+
+ * builds/unix/configure.raw: Use `x"${xxx}" != xno' style.
+
+2014-03-04 Werner Lemberg <wl@gnu.org>
+
+ Minor fix for `make devel'.
+
+ * builds/freetype.mk (INCLUDE_FLAGS) [DEVEL_DIR]: Don't use
+ pkg-config for bzip2 since not all GNU/Linux distributions have
+ `bzip2.pc' (and the header file `bzlib.h' is located in /usr/include
+ normally).
+
+2014-03-04 Sean McBride <sean@rogue-research.com>

+
+2014-03-03 Werner Lemberg <wl@gnu.org>
+
+ Rewrite library option handling in `configure'.
+
+ o Introduce `auto' value for `--with-XXX' library options; this is
+ now the default.
+
+ o First use `pkg-config' for library detection, then fall back to
+ other tests.
+
+ * builds/unix/configure.raw (--with-zlib, --with-bzip2, --with-png,
+ --with-harfbuzz): Rewrite.
+ Use new `xxx_reqpriv', `xxx_libpriv', and `xxx_libstaticconf'
+ variables to collect data for `freetype2.pc' and `freetype-config'.
+ (FT2_EXTRA_LIBS): Renamed to ...
+ (ft2_extra_libs): This since it gets no longer substituted.

+ New output variables, replacing `XXX_PKG' and `LIBXXX'.
+ Add notice at the end of `configure' showing the library
+ configuration.

+
+2014-03-01 Werner Lemberg <wl@gnu.org>
+
+ Avoid `long long' warnings with older gcc compilers.
+ Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>.
+
+ * builds/unix/configure.raw: Don't use gcc's `-pedantic' flag for
+ versions < 4.6. This is especially needed for Max OS X since this
+ OS runs a gcc variant (or emulation) based on version 4.2.1.
+
+2014-03-01 Werner Lemberg <wl@gnu.org>
+
+ * docs/INSTALL.CROSS: Revised and updated.
+
+2014-03-01 Werner Lemberg <wl@gnu.org>
+
+ Make `make clean' remove `freetype2.pc'.
+
+ This is a generated file at build time, not configure time.
+
+ * builds/unix/unix-def.in (DISTCLEAN): Move `freetype2.pc' to ...
+ (CLEAN): This variable.
+
+2014-03-01 Werner Lemberg <wl@gnu.org>
+
+ Use pkg-config for detecting libpng and libbz2 also.
+
+ * builds/unix/configure.raw (HAVE_PKG): New variable.
+ Search for libbz2 using `pkg-config'; s/BZ2/BZIP2/.
+ Search for libpng using `pkg-config'.
+ Fix definition of `LIBHARFBUZZ' variable.
+ * builds/unix/freetype-config.in ($libs): Updated.
+ * builds/unix/freetype2.in: Add `URL' field.

+
+2014-03-01 Werner Lemberg <wl@gnu.org>
+
+ Add configure support for HarfBuzz.
+
+ * builds/unix/pkg.m4: New file.
+ * builds/unix/configure.raw: Search for libharfbuzz using
+ `pkg-config'.
+ Add `--without-harfbuzz' option.
+ * builds/unix/freetype-config.in, builds/unix/freetype2.in,
+ builds/unix/unix-def.in (freetype-config, freetype2.pc): Handle
+ HarfBuzz.
+
+ * docs/INSTALL.UNIX: Document interdependency of Freetype with
+ HarfBuzz.
+
+2014-02-28 Alexei Podtelezhnikov <apodtele@gmail.com>
+
+ [cff] Math simplifications.
+
+ * src/cf2blues.c (cf2_blues_init): Use `FT_MulDiv'.
+ * src/cf2ft.c (cf2_getScaleAndHintFlag): Use simple division.
+
+2014-02-28 Dave Arnold <darnold@adobe.com>
+
+ [cff] Fix Savannah bug #41697, part 2.
+
+ * 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.
+
+2014-02-28 Dave Arnold <darnold@adobe.com>
+
+ [cff] Fix Savannah bug #41697, part 1.
+
+ * src/cff/cf2hints.c (cf2_hintmap_build): Return when `hintMask' is
+ invalid. In this case, it is not safe to use the length of
+ `hStemHintArray'; the exception has already been recorded in
+ `hintMask'.
+
+2014-02-26 Werner Lemberg <wl@gnu.org>
+
+ [sfnt] Fix Savannah bug #41696.
+
+ * src/sfnt/ttcmap.c (tt_cmap0_validate, tt_cmap2_validate,
+ tt_cmap4_validate, tt_cmap14_validate): Fix limit tests.
+
+2014-02-26 Werner Lemberg <wl@gnu.org>
+
+ [winfnt] Fix Savannah bug #41694.

