* The following explanations are mostly taken from the article

* by David Turner and Werner Lemberg
*
* https://www.tug.org/TUGboat/Articles/tb24-3/lemberg.pdf
*
* 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.
*

* +--------------->------------------+
* D E
*
*
* 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.
