* src/cff/cf2ft.c (cf2_initLocalRegionBuffer,
cf2_initGlobalRegionBuffer): It is possible for a charstring to call
a subroutine if no subroutines exist.  This is an error but should
not trigger an assert.  Split the assert to account for this.

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.

Werner Lemberg 1b5bc89754 [autofit] Fix handling of default coverages.
With this commit, the implementation of coverage handling is
completed.

* src/autofit/hbshim.c (af_get_coverage): Exit early if nothing to

zones.

* src/autofit/afcover.h: Remove coverage for oldstyle figures.
Since those digits are used in combination with ordinary letters, it
makes no sense to handle them separately.

Werner Lemberg 44aa7e0af5 [autofit] Don't combine multiple features into one set.
Combining them, as originally envisioned, would lead to much more
complicated code, as investigations have shown meanwhile.  The major
drawback is that we run out of available style slots much earlier.
However, this is only a theoretical issue since we don't support a
large number of scripts currently.

suzuki toshiya e2d2b1544f [ftrfork] Fix the face order difference between POSIX and Carbon.
The fragmented resources in Suitcase and .dfont should be reordered
when post resource for Type1 is being restored, but reordering of
sfnt resources induces the different face order.  Now the ordering
is restricted to post resource only, to prevent the different order
issue  (e.g. the face index in the fontconfig cache generated with
Carbon framework is incompatible with that by FreeType2 without
Carbon framework.)  Found by Khaled Hosny and Hin-Tak Leung.

Werner Lemberg c7b55a3473 Split off ChangeLog.24. 2013-12-23 16:42:03 +01:00
Werner Lemberg 1924134710 Introduce `coverages'.
Coverages are the interface to the HarfBuzz library to access
OpenType features for handling glyphs not addressable by the cmap.

Right now, compilation of HarfBuzz is only added to the development
build.  A solution for standard build mode will be delayed until
HarfBuzz gets split into two libraries to avoid mutual dependencies
between FreeType and HarfBuzz.

Note that this is only a first step in handling coverages, basically
providing the framework only.  Code for handling selected OpenType
features (this is, actually using the data in `afcover.h') will
follow.

* devel/ftoption.h, include/config/ftoption.h
(FT_CONFIG_OPTION_USE_HARFBUZZ): New macro.

* src/autofit/hbshim.c, src/autofit/hbshim.h, src/autofit/afcover.h:
New files.

Werner Lemberg fae3820764 Simplify header file hierarchy.
This large patch changes the header file directory layout from
`include/freetype/...' to `include/...', effectively removing one
level.  Since the file `ft2build.h' is also located in `include'
(and it stays there even after installation), all FreeType header
files are now in a single directory.

Applications that use (a) `freetype-config' or FreeType's
`pkg-config' file to get the include directory for the compiler, and
(b) the documented way for header inclusion like

  #include <ft2build.h>
  #include FT_FREETYPE_H
  ...

don't need any change to the source code.

* include/freetype/*: Move up to...
* include/*: ... this directory.

* builds/amiga/include/freetype/*: Move up to...
* builds/amiga/include/*: ... this directory.

*/*: Essentially do `s@/freetype/@/@' where appropriate.

* CMakeList.txt: Simplify.
* builds/unix/freetype-config.in, builds/unix/freetype2.in: For
`--cflags', return a single directory.
* builds/unix/install.mk (install): No longer try to remove `cache'
and `internal' subdirectories; instead, remove the `freetype'
subdirectory.

points, taken from both the OpenType specification and private
communication with Greg (which will eventually be added to the
standard).
Fix horizontal position of `pp3' and `pp4'.

* src/truetype/ttgload.h: Updated.
