 	Reported in https://bugs.freedesktop.org/show_bug.cgi?id=75652.

 	* 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>

 	Fix several clang static analyzer dead store warnings.

 	* src/autofit/afhints.c (af_glyph_hints_reload,

 	af_glyph_hints_align_weak_points): Remove unnecessary assignments.

 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.

 	(REQUIRES_PRIVATE, LIBS_PRIVATE, LIBS_CONFIG, LIBSSTATIC_CONFIG):

 	New output variables, replacing `XXX_PKG' and `LIBXXX'.

 	Add notice at the end of `configure' showing the library

 	configuration.

 	* builds/unix/freetype-config.in (--static): New command line

 	option.

 	(libs): Updated.

 	(staticlibs): New variable, to be used if `--static' is given.

 	* builds/doc/freetype-config.1: Document `--static'.

 	* builds/unix/freetype2.in, builds/unix/unix-def.in: Updated.

 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.

 	Update `Requires.private' and `Libs.private'.

 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.

 	* src/winfonts/winfnt.c (FNT_Load_Glyph): Check glyph offset.

 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>

 	Fix Savannah bug #32902.

 	Patch taken from

 	  https://code.google.com/p/sumatrapdf/source/browse/trunk/ext/_patches/freetype2.patch?spec=svn8620&r=8620#87

 	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.

 	number.

 2014-02-12  Dave Arnold  <darnold@adobe.com>

 	Suggested by Alexei.

 	* src/cff/cf2font.c (cf2_computeDarkening): Do it.

 2014-02-12  Werner Lemberg  <wl@gnu.org>

 	Fix Savannah bug #41465.

 	* builds/unix/unix-def.in (CLEAN): Add `freetype-config'.

 	* builds/modules.mk: Don't use `win32' and `win16' (!) but

 	`windows'.

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

 	[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.

 	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

 	due to bugs in header files of mingwrt 4.0.3 in strict ANSI mode,

 	cf.

 	  https://sourceforge.net/p/mingw/bugs/2024/

 	  https://sourceforge.net/p/mingw/bugs/2046/

 	* src/cff/cf2ft.c (cf2_checkTransform): Convert assertion into

 	parameter check.

 	(cf2_decoder_parse_charstrings): Call `cf2_checkTransform' only if

 	we are scaling the outline.

 	(cf2_getPpemY): Remove problematic assertion.

 2014-01-26  Werner Lemberg  <wl@gnu.org>

 	[autofit] Introduce two more slots for standard characters.

 	This is useful for OpenType features like `c2sc' (caps to small

 	caps) that don't have lowercase letters by definition, or other

 	features that mainly operate on numerals.

 	* src/autofit/afscript.h: Add more standard characters.

 2014-01-23  Werner Lemberg  <wl@gnu.org>

 	Fix Savannah bug #41309.

 	* src/type1/t1load.c (t1_parse_font_matrix): Properly handle result

 	of `T1_ToFixedArray'.

 	* src/cid/cidload.c (cid_parse_font_matrix): Synchronize with

 	`t1_parse_font_matrix'.

 2014-01-08  Werner Lemberg  <wl@gnu.org>

 	[autofit] Fix Savannah bug #41138, part 1.

 	* src/tools/afblue.pl <Handling #endif>: Produce correct auxiliary

 	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.

 2014-01-03  Werner Lemberg  <wl@gnu.org>

 	[autofit] Better ftgrid support.

 	* src/autofit/afhints.c (af_glyph_hints_get_segment_offset): Add

 	parameters `is_blue' and `blue_offset'.

 2014-01-01  Werner Lemberg  <wl@gnu.org>

 	[autofit] Remove some styles.

 	* src/autofit/afcover.h: Remove coverages for alternative fractions,

 	denominators, numerators, and fractions.

 	* src/autofit/afstyles.h (META_STYLE_LATIN): Updated.

 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}/.

 2014-01-01  Werner Lemberg  <wl@gnu.org>

 	[autofit] Implement and use `af_get_char_index' with HarfBuzz.

