graphics framework).
- *
- * framework from to formula

- * GDI+ Windows XP Windows 7 (2)

- *
- * @Description:
- * A function used to load a single glyph within a given glyph slot,
- * for a given size.
- *
- * @Input:
- * glyph ::
- * A handle to a target slot object where the glyph
- * will be loaded.
- *
- * size ::
- * A handle to the source face size at which the glyph
- * must be scaled/loaded.
- *
- * glyph_index ::
- * The index of the glyph in the font file.
- *
- * load_flags ::
- * A flag indicating what to load for this glyph. The
- * FT_LOAD_XXX constants can be used to control the
- * glyph loading process (e.g., whether the outline
- * should be scaled, whether to load bitmaps or not,
- * whether to hint the outline, etc).
- *
- * @Return:
- * FreeType error code. 0 means success.

- * Before, the following led to different line metrics between default
- * outline and instances, visible when e.g. the default outlines were
- * used as the regular face and instances for everything else:
- *
- * 1. sfnt_load_face applied the hhea metrics by default.
- * 2. This code later applied the typo metrics by default, regardless of
- * whether they were actually changed or the font had the OS/2 table's
- * fsSelection's bit 7 (USE_TYPO_METRICS) set.

- /*
- * FreeType supports ClearType-like hinting of TrueType fonts through
- * the version 40 interpreter. This is achieved through several hacks
- * in the base (v35) interpreter, as detailed below.
- *
- * ClearType is an umbrella term for several rendering techniques
- * employed by Microsoft's various GUI and rendering toolkit
- * implementations, most importantly: subpixel rendering for using the
- * RGB subpixels of LCDs to approximately triple the perceived
- * resolution on the x-axis and subpixel hinting for positioning stems
- * on subpixel borders. TrueType programming is explicit, i.e., fonts
- * must be programmed to take advantage of ClearType's possibilities.
- *
- * When ClearType was introduced, it seemed unlikely that all fonts
- * would be reprogrammed, so Microsoft decided to implement a backward
- * compatibility mode. It employs several simple to complicated
- * assumptions and tricks, many of them font-dependent, that modify the
- * interpretation of the bytecode contained in these fonts to retrofit
- * them into a ClearType-y look. The quality of the results varies.
- * Most (web)fonts that were released since then have come to rely on
- * these hacks to render correctly, even some of Microsoft's flagship
- * fonts (e.g., Calibri, Cambria, Segoe UI).
- *
- * FreeType's minimal subpixel hinting code (interpreter version 40)
- * employs a small list of font-agnostic hacks loosely based on the
- * public information available on Microsoft's compatibility mode[2].
- * The focus is on modern (web)fonts rather than legacy fonts that were
- * made for monochrome rendering. It will not match ClearType rendering
- * exactly. Unlike the `Infinality' code (interpreter version 38) that
- * came before, it will not try to toggle hacks for specific fonts for
- * performance and complexity reasons. It will fall back to version 35
- * behavior for tricky fonts[1] or when monochrome rendering is
- * requested.
- *
- * Major hacks
- *
- * - Any point movement on the x axis is ignored (cf. `Direct_Move' and
- * `Direct_Move_X'). This has the smallest code footprint and single
- * biggest effect. The ClearType way to increase resolution is
- * supersampling the x axis, the FreeType way is ignoring instructions
- * on the x axis, which gives the same result in the majority of
- * cases.
- *
- * - Points are not moved post-IUP (neither on the x nor on the y axis),
- * except the x component of diagonal moves post-IUP (cf.
- * `Direct_Move', `Direct_Move_Y', `Move_Zp2_Point'). Post-IUP
- * changes are commonly used to `fix' pixel patterns which has little
- * use outside monochrome rendering.
- *
- * - SHPIX and DELTAP don't execute unless moving a composite on the
- * y axis or moving a previously y touched point. SHPIX additionally
- * denies movement on the x axis (cf. `Ins_SHPIX' and `Ins_DELTAP').
- * Both instructions are commonly used to `fix' pixel patterns for
- * monochrome or Windows's GDI rendering but make little sense for
- * FreeType rendering. Both can distort the outline. See [2] for
- * details.
- *
- * - The hdmx table and modifications to phantom points are ignored.
- * Bearings and advance widths remain unchanged (except rounding them
- * outside the interpreter!), cf. `compute_glyph_metrics' and
- * `TT_Hint_Glyph'. Letting non-native-ClearType fonts modify spacing
- * might mess up spacing.
- *
- * Minor hacks
- *
- * - FLIPRGON, FLIPRGOFF, and FLIPPT don't execute post-IUP. This
- * prevents dents in e.g. Arial-Regular's `D' and `G' glyphs at
- * various sizes.
- *
- * (Post-IUP is the state after both IUP[x] and IUP[y] have been
- * executed.)
- *
- * The best results are achieved for fonts that were from the outset
- * designed with ClearType in mind, meaning they leave the x axis mostly
- * alone and don't mess with the `final' outline to produce more
- * pleasing pixel patterns. The harder the designer tried to produce
- * very specific patterns (`superhinting') for pre-ClearType-displays,
- * the worse the results.
- *
- * Microsoft defines a way to turn off backward compatibility and
- * interpret instructions as before (called `native ClearType')[2][3].
- * The font designer then regains full control and is responsible for
- * making the font work correctly with ClearType without any
- * hand-holding by the interpreter or rasterizer[4]. The v40
- * interpreter assumes backward compatibility by default, which can be
- * turned off the same way by executing the following in the control
- * program (cf. `Ins_INSTCTRL').
- *
- * #PUSH 4,3

