-	[otvalid] Fix a naming convention conflicting with ftvalid.

-	Some prototypes in ftvalid.h use `valid' for the variables

-	typed as FT_Validator.  Their implementations in src/base/

-	ftobjs.c and utilizations in src/sfnt/ttcmap.c do similar.

-	Some macros in otvcommn.h assume the exist of the variable

-	`valid' typed as OTV_Validator in the caller.

-	Mixing these two conventions cause invalid pointer conversion

-	and unexpected SEGV in longjmp.  To prevent it, all variables

-	typed as OTV_Validator are renamed to `otvalid'.

-	* src/cff/cf2hints.c (cf2_hintmap_map): After the fix for Savannah

-	[autofit] Better fix for conversion specifiers in debug messages.

-	Using `%ld' for pointer differences causes warnings on 32bit

-	platforms.  The correct type would be (the relatively new) `%td',

-	however, this is missing on some important platforms.

-	This patch improves the change from 2014-11-28.

-	* src/autofit/afhints.c (AF_INDEX_NUM): Use `int' typecast.  Our

-	pointer differences are always sufficiently small.

-	af_glyph_hints_dump_edge): Revert to `%d' and use `AF_INDEX_NUM'.

-	[docmaker] Allow empty lines in `<Order>' blocks.

-	Before this patch, the suggested order of entries stopped at the

-	first empty line.

-	Obviously, nobody noticed that this problem caused a much reduced

-	set of links in the `Synopsis' sections; in particular, the

-	[cff, pfr, psaux, winfonts] Fix Savannah bug #43676.

-	Don't cast cmap init function pointers to an incompatible type.

-	Without this patch, the number of parameters between declaration and

-	the real signature differs.  Calling such a function results in

-	undefined behavior.

-	  ISO/IEC 9899:TC3 (Committee Draft September 7, 2007)

-	    6.5.2.2 Function calls

-	      9 If the function is defined with a type that is not

-	        compatible with the type (of the expression) pointed to by

-	        the expression that denotes the called function, the

-	        behavior is undefined.

-	On certain platforms (c -> js with emscripten) this causes

-	termination of execution or invalid calls because in the emscripten

-	implementation, function pointers of different types are stored in

-	different pointer arrays.  Incorrect pointer type here results in

-	indexing of an incorrect array.

-	Avoid compiler warnings on x86-64 for `FT_MulFix'.

-	`FT_MulFix' takes `FT_Long' parameters as defined in `freetype.h',

-	but several inline implementations of it in `ftcalc.h' take

-	* src/truetype/ttinterp.c (Ins_DELTAP): Fix subpixel hinting.

-	Before this patch, it was impossible to ever call DELTAP[123] in

-	subpixel hinting mode as described in the ClearType whitepaper; it

-	only worked if in `compatibility mode'.  However, compatibility mode

-	essentially disables SHPIX, completely ruining hinting of

-	[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.

-2014-04-17  Werner Lemberg  <[email protected]>

-	[autofit] More coverage fixes for complex scripts.

-	* src/autofit/hbshim.c (af_get_coverage): Merge input glyph coverage

-	of GSUB lookups into output coverage.  Otherwise, ligatures are not

-	Don't check blue zone characters for default coverage.

-2014-04-17  Werner Lemberg  <[email protected]>

-2014-04-12  Werner Lemberg  <[email protected]>

-	[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'.

-2014-04-05  Werner Lemberg  <[email protected]>

-	[autofit] Improve scoring algorithm for identifying stems.

-	Problem reported by Karsten Lücke <[email protected]>.

-	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

-2014-03-04  Werner Lemberg  <[email protected]>

-	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

-2014-03-03  Werner Lemberg  <[email protected]>

-	Rewrite library option handling in `configure'.

-	  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'

-	Problem reported by Hin-Tak Leung <[email protected]>.

-	* builds/unix/configure.raw: Don't use gcc's `-pedantic' flag for

-	* docs/INSTALL.CROSS: Revised and updated.

-2014-03-01  Werner Lemberg  <[email protected]>

-	* src/cf2ft.c (cf2_getScaleAndHintFlag): Use simple division.

-2014-02-28  Dave Arnold  <[email protected]>

-	[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  <[email protected]>

-	[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  <[email protected]>

-	[sfnt] Fix Savannah bug #41696.

-	* src/sfnt/ttcmap.c (tt_cmap0_validate, tt_cmap2_validate,

-	* src/cff/cffload.c (CFF_Load_FD_Select): Reject empty array.

-2014-02-26  Werner Lemberg  <[email protected]>

-	[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  <[email protected]>

-	[autofit] Fix `make multi' compilation.

-	* src/autofit/hbshim.c: Include `afglobal.h' and `aftypes.h'.

-2014-01-26  Werner Lemberg  <[email protected]>

-	[autofit] Introduce two more slots for standard characters.

-	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.

-2014-01-03  Werner Lemberg  <[email protected]>

-	[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  <[email protected]>

-	[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  <[email protected]>

-	[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  <[email protected]>

-	[autofit] Fix scaling of HarfBuzz shaping.

-	* src/autofit/hbshim.c (af_get_char_index): Scale to units per EM.

-2014-01-03  Werner Lemberg  <[email protected]>

-	[autofit] Better ftgrid support.

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

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

-	denominators, numerators, and fractions.

-2014-01-01  Werner Lemberg  <[email protected]>

-	[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  <[email protected]>

-	[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  <[email protected]>

-	* src/autofit/hbshim.c: s/{lookups,glyphs}/gsub_{lookups,glyphs}/.

-2014-01-01  Werner Lemberg  <[email protected]>

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

-	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  <[email protected]>

-	[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

-	[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.

-	[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

-	[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

-2013-11-13  Werner Lemberg  <[email protected]>

-	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.

-	* docs/CHANGES: Updated.

-2013-11-01  Werner Lemberg  <[email protected]>

-	[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.

-	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.

-2013-10-15  Chongyu Zhu  <[email protected]>

-	[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.

-	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  <[email protected]>

-	* 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  <[email protected]>

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

-2013-10-02  Dave Arnold  <[email protected]>

-	* 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  <[email protected]>

-	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.

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

-	(FT_MulFix_x86_64): New function.

-2013-07-16  David Turner  <[email protected]>

-	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)

+2014-12-11  Werner Lemberg  <[email protected]>

+	* builds/toplevel.mk (dist): Use older POSIX standard for `tar'.

+	Apparently, BSD tar isn't capable yet of handling POSIX-1.2001

+	(contrary to GNU tar), so force the POSIX-1.1988 format.

+	Problem reported by Stephen Fisher <[email protected]>.

+2014-12-11  Werner Lemberg  <[email protected]>

+	[gxvalid] Fix a naming convention conflicting with ftvalid.

+	See previous changeset for otvalid.

+	* src/gxvalid/{gxvcommn.h, gxvmort.h, gxvmorx.h}: Replace

+	`valid' by `gxvalid'.

+	* src/gxvalid/{gxvbsln.c, gxvcommn.c, gxvfeat.c, gxvjust.c,

+	gxvkern.c, gxvlcar.c, gxvmort.c, gxvmort0.c, gxvmort1.c,

+	gxvmorx1.c, gxvmorx2.c, gxvmorx4.c, gxvmorx5.c, gxvopbd.c,

+	gxvprop.c, gxvtrak.c}: Replace `valid' by `gxvalid' if

+	it is typed as GXV_Validator.

+2014-12-09  suzuki toshiya  <[email protected]>

+	[otvalid] Fix a naming convention conflicting with ftvalid.

+	Some prototypes in ftvalid.h use `valid' for the variables

+	typed as FT_Validator.  Their implementations in src/base/

+	ftobjs.c and utilizations in src/sfnt/ttcmap.c do similar.

+	Some macros in otvcommn.h assume the exist of the variable

+	`valid' typed as OTV_Validator in the caller.

+	Mixing these two conventions cause invalid pointer conversion

+	and unexpected SEGV in longjmp.  To prevent it, all variables

+	typed as OTV_Validator are renamed to `otvalid'.

+	* src/otvalid/otvcommn.h: Replace `valid' by `otvalid'.

+	* src/otvalid/{otvcommn.c, otvbase.c, otvgdef.c, otvgpos.c,

+	otvgsub.c, otvjstf.c, otvmath.c}: Replace `valid' by `otvalid'

+	if it is typed as OTV_Validator.

+2014-12-09  suzuki toshiya  <[email protected]>

+	[ftvalid] Introduce FT_THROW() in FT_INVALID_XXX macros.

+	Original patch is designed by Werner Lemberg.  Extra part

+	for otvalid and gxvalid are added by suzuki toshiya, see

+	discussion:

+	http://lists.nongnu.org/archive/html/freetype-devel/2014-12/msg00002.html

+	http://lists.nongnu.org/archive/html/freetype-devel/2014-12/msg00007.html

+	* src/gxvalid/gxvcommn.h: Ditto.

+	* src/otvalid/otvcommn.h: Ditto.

+2014-12-08  Werner Lemberg  <[email protected]>

+	[pcf] Fix Savannah bug #43774.

+	Work around `features' of X11's `pcfWriteFont' and `pcfReadFont'

+	functions.  Since the PCF format doesn't have an official

+	specification, we have to exactly follow these functions' behaviour.

+	The problem was unveiled with a patch from 2014-11-06, fixing issue

+	#43547.

+	* src/pcf/pcfread.c (pcf_read_TOC): Don't check table size for last

+	element.  Instead, assign real size.

+2014-12-07  Werner Lemberg  <[email protected]>

+	Work around a bug in Borland's C++ compiler.

+	See

+	  http://qc.embarcadero.com/wc/qcmain.aspx?d=118998

+	for Borland's bug tracker entry.

+	Reported by Yuliana Zigangirova <[email protected]>,

+	http://lists.gnu.org/archive/html/freetype-devel/2014-04/msg00001.html.

+	* include/internal/ftvalid.h (FT_ValidatorRec), src/smooth/ftgrays.c

+	(gray_TWorker_): Move `ft_jmp_buf' field to be the first element.

+2014-12-07  Werner Lemberg  <[email protected]>

+	docs/CHANGES: Updated, formatted.

+2014-12-04  Dave Arnold  <[email protected]>

+	[cff] Modify an FT_ASSERT.

+	* src/cff/cf2hints.c (cf2_hintmap_map): After the fix for Savannah

+	bug #43661, the test font `...aspartam.otf' still triggers an

+	FT_ASSERT.  Since hintmap still works with count==0, ...

+	(cf2_glyphpath_lineTo, cf2_glyphpath_curveTo): ... add that term to

+	suppress the assert.

+2014-12-04  Dave Arnold  <[email protected]>

+	docs/CHANGES: Updated.

+2014-12-03  Werner Lemberg  <[email protected]>

+	[autofit] Better fix for conversion specifiers in debug messages.

+	Using `%ld' for pointer differences causes warnings on 32bit

+	platforms.  The correct type would be (the relatively new) `%td',

+	however, this is missing on some important platforms.

+	This patch improves the change from 2014-11-28.

+	* src/autofit/afhints.c (AF_INDEX_NUM): Use `int' typecast.  Our

+	pointer differences are always sufficiently small.

+	(af_glyph_hints_dump_points, af_glyph_hints_dump_segments,

+	af_glyph_hints_dump_edge): Revert to `%d' and use `AF_INDEX_NUM'.