 	* src/autofit/hbshim.c (COVERAGE) [FT_CONFIG_OPTION_USE_HARFBUZZ]:

 	Redefine to construct HarfBuzz features.

 	(af_get_char_index) [FT_CONFIG_OPTION_USE_HARFBUZZ]: Rewritten.

 	* src/autofit/aflatin.c (af_latin_metrics_init_blues): Use

 	`y_offset' to adjust `best_y'.

 2013-12-31  Werner Lemberg  <wl@gnu.org>

 	[autofit] s/AF_STYLE_...._DEFAULT/AF_STYLE_...._DFLT/i.

 2013-12-31  Werner Lemberg  <wl@gnu.org>

 	[autofit] Fix interface of `af_get_char_index'.

 	* 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).

 	* src/autofit/hbshim.h, src/autofit/afcjk.c,

 	src/autofit/aflatin.c: Updated.

 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

 	a single-element `COVERAGE' macro, sort the elements by the feature

 	tags, and add entry for `ruby'.

 	* src/autofit/aftypes.h: Updated.

 	* src/autofit/hbshim.c: Updated.

 2013-12-28  Werner Lemberg  <wl@gnu.org>

 	[autofit] Code shuffling to reduce use of cpp macros.

 	* src/autofit/afglobal.c (af_face_globals_compute_style_coverage):

 	[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

 	(autofit_module_class_pic_init): Typo.

 	* src/autofit/aftypes.h (AF_DEFINE_SCRIPT_CLASS,

 	parameter and structure member.

 2013-12-20  Werner Lemberg  <wl@gnu.org>

 	[sfnt] Fix `OS/2' table version 5 support.

 	We now follow the `official' announcement from Microsoft (on the

 	OpenType mailing list, which unfortunately hasn't a public archive).

 	* include/freetype/tttables.h (TT_OS2):

 	s/usLowerPointSize/usLowerOpticalPointSize/,

 	s/usUpperPointSize/usUpperOpticalPointSize/.

 	* src/sfnt/ttload.c (tt_face_load_os2): Update, and set correct

 	default values.

 2013-11-13  Werner Lemberg  <wl@gnu.org>

 	* builds/unix/ft2unix.h: Remove.  No longer necessary.

 	* builds/unix/install.mk (install): Updated.

 2013-11-13  Werner Lemberg  <wl@gnu.org>

 	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.

 2013-11-01  Werner Lemberg  <wl@gnu.org>

 	* docs/CHANGES: Updated.

 2013-11-01  Werner Lemberg  <wl@gnu.org>

 	[truetype] Minor code refactoring.

 	Two benefits: The allocated FDEF (and IDEF) array gets slightly

 	smaller, and the `ttdebug' demo program has access to function

 	numbers without additional costs.

 	Fortunately, no changes to FontForge are necessary – this is the

 	only external TrueType debugger I know of, but others may exist and

 	should check the code accordingly.

 	* src/truetype/ttinterp.h (TT_CallRec): Replace `Cur_Restart' and

 	`Cur_End' with a pointer to the corresponding `TT_DefRecord'

 	structure.

 	* src/truetype/ttinterp.c (DO_JROT, DO_JMPR, DO_JROF, Ins_ENDF,

 	Ins_CALL, Ins_LOOPCALL, Ins_UNKNOWN, TT_RunIns <Invalid_Opcode>):

 	Updated.

 	[sfnt] Implement support for `OS/2' table version 5.

 	See

 	  http://typedrawers.com/discussion/470/new-microsoft-size-specific-design-selection-mechanism

 	for the announcement.

 	* include/freetype/tttables.h (TT_OS2): Add fields

 	`usLowerPointSize' and `usUpperPointSize'.  Since FreeType returns

 	this structure only as a pointer through `FT_Get_Sfnt_Table', there

 	shouldn't be any ABI problems.

 	* src/sfnt/ttload.c (tt_face_load_os2): Implement it.

 	* docs/CHANGES: Updated.