- * [1] Tricky fonts as FreeType defines them rely on the bytecode
- * interpreter to display correctly. Hacks can interfere with them,
- * so they get treated like native ClearType fonts (v40 with
- * backward compatibility turned off). Cf. `TT_RunIns'.
- *
- * [2] Proposed by Microsoft's Greg Hitchcock in
- * https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx
- *
- * [3] Beat Stamm describes it in more detail:
- * http://rastertragedy.com/RTRCh4.htm#Sec12.
- *
- * [4] The list of `native ClearType' fonts is small at the time of this
- * writing; I found the following on a Windows 10 Update 1511
- * installation: Constantia, Corbel, Sitka, Malgun Gothic, Microsoft
- * JhengHei (Bold and UI Bold), Microsoft YaHei (Bold and UI Bold),
- * SimSun, NSimSun, and Yu Gothic.

- * A note regarding non-squared pixels:
- *
- * (This text will probably go into some docs at some time; for now, it
- * is kept here to explain some definitions in the TT_Size_Metrics
- * record).
- *
- * The CVT is a one-dimensional array containing values that control
- * certain important characteristics in a font, like the height of all
- * capitals, all lowercase letter, default spacing or stem width/height.
- *
- * These values are found in FUnits in the font file, and must be scaled
- * to pixel coordinates before being used by the CVT and glyph programs.
- * Unfortunately, when using distinct x and y resolutions (or distinct x
- * and y pointsizes), there are two possible scalings.
- *
- * A first try was to implement a `lazy' scheme where all values were
- * scaled when first used. However, while some values are always used
- * in the same direction, some others are used under many different
- * circumstances and orientations.
- *
- * I have found a simpler way to do the same, and it even seems to work
- * in most of the cases:
- *
- * - All CVT values are scaled to the maximum ppem size.
- *
- * - When performing a read or write in the CVT, a ratio factor is used
- * to perform adequate scaling. Example:
- *
- * x_ppem = 14
- * y_ppem = 10
- *
- * We choose ppem = x_ppem = 14 as the CVT scaling size. All cvt
- * entries are scaled to it.
- *
- * x_ratio = 1.0
- * y_ratio = y_ppem/ppem (< 1.0)
- *
- * We compute the current ratio like:
- *
- * - If projVector is horizontal,
- * ratio = x_ratio = 1.0
- *
- * - if projVector is vertical,
- * ratio = y_ratio
- *
- * - else,
- * ratio = sqrt( (proj.x * x_ratio) ^ 2 + (proj.y * y_ratio) ^ 2 )
- *
- * Reading a cvt value returns
- * ratio * cvt[index]
- *
- * Writing a cvt value in pixels:
- * cvt[index] / ratio
- *
- * The current ppem is simply
- * ratio * ppem

- * These rules affect how the TT Interpreter does hinting, with the

- * Some of these rules are fixes that go above and beyond the
- * stated techniques in the MS whitepaper on Cleartype, due to
- * artifacts in many glyphs. So, these rules make some glyphs render
- * better than they do in the MS rasterizer.
- *
- * "" string or 0 int/char indicates to apply to all glyphs.
- * "-" used as dummy placeholders, but any non-matching string works.
- *
- * Some of this could arguably be implemented in fontconfig, however:
- *
- * - Fontconfig can't set things on a glyph-by-glyph basis.
- * - The tweaks that happen here are very low-level, from an average
- * user's point of view and are best implemented in the hinter.
- *
- * The goal is to make the subpixel hinting techniques as generalized
- * as possible across all fonts to prevent the need for extra rules such
- * as these.
- *
- * The rule structure is designed so that entirely new rules can easily
- * be added when a new compatibility feature is discovered.

- * @Function:
- * Get_Kerning
- *
- * @Description:
- * A driver method used to return the kerning vector between two
- * glyphs of the same face.
- *
- * @Input:
- * face ::
- * A handle to the source face object.
- *
- * left_glyph ::
- * The index of the left glyph in the kern pair.
- *
- * right_glyph ::
- * The index of the right glyph in the kern pair.
- *
- * @Output:
- * kerning ::
- * The kerning vector. This is in font units for
- * scalable formats, and in pixels for fixed-sizes
- * formats.
- *
- * @Return:
- * FreeType error code. 0 means success.
- *
- * @Note:
- * Only horizontal layouts (left-to-right & right-to-left) are
- * supported by this function. Other layouts, or more sophisticated
- * kernings are out of scope of this method (the basic driver
- * interface is meant to be simple).
- *
- * They can be implemented by format-specific interfaces.

- *
- * This is the new and improved Type 1 data loader for FreeType 2. The
- * old loader has several problems: it is slow, complex, difficult to
- * maintain, and contains incredible hacks to make it accept some
- * ill-formed Type 1 fonts without hiccup-ing. Moreover, about 5% of
- * the Type 1 fonts on my machine still aren't loaded correctly by it.
- *
- * This version is much simpler, much faster and also easier to read and
- * maintain by a great order of magnitude. The idea behind it is to
- * _not_ try to read the Type 1 token stream with a state machine (i.e.
- * a Postscript-like interpreter) but rather to perform simple pattern
- * matching.
- *
- * Indeed, nearly all data definitions follow a simple pattern like
- *
- * ... /Field <data> ...
- *
- * where <data> can be a number, a boolean, a string, or an array of
- * numbers. There are a few exceptions, namely the encoding, font name,
- * charstrings, and subrs; they are handled with a special pattern
- * matching routine.
- *
- * All other common cases are handled very simply. The matching rules
- * are defined in the file `t1tokens.h' through the use of several
- * macros calls PARSE_XXX. This file is included twice here; the first
- * time to generate parsing callback functions, the second time to
- * generate a table of keywords (with pointers to the associated
- * callback functions).
- *
- * The function `parse_dict' simply scans *linearly* a given dictionary
- * (either the top-level or private one) and calls the appropriate
- * callback when it encounters an immediate keyword.
- *
- * This is by far the fastest way one can find to parse and read all
- * data.
- *
- * This led to tremendous code size reduction. Note that later, the
- * glyph loader will also be _greatly_ simplified, and the automatic
- * hinter will replace the clumsy `t1hinter'.

- * This driver implements Type42 fonts as described in the
- * Technical Note #5012 from Adobe, with these limitations:
- *
- * 1) CID Fonts are not currently supported.
- * 2) Incremental fonts making use of the GlyphDirectory keyword
- * will be loaded, but the rendering will be using the TrueType
- * tables.
- * 3) As for Type1 fonts, CDevProc is not supported.
- * 4) The Metrics dictionary is not supported.
- * 5) AFM metrics are not supported.
- *
- * In other words, this driver supports Type42 fonts derived from
- * TrueType fonts in a non-CID manner, as done by usual conversion
- * programs.