+
+2014-02-26 Werner Lemberg <wl@gnu.org>
+
+ [cff] Fix Savannah bug #41693.
+
+ * src/cff/cffload.c (CFF_Load_FD_Select): Reject empty array.
+
+2014-02-26 Werner Lemberg <wl@gnu.org>
+
+ [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.
+
+2014-02-17 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
+
+ [autofit] Fix `make multi' compilation.
+
+ * src/autofit/hbshim.c: Include `afglobal.h' and `aftypes.h'.
+
+2014-02-19 Werner Lemberg <wl@gnu.org>
+ Simon Bünzli <zeniko@gmail.com>
+

+
+ with slight modifications.
+
+ * src/type1/t1parse.c (T1_Get_Private_Dict): Add heuristic test to
+ handle fonts that incorrectly use \r at the beginning of an eexec
+ block.
+
+2014-02-19 Simon Bünzli <zeniko@gmail.com>
+
+ Fix Savannah bug #41590.
+
+ * src/type1/t1load.c (parse_encoding): Protect against invalid
+ number.
+
+2014-02-12 Dave Arnold <darnold@adobe.com>

+
+ * src/autofit/afhints.c (af_glyph_hints_align_weak_points),

+ `windows'.
+
+ * builds/windows/detect.mk, builds/windows/win32-def.mk:

+
+2014-02-08 Dave Arnold <darnold@adobe.com>
+
+ [cff] Fix minor performance bug.
+
+ * src/cff/cf2font.c (cf2_font_setup): Darkening amount and blue zone
+ calculations are now cached and not recomputed on each glyph.
+
+2014-02-05 Werner Lemberg <wl@gnu.org>
+
+ Fix problems with perl 5.8.8 as distributed with current MinGW.
+
+ * src/tools/afblue.pl: Work-around for Perl bug #63402.
+ (string_re): Avoid `possessive quantifiers', which have been
+ introduced in Perl version 5.10.
+
+2014-02-04 Werner Lemberg <wl@gnu.org>
+
+ Fix compilation with MinGW.
+
+ Right now, compilation out of the box with latest MinGW is broken

+
+2014-01-26 Werner Lemberg <wl@gnu.org>
+
+ [autofit] Introduce two more slots for standard characters.

+
+ Fix Savannah bug #41310.
+
+ * src/sfnt/ttsbit.c (tt_sbit_decoder_load_bitmap) <glyph_format==5>:

+ [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.
+
+2014-01-03 Werner Lemberg <wl@gnu.org>
+
+ [autofit] Thinko.
+
+ * src/autofit/hbshim.c (af_get_char_index): Similar to
+ `af_get_coverage', reject glyphs which are not substituted.
+
+2014-01-03 Werner Lemberg <wl@gnu.org>
+
+ [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
+ do.
+ Reject coverages which don't contain appropriate glyphs for blue
+ zones.
+
+2014-01-03 Werner Lemberg <wl@gnu.org>
+
+ [autofit] Fix handling of default coverages.
+
+ * src/autofit/afglobal.c (af_face_globals_compute_style_coverage):
+ First handle non-default coverages, then the default coverage of the
+ default script, and finally the other default coverages.
+
+2014-01-03 Werner Lemberg <wl@gnu.org>
+
+ [autofit] Fix scaling of HarfBuzz shaping.
+
+ * src/autofit/hbshim.c (af_get_char_index): Scale to units per EM.

+2014-01-01 Werner Lemberg <wl@gnu.org>
+
+ [autofit] Add more styles.
+
+ * src/autofit/afstyles.h (STYLE_LATIN, META_STYLE_LATIN): New
+ auxiliary macros; use them to define styles for Cyrillic, Greek, and
+ Latin.
+
+ * 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.
+
+ * src/autofit/afglobal.c (af_face_globals_get_metrics): Don't limit
+ `options' parameter to 4 bits.
+
+2014-01-01 Werner Lemberg <wl@gnu.org>
+
+ [autofit] Fix style assignments to glyphs.
+
+ * src/autofit/hbshim.c (af_get_coverage)
+ [FT_CONFIG_OPTION_USE_HARFBUZZ]: Scan GPOS coverage of features also
+ so that we can skip glyphs that have both GSUB and GPOS data.

+2014-01-01 Werner Lemberg <wl@gnu.org>
+
+ * src/autofit/hbshim.c: s/{lookups,glyphs}/gsub_{lookups,glyphs}/.

+
+ [autofit] Implement and use `af_get_char_index' with HarfBuzz.
+
+ * src/autofit/hbshim.c (COVERAGE) [FT_CONFIG_OPTION_USE_HARFBUZZ]:

+
+ * src/autofit/aflatin.c (af_latin_metrics_init_blues): Use
+ `y_offset' to adjust `best_y'.

+ * src/autofit/hbshim.c (af_get_char_index): Return error value.
+ Add argument for y offset (to be used in a yet-to-come patch).

+
+2013-12-30 Werner Lemberg <wl@gnu.org>
+
+ [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.
+
+ * src/autofit/afcover.h: Replace `COVERAGE_{1,2,3}' macros with

+ [autofit] Use `global' HarfBuzz font object.
+
+ We now use `hb_font' instead of `hb_face' since yet-to-come changes
+ need this.

