function type.

[autofit] Introduce neutral blue zones to the latin module.
Such blue zones match either the top or the bottom of a contour. We
need them for scripts where accent-like elements directly touch the
base character (for example, some vowel signs in Devanagari, cf.
U+0913 or U+0914).

property.

[autofit] Fix Savannah bug #42148.
The adaptation of the cjk auto-hinter module to blue stringsets in
2013-08-25 had three severe bugs. Mea culpa.
1. Contrary to the latin auto-hinter, characters for reference and
overshoot values of a blue zone are specified separately. Due to
the screwed-up change it didn't work at all.
2. A boolean comparison was erroneously replaced with a cast,
causing invalid results with the `^' operator later on. The
visual artifact caused by this problem is the topic of the bug
report.
3. Two flag values were inverted, causing incorrect assignment of
reference and overshoot values.
* src/autofit/afblue.dat: Fix CJK bluestrings, introducing a new
syntax to have both reference and overshoot characters in a single
string. This is error #1.
Add extensive comments.
* src/autofit/afblue.hin (AF_BLUE_PROPERTY_CJK_FILL): Removed, no
longer used.
(AF_BLUE_PROPERTY_CJK_TOP, AF_BLUE_PROPERTY_CJK_HORIZ): Fix values.
This is error #3.
* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
* src/autofit/afcjk.c (af_cjk_metrics_init_blues): Correct error #1.
Use character `|' to separate characters for reference and overshoot
values.
Improve tracing messages, synchronizing them with the latin
auto-hinter.
(af_cjk_hints_compute_blue_edges): Fix value of `is_top_right_blue'.
This is error #2.
(af_cjk_align_linked_edge): Add tracing message.
* src/autofit/afcjk.h (AF_CJK_IS_FILLED_BLUE): Removed, no longer

[autofit] Improve scoring algorithm for identifying stems.
Problem reported by Karsten Lücke <karsten.luecke@kltf.de>.
The new algorithm takes care of the width of stems: If the distance
between two segments is larger than the largest stem width, the
demerits quickly increase for larger distances. This improves
hinting of slanted fonts (especially if the inner parts of serifs
have non-horizontal `shoulders'), avoiding false stem links.
* src/autofit/aflatin.c (af_latin_hints_link_segments): Use largest
stem width (if available) to compute better demerits for distances
between stems.
(af_latin_hints_detect_features): Pass stem width array and array
size.
(af_latin_metrics_init_widths): Updated to use original algorithm.
(af_latin_hints_apply): Updated to use new algorithm.
* src/autofit/aflatin.h: Updated.
* src/autofit/afcjk.c: Updated.

[autofit] Introduce `writing systems'.
This patch adds a new top level to the auto-hinter's script class
hierarchy. It defines `writing systems' which can contain multiple
scripts.
For example, the `latin' writing system (in file `aflatin.c') is
able to support scripts like Latin, Cyrillic, Armenian, etc., which
can be handled similarly.
Scripts are now named using four-letter OpenType tags.
* src/autofit/aftypes.h (AF_ScriptClassRec): Move relevant members
to...
(AF_WritingSystemClassRec): This new structure. It holds pointers
to functions which can be shared among related scripts.
(AF_WritingSystem): New enumeration.

[autofit] Fix segment classification for blue zones.
The old code (essentially unchanged since the very beginning)
incorrectly handled this configuration
x -o- x
/ \
/ \
/ \
o o
as flat and this
o o
/ /
x| x|
| |
o---------------o
as round. (`o' and `x' are on and off points, respectively).
This is a major change which should improve the rendering results
enormously for many TrueType fonts, especially in the range approx.
20-40ppem, fixing the appearance of many overshoots.
* src/autofit/aflatin.c (af_latin_metrics_init_blues): Look at the
first and last points of the segment, not the points right before
and after.

[autofit] Implement Infinality's `increase glyph heights'.
This is an improved version of a similar fix contained in the
so-called `Infinality patch', taken from
http://www.infinality.net/fedora/linux/zips/freetype-infinality-2.4.10-20120616_01-x86_64.tar.bz2
which addresses various enhancements of the auto-hinter. Without
properties to control a module's metadata it wasn't possible to
adapt the patches because everything was originally controlled by
environment variables which I consider not suitable in general.
A patch to control `increase_x_height' follows.
* src/autofit/afglobal.h (AF_PROP_INCREASE_X_HEIGHT_MIN,
AF_PROP_INCREASE_X_HEIGHT_MAX): New macros.
(AF_FaceGlobalsRec): Add `increase_x_height' member.
* src/autofit/afglobal.c (af_face_globals_new): Initialize it.
* src/autofit/aflatin.c (af_latin_metrics_scale_dim),