+2014-12-03  Werner Lemberg  <[email protected]>

+	FT_Sfnt_Tag: s/ft_sfnt_xxx/FT_SFNT_XXX/ for orthogonality.

+	All public FreeType enumeration and flag values are uppercase...

+	* include/tttables.h (FT_Sfnt_Tag): Implement it.  For backwards

+	compatilibity, retain the old values as macros.

+	* src/base/ftfstype.c (FT_Get_FSType_Flags), src/sfnt/sfdriver.c

+	(get_sfnt_table): Updated.

+2014-12-02  Werner Lemberg  <[email protected]>

+	* include/*: Improve structure of documentation.

+	. Add and update many `<Order>' tags.

+	. Apply various documentation fixes.

+	. Remove details to deprecated (or never implemented) data.

+2014-12-02  Werner Lemberg  <[email protected]>

+	[docmaker] Always handle `<Order>' section elements.

+	Previously, those elements were handled only for sections present in

+	a `<Sections>' chapter element.

+	* src/tools/docmaker/content.py (ContentProcessor::finish):

+	Implement it.

+2014-12-02  Werner Lemberg  <[email protected]>

+	[docmaker] Properly handle empty rows in Synopsis.

+	* src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Emit

+	`&nbsp;' for empty fields.

+2014-12-02  Werner Lemberg  <[email protected]>

+	[docmaker] Thinko.

+	* src/tools/docmaker/content.py (DocBlock::get_markup_words_all):

+	Emit `/empty/' string for first element also.

+2014-12-02  Werner Lemberg  <[email protected]>

+	[docmaker] Honour empty lines in `<Order>' section element.

+	This greatly improves the readability of the `Synopsis' links.

+	* src/tools/docmaker/content.py (DocBlock::get_markup_words_all):

+	Insert string `/empty/' between items.

+	* src/tools/docmaker/formatter.py (Formatter::section_dump): Make it

+	robust against nonexistent keys.

+	* src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Emit

+	empty <td> elements for `/empty/'.

+2014-12-02  Werner Lemberg  <[email protected]>

+	[docmaker] Ensure Python 3 compatibility.

+	* src/tools/docmaker/content.py (ContentProcessor::set_section,

+	ContentProcessor::finish): Replace `has_key' function with `in'

+	keyword.

+	* src/tools/docmaker/formatter.py (Formatter::__init__): Replace

+	sorting function with a key generator.

+	(Formatter::add_identifier): Replace `has_key' function with `in'

+	keyword.

+	* src/tools/docmaker/tohtml.py (HtmlFormatter::html_source_quote):

+	Replace `has_key' function with `in' keyword.

+	(HtmlFormatter::index_exit, HtmlFormatter::section_enter): Use

+	integer division.

+	s/<>/>/.

+	* src/tools/docmaker/utils.py: Import `itertools'.

+	(index_sort): Replaced by...

+	(index_key): ... this new key generator (doing exactly the same).

+2014-11-29  Werner Lemberg  <[email protected]>

+	[docmaker] Don't output a block multiple times.

+	This bug was hidden by not processing all lines of `<Order>' blocks.

+	* src/tools/docmaker/formatter.py (Formatter::section_dump): Filter

+	out field names.

+2014-11-29  Werner Lemberg  <[email protected]>

+	[docmaker] Use field values as HTML link targets where possible.

+	* src/tools/docmaker/tohtml.py (HtmlFormatter::make_block_url):

+	Accept second, optional argument to specify a name.

+	(HtmlFormatter::html_source_quote): Link to field ID if possible.

+	(HtmlFormatter::print_html_field_list): Emit `id' attribute.

+2014-11-29  Werner Lemberg  <[email protected]>

+	[docmaker] Allow empty lines in `<Order>' blocks.

+	Before this patch, the suggested order of entries stopped at the

+	first empty line.

+	Obviously, nobody noticed that this problem caused a much reduced

+	set of links in the `Synopsis' sections; in particular, the

+	`<Order>' blocks contain a lot of entries that wouldn't be listed

+	otherwise...