+
+ [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 FreeType 2
+ without Carbon framework.) Found by Khaled Hosny and Hin-Tak Leung.

+
+2013-12-21 Werner Lemberg <wl@gnu.org>
+
+ [autofit] Introduce `coverages'.
+
+ Coverages are the interface to the HarfBuzz library to acces
+ 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

+ Simplify header file hierarchy.
+
+ This large patch changes the header file directory layout from

+ 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

+
+ * src/cff/cf2font.c (cf2_computeDarkening): Avoid division by zero.

+ incorrect amount of darkening.

+
+ * src/cff/cf2font.c (cf2_computeDarkening): Initialize darkenAmount.
+
+ This line was lost in commit 89ca1fd6 (from 2013-06-25). The effect
+ is to use a previous darkening amount when producing an unhinted,
+ unscaled outline. This can cause autohint samples in ftgrid and
+ ftview to be based on darkened CFF outlines instead of unhinted,
+ undarkened ones.
+
+2013-09-29 Dave Arnold <darnold@adobe.com>
+
+ Fix Savannah bug #39295.
+
+ The bug was caused by switching to the initial hintmap (the one in
+ effect when `moveto' executes) just before drawing the final element
+ in the charstring. This ensured that the path was closed (in both
+ Character Space and Device Space). But if the final element was a
+ curve and if the final hintmap was different enough from the initial
+ one, then the curve was visibly distorted.
+
+ The first part of the fix is to draw the final curve using the final
+ hintmap as specified by the charstring. This corrects the
+ distortion but does not ensure closing in Device Space. It may
+ require the rasterizer to automatically generate an extra closing
+ line. Depending on the hintmap differences, this line could be from
+ zero to a couple pixels in length.
+
+ The second part of the fix covers the case where the charstring
+ subpath is closed with an explicit line. We now modify that line's
+ end point to avoid the distortion.
+
+ Some glyphs in the bug report font (TexGyreHeros-Regular) that show
+ the change are:
+
+ 25ppem S (98)
+ 24ppem eight (52)
+ 25.5ppem p (85)
+
+ Curves at the *end* of a subpath are no longer distorted. However,
+ some of these glyphs have bad hint substitutions in the middle of a
+ subpath, and these are not affected.
+
+ The patch has been tested with a set of 106 fonts that shipped with
+ Adobe Creative Suite 4, together with 756 Open Source CFF fonts from
+ Google Fonts. There are 1.5 million glyphs, of which some 20k are
+ changed with the fix. A sampling of a few hundred of these changes
+ have been examined more closely, and the changes look good (or at
+ least acceptable).
+
+ * src/cff/cf2hints.h (CF2_GlyphPathRec): New element `pathIsClosing'
+ to indicate that we synthesize a closepath line.
+
+ * src/cff/cf2hints.c (cf2_glyphpath_init): Updated.
+ (cf2_glyphpath_pushPrevElem): If closing, use first hint map (for
+ `lineto' operator) and adjust hint zone.
+ For synthesized closing lines, use end point in first hint zone.
+ (cf2_glyphpath_lineTo): Take care of synthesized closing lines. In
+ particular, shift the detection of zero-length lines from character
+ space to device space.
+ (cf2_glyphpath_closeOpenPath): Remove assertion.
+ Updated.

+
+ [autofit] Introduce data file for blue strings.
+
+ The idea is to have a central file which gets processed by a Perl
+ script to create proper `.c' and `.h' files using templates. There
+ are two other reasons to do that:
+
+ . The data file should be easily readable. We use UTF-8 encoding
+ which then gets converted to single bytes.
+
+ . Since the number of supported scripts will increase soon, the
+ current usage of blue string arrays is a waste of space. Using
+ the Perl script it is possible to imitate jagged arrays,
+ defining enumeration constants as offsets into the arrays.
+
+ This commit only adds files without changing any functionality.
+
+ * src/autofit/afblue.dat: New data file.

+
+ Speed up ARMv7 support.
+
+ When building for ARMv7 with thumb2 instructions, the optimized
+ `FT_MulFix_arm' assembly routine was not being used.
+
+ The reason for this is in the `ftconfig.h' header, namely:
+
+ - The assembly routine uses the `smull' instruction which is not
+ available when generating Thumb-1 machine code. It is available
+ in Thumb-2 mode, though.
+
+ - The header was written a long time ago before Thumb-2 became
+ widely popular (e.g. with Android). So it simply doesn't use the
+ assembly routine if the `__thumb__' built-in macro is defined.
+
+ - When compiling in Thumb-2 mode, the compiler will define both
+ `__thumb__' and `__thumb2__'.
+
+ By checking for `(__thumb2__ || !__thumb__)', we ensure that the
+ assembly routine is only avoided when generating Thumb-1 code.
+
+ Given that this is performance-sensitive function, this improves
+ `ftbench' as follows on a Galaxy Nexus:
+
+ Before (us/op) After (us/op)
+