 2013-10-24  Werner Lemberg  <wl@gnu.org>

 	* src/builds/windows: This.

 	* src/builds/windows/vc2010/*: Updated to handle x64 target.

 	* src/builds/windows/*.mk, docs/INSTALL.GNU: s/win32/windows/ where

 	appropriate.

 2013-10-22  Werner Lemberg  <wl@gnu.org>

 	* src/base/md5.c, src/base/md5.h: Updated to recent version.

 	* src/autofit/aflatin.c (af_latin_metrics_scale_dim): Do it.

 2013-10-15  Chongyu Zhu  <lembacon@gmail.com>

 	[arm] Fix thumb2 inline assembly under LLVM.

 	When using `ADD' with an immediate operand, the instruction is

 	actually `ADD Rd, Rn, #<imm12>', that is, the maximum of the

 	immediate operand cannot exceed 4095.  It will fail to compile with

 	LLVM.

 	However, in GCC, due to some legacy compatibility considerations,

 	`ADD.W' will be automatically emitted when the immediate operand is

 	larger than 4095.

 	* builds/unix/ftconfig.in, include/freetype/config/ftconfig.h

 	(FT_MulFix_arm) [__GNUC__]: Support clang compiler.

 	* src/truetype/ttinterp.c (TT_MulFix14_arm) [__GNUC__]: Ditto.

 	* src/autofit/aflatin.c (af_latin_metrics_init_blues): Report blue

 	zone types.

 	(af_latin_metrics_scale_dim): Report scaling changes due to x height

 	alignment.

 	Report scaled stroke width and blue zone values.

 2013-10-03  Dave Arnold  <darnold@adobe.com>

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

 	Note that the old code avoided using a region of the piecewise

 	linear function where the slope was zero.  The recovery was to use a

 	different section of the function, which produced a different,

 	incorrect amount of darkening.

 2013-10-02  Darrell Bellert  <darrell.bellert@hl.konicaminolta.us>

 	* src/sfnt/ttload.c (tt_face_load_pclt): Fix `pclt_fields'.

 2013-10-02  Dave Arnold  <darnold@adobe.com>

 	* 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.

             Behdad Esfahbod  <behdad@google.com>

 	Implement support for WOFF containers.

 	FT_Open_Face: Improve external stream handling.

 	If the font's `clazz->init_face' function wants to swap to new

 	Better tracing of loaded glyphs.

 	Previously, the loading of a glyph was traced at level 4, if at all.

 	With this change, all font loading routines emit a tracing message

 	Change loops to use offsets (in file `afblue.h') into the new arrays

 	`af_blue_stringsets' and `af_blue_strings' (in file `afblue.c').

 	Instead of three dimensions (as used in the old blue string array)

 	we now use properties to do the same, saving one loop nesting level.

 2013-08-25  Werner Lemberg  <wl@gnu.org>

 	[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.

 	* src/tools/afblue.pl: New Perl script for processing `afblue.dat'.

 	* src/autofit/afblue.cin, src/autofit/afblue.hin: New template files

 	for...

 	* src/autofit/afblue.c, src/autofit/afblue.c: New source files.

 	[autofit] Improve handling of `near' points.

 	Points which are very near to each other are now marked as such.

 	The `weak' flag is then computed by using the `in' vector of the

 	points.

 	For example, this fixes the rendering of glyph `Oslash' in

 	`Roboto-Thin.ttf'.

 	is near to the previous one, then set `AF_FLAG_NEAR' accordingly.

 	Store good `in' vector (of last non-near point) in

 	`last_good_in_{x,y}' and use it as an argument to

 	`ft_corner_is_flat' if necessary.

 2013-07-30  Werner Lemberg  <wl@gnu.org>

 	[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

 	              o---------------o

 	as round.  (`o' and `x' are on and off points, respectively).

 	This is a major change which should improve the rendering results

 	(FT_MulFix_x86_64): New function.

 2013-07-16  David Turner  <digit@google.com>

 	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:
