Werner Lemberg 03987bfdbf A better fix for Savannah bug #43392.
Suggested by Doug Felt <dougfelt@gmail.com>.

`vertAdvance' to zero...

* src/truetype/ttgload.c (TT_Load_Glyph): ... and set here a default
value for `vertAdvance' based on `linearVertAdvance' in case

Werner Lemberg c576bb0d21 [autofit] Add blue-zone support for Devanagari.
This essentially moves the Devanagari script from the `Indic' hinter
to the `Latin' hinter.  Thanks to Girish Dalvi
<girish.dalvi@gmail.com> for guidance with blue zone characters!

Werner Lemberg ccfc4b4c4e [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

U+0913 or U+0914).

Werner Lemberg 98e510ee94 [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
used.

Werner Lemberg 8a94b1efd6 [autofit] Redesign the recognition algorithm of strong points.
In particular, local extrema without horizontal or vertical segments
are better recognized:

  + A                + D
   \                /
    \              /
     \            /
      \          /
       \        + C
        \    /
       B +/

If the distances AB and CD are large, point B wasn't previously
detected as an extremum since the `ft_corner_is_flat' function
`swallowed' BC regardless of its direction, tagging point B as weak.
The next iteration started at B and made `ft_corner_is_flat' swallow
point C, tagging it as weak also, et voilà.

To improve that, another pass gets now performed before calling
`ft_corner_is_flat' to improve the `topology' of an outline: A
sequence of non-horizontal or non-vertical vectors that point into
the same quadrant are handled as a single, large vector.

Additionally, distances of near points are now accumulated, which
makes the auto-hinter handle them as if they were prepended to the
next non-near vector.

This generally improves the auto-hinter's rendering results.

* src/autofit/afhints.c (af_glyph_hints_reload): Implement it.

* src/autofit/afhints.h (AF_FLAGS): Remove no longer used flag
`AF_FLAG_NEAR'.

Werner Lemberg 71f53e122b [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.

Werner Lemberg 9a56764037 [bdf] Fix Savannah bug #41692.
bdflib puts data from the input stream into a buffer in chunks of
1024 bytes.  The data itself gets then parsed line by line, simply
increasing the current pointer into the buffer; if the search for
the final newline character exceeds the buffer size, more data gets
read.

However, in case the current line's end is very near to the buffer
end, and the keyword to compare with is longer than the current
line's length, an out-of-bounds read might happen since `memcmp'
doesn't stop properly at the string end.

* src/bdf/bdflib.c: s/ft_memcmp/ft_strncmp/ to make comparisons
stop at string ends.

Werner Lemberg 0d97744d81 [autofit] Fix Indic scripts.
Split the single, incorrect Indic entry into separate scripts so
that the covered ranges are the same: Bengali, Devanagari, Gujarati,
Gurmukhi, Kannada, Limbu, Malayalam, Oriya, Sinhala, Sundanese,
Syloti Nagri, Tamil, Telugu, and Tibetan.  At the same time, remove
entries for Meetai Mayak and Sharada – the Unicode ranges were
incorrect (and nobody has complained about that), fonts are scarce
for those scripts, and the Indic auto-hinter support is rudimentary
anyways.

* src/autofit/afscript.h: Updated, using AF_CONFIG_OPTION_INDIC and
AF_CONFIG_OPTION_CJK.

* src/autofit/afstyles.h (STYLE_DEFAULT_INDIC): New auxiliary macro.
Use it, together with AF_CONFIG_OPTION_INDIC and
AF_CONFIG_OPTION_CJK, to update.

* src/autofit/afranges.c [AF_CONFIG_OPTION_INDIC]: Updated.
[!AF_CONFIG_OPTION_INDIC, !AF_CONFIG_OPTION_CJK]: Removed.
Sort entries by tags.
