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

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

 Encodings
 *********
 
-The variety of encodings that accompanies pcf fonts appears to encompass the
-small set defined in freetype.h.  On the other hand, each pcf font defines
-two properties that specify encoding and registry.
+Use `FT_Get_BDF_Charset_ID' to access the encoding and registry.
 
-I decided to make these two properties directly accessible, leaving to the
-client application the work of interpreting them.  For instance:
-
-  #include "pcftypes.h"  /* include/freetype/internal/pcftypes.h */
-
-  FT_Face     face;
-  PCF_Public_Face  pcfface;
-
-  FT_New_Face( library,..., &face );
-
-  pcfface = (PCF_Public_Face)face;
-
-  if ((pcfface->charset_registry == "ISO10646") &&
-        (pcfface->charset_encoding) == "1")) [..]
-
-Thus the driver always export `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.
+The driver always exports `ft_encoding_none' as face->charmap.encoding.