+	* src/tools/docmaker/content.py (DocBlock::get_markup_words_all):

+	New function to iterate over all items.

+	(DocSection::process): Use it.

+2014-11-29  Werner Lemberg  <[email protected]>

+	* src/tools/docmaker/sources.py (column) [Format 2]: Fix regexp.

+	After the single asterisk there must be no other immediately following

+	asterisk.

+2014-11-29  Werner Lemberg  <[email protected]>

+2014-11-29  Werner Lemberg  <[email protected]>

+	[docmaker] Provide higher-level markup and simplify HTML.

+	* src/tools/docmaker/tohtml.py: Instead of using extraneous `<div>'

+	elements, use CSS descendants (of class `section') to format the

+	data.

+	Also remove reduntant <p> and <br> elements, replacing them with

+	proper CSS.

+	Globally reduce page width to 75%.

+	(block_header): Rename <div> class to `section'.

+2014-11-29  Werner Lemberg  <[email protected]>

+	[docmaker] Add `top' links after blocks.

+	* src/tools/docmaker/tohtml.py (block_footer_middle): Implement it.

+2014-11-29  Werner Lemberg  <[email protected]>

+	* src/tools/docmaker/tohtml.py: Improve CSS for fields.

+	Make fields align horizontally relative to full line width.

+2014-11-29  Werner Lemberg  <[email protected]>

+	* src/tools/docmaker/tohtml.py: Fix index and TOC templates.

+	This thinko was introduced 2014-11-27.

+2014-11-28  Werner Lemberg  <[email protected]>

+	[docmaker] Format field lists with CSS.

+	This also simplifies the inserted HTML code.

+	* src/tools/docmaker/tohtml.py

+	(HtmlFormatter::print_html_field_list): Do it.

+2014-11-28  suzuki toshiya  <[email protected]>

+	Fix compiler warning to the comparison between signed and

+	unsigned variable.

+	* src/pfr/pfrsbit.c (pfr_slot_load_bitmap): Fix the comparison

+2014-11-28  Werner Lemberg  <[email protected]>

+	[docmaker] Replace empty `<td>' with CSS.

+	* src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Do

+	it.

+2014-11-28  Werner Lemberg  <[email protected]>

+	[docmaker] Replace some `<table>' tags with `<h4>' and `<div>'.

+	* src/tools/docmaker/tohtml.py (marker_*): Use `<h4>'.

+	(source_*): Use `<div>'.

+	(HtmlFormatter::block_enter): s/<h4>/<h3>/.

+2014-11-28  suzuki toshiya  <[email protected]>

+	Fix compiler warning to conversion specifiers in debug messages.

+	* src/autofit/afhints.c (af_glyph_hints_dump_points): Add length

+	modifier to dump long integers.

+	(af_glyph_hints_dump_segments, af_glyph_hints_dump_edges): Ditto.

+2014-11-27  Werner Lemberg  <[email protected]>

+	* src/tools/docmaker/tohtml.py: Use more CSS for index.

+2014-11-27  Werner Lemberg  <[email protected]>

+	[docmaker] Replace `name' attribute of `<a>' with `id'.

+	* src/tools/docmaker/tohtml.py (HtmlFormatter::block_enter): Do it.

+2014-11-27  Werner Lemberg  <[email protected]>

+	* src/tools/docmaker/tohtml.py: Remove remaining `width' attributes.

+	For `Index' and `TOC' links, we now simply use the `text-align' CSS

+	property of `<td>' to enforce flush-left and flush-right,

+	eliminating the hack with an empty, full-width `<td>' element

+	inbetween.

+	The change also enforces the same (smaller) size for all index and

+	TOC links.

+2014-11-27  suzuki toshiya  <[email protected]>

+	* src/cff/cf2font.c: Include `ftcalc.h' to use FT_MSB(),

+	unrequired negative value check for `width' and `height'.

+2014-11-27  Werner Lemberg  <[email protected]>

+	* src/tools/docmaker/tohtml.py: More HTML table refactoring.

+	Replace some `<table>' tags with `<div>' to simplify structure.

+	Move `bgcolor' attribute to CSS.

+	Replace most `width' attributes with CSS.  The remaining instances

+	(providing a similar effect as LaTeX's `\hfill' command) are removed

+	in a later patch.

+2014-11-27  Werner Lemberg  <[email protected]>

+	* src/tools/docmaker/tohtml.py: Replace <font> with CSS.

+2014-11-27  Werner Lemberg  <[email protected]>

+	This starts a series of commits into the direction of generating

+	valid HTML 5 code, especially using much more CSS.

+2014-11-27  suzuki toshiya  <[email protected]>

+	Prevent too negative values (< FT_INT_MIN) in bitmap metrics,

+	Don't cast cmap init function pointers to an incompatible type.

+	Without this patch, the number of parameters between declaration and

+	undefined behavior.

+	  ISO/IEC 9899:TC3 (Committee Draft September 7, 2007)

+	    6.5.2.2 Function calls

+	      9 If the function is defined with a type that is not

+	        compatible with the type (of the expression) pointed to by

+	        the expression that denotes the called function, the

+	        behavior is undefined.

+	On certain platforms (c -> js with emscripten) this causes

+	termination of execution or invalid calls because in the emscripten

+	implementation, function pointers of different types are stored in

+	different pointer arrays.  Incorrect pointer type here results in

+	indexing of an incorrect array.

+	[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

+	[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.

+2014-04-05  Werner Lemberg  <[email protected]>

+	[autofit] Improve scoring algorithm for identifying stems.

+	Problem reported by Karsten Lücke <[email protected]>.

+	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.

+2014-04-03  Werner Lemberg  <[email protected]>

+	Don't require `gzip' module for `sfnt'.

+2014-03-27  Werner Lemberg  <[email protected]>

+	Fix Savannah bug #38235.

+	Work around a bug in pkg-config version 0.28 and earlier: If a

+	for the `prefix' variable), the prefix override mechanism fails.

+	* builds/unix/freetype2.in: Don't use doublequotes.

+	* builds/unix/unix-def.in (freetype.pc): Escape spaces in directory

+2014-03-04  Werner Lemberg  <[email protected]>

+	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  <[email protected]>

+2014-03-03  Werner Lemberg  <[email protected]>

+	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'

+	Problem reported by Hin-Tak Leung <[email protected]>.

+	* builds/unix/configure.raw: Don't use gcc's `-pedantic' flag for

+2014-02-28  Dave Arnold  <[email protected]>

+	[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  <[email protected]>

+	[cff] Fix Savannah bug #41697, part 1.

+	* src/cff/cf2hints.c (cf2_hintmap_build): Return when `hintMask' is

+	`hStemHintArray'; the exception has already been recorded in

+	`hintMask'.

+2014-02-26  Werner Lemberg  <[email protected]>

+2014-02-26  Werner Lemberg  <[email protected]>

+	[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.

+2014-02-08  Dave Arnold  <[email protected]>

+	[cff] Fix minor performance bug.

+	* src/cff/cf2font.c (cf2_font_setup): Darkening amount and blue zone

+	[autofit] Don't combine multiple features into one set.

+	Combining them, as originally envisioned, would lead to much more

+	[ftrfork] Fix the face order difference between POSIX and Carbon.

+	The fragmented resources in Suitcase and .dfont should be reordered

+	HarfBuzz gets split into two libraries to avoid mutual dependencies

+	between FreeType and HarfBuzz.

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

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

+	incorrect amount of darkening.

+2013-10-02  Dave Arnold  <[email protected]>

+	* 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  <[email protected]>

+	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.

+2013-07-16  David Turner  <[email protected]>

+	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:
