+	CFF_CONFIG_OPTION_OLD_ENGINE.
+	* devel/ftoption.h: Define CFF_CONFIG_OPTION_OLD_ENGINE.
+
+2013-06-19  Werner Lemberg  <wl@gnu.org>
+
+	* builds/unix/install.mk (install): Don't create `cache' directory.
+
+	Found by Peter Breitenlohner <peb@mppmu.mpg.de>.

+
+	Tag sources with `VER-2-5-0'.
+
+	* docs/VERSION.DLL: Update documentation and bump version number to
+	2.5.0.

+
+	* include/freetype/freetype.h (FREETYPE_MINOR): Set to 5.
+	(FREETYPE_PATCH): Set to 0.
+
+	* builds/unix/configure.raw (version_info): Set to 16:2:10.
+
+	* src/base/ftobjs.c (FT_Open_Face): Pacify compiler.
+	* src/truetype/ttinterp.c (Ins_MSIRP, Ins_MIRP): Ditto.
+
+2013-06-18  Werner Lemberg  <wl@gnu.org>
+
+	Fix Savannah bug #39269.
+
+	* src/base/ftgloadr.c (FT_GlyphLoader_CheckPoints): Free memory in
+	case of reacollocation failures.
+
+2013-06-18  Andrew Church  <achurch+savannah@achurch.org>
+
+	Fix Savannah bug #39266.
+
+	If memory allocations fail at certain points while opening a font,
+	FreeType can either crash due to a NULL dereference or leak memory.
+
+	* include/freetype/internal/ftobjs.c (FT_Face_InternalRec,
+	FT_LibraryRec): Make `refcount' a signed integer.  If, for example,
+	FT_Open_Face() fails in a memory allocation before the face's
+	reference count is set to 1, a subsequent `FT_Done_Library' call
+	would otherwise loop over `FT_Done_Face' 2^32 times before freeing
+	the face.
+
+	* src/base/ftobjs.c (open_face): Initialize `stream' and friends
+	earlier.
+	(FT_Open_Face) <Fail>: Behave correctly if `node' is NULL.
+	(FT_Destroy_Module) <Fail>: Check that `renderer_clazz' is valid.
+
+2013-06-14  Werner Lemberg  <wl@gnu.org>
+
+	* src/smooth/ftgrays.c One final pragma to silence 64-bit MSVC.
+
+2013-06-06  Dave Arnold  <darnold@adobe.com>
+	    Werner Lemberg  <wl@gnu.org>
+
+	[cff] Add code to Adobe's engine to handle ppem > 2000.
+
+	* src/cff/cffgload.c (cff_slot_load): If we get
+	FT_Err_Glyph_Too_Big, retry unhinted and scale up later on.
+
+2013-06-12  Werner Lemberg  <wl@gnu.org>
+
+	Another try on pragmas.
+
+	* include/freetype/internal/ftdebug.h: Move pragmas to...
+	* include/freetype/internal/internal.h: ... this file since it gets
+	included by all source files.
+	* include/freetype/internal/ftserv.h: Remove pragma which has no
+	effect.
+
+2013-06-12  Werner Lemberg  <wl@gnu.org>
+
+	* include/freetype/internal/ftdebug.h: Disable MSVC warning C4127.
+
+	This partially undoes commit 3f6e0e0c.
+
+2013-06-12  Werner Lemberg  <wl@gnu.org>
+
+	More compiler warning fixes.
+
+	*/*: Use cast to `FT_Bool' (or `Bool') where appropriate.
+
+2013-06-10  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Improve handling of broken sbit advance widths.
+
+	* src/truetype/ttgload.c (TT_Load_Glyph): Use the glyph's (scaled)
+	`linearHoriAdvance' if the sbit's `horiAdvance' value is zero.
+
+	Cf. font `Fixedsys Excelsior' v3.01 (FSEX300.ttf), glyph A, 16ppem.
+
+2013-06-10  Werner Lemberg  <wl@gnu.org>
+
+	[sfnt] Improve embedded bitmap tracing.
+
+	* src/base/ftobjs.c (FT_Request_Size): Move trace message regarding
+	bitmap strike match to...
+	(FT_Match_Size): This function.
+
+	* src/sfnt/ttsbit.c (tt_sbit_decoder_load_metrics,
+	tt_sbit_decoder_load_byte_aligned, tt_sbit_decoder_load_bit_aligned,
+	tt_sbit_decoder_load_compound, tt_sbit_decoder_load_png,
+	tt_sbit_decoder_load_image): Decorate with tracing messages.
+
+2013-06-10  Werner Lemberg  <wl@gnu.org>

+	* src/truetype/ttinterp.c (Ins_SDPVTL): Set projection vector too
+	for the degenerate case.
+
+2013-06-09  David Turner  <digit@google.com>
+
+	* src/cache/ftcmanag.c (FTC_Manager_Reset): Add missing cache flush.
+
+	This code, present since eight(!) years in the unused `CACHE'
+	branch, has been forgotten to apply to the master branch.  It's
+	really amazing that noone has ever complained since
+	`FTC_Manager_Reset' is pretty useless without flushing the cache.
+
+2013-06-07  Werner Lemberg  <wl@gnu.org>
+

+
+2013-06-06  Dave Arnold  <darnold@adobe.com>
+
+	[cff] Add early exit feature for width-only calls.
+
+	This is for `FT_Get_Advance'.
+
+	There are 7 places where the spec says the width can be defined:
+
+	  hstem/hstemhm
+	  vstem/vstemhm
+	  cntrmask/hintmask
+	  hmoveto
+	  vmoveto
+	  rmoveto
+	  endchar
+
+	* src/cff/cf2intrp.c (cf2_doStems): Exit early for width-only calls,
+	if possible.
+
+	(cf2_interpT2CharString) <cf2_cmdHSTEM>, <cf2_cmdVSTEM>,
+	<cf2_cmdVMOVETO>, <cf2_cmdENDCHAR>, <cf2_cmdHINTMASK>,

+
+	Problem reported by Ingmar Sittl <ingmar.sittl@elektrobit.com>.
+
+2013-06-04  Werner Lemberg  <wl@gnu.org>
+
+	Apply fixes for cppcheck nitpicks.
+
+	  http://cppcheck.sourceforge.net/
+
+	The call was (from the top-level of the FreeType tree):
+
+	  cppcheck --force \
+	           --enable=all \
+	           -I include \
+	           -I include/freetype/ \
+	           -I include/freetype/config/ \
+	           -I include/freetype/internal/ \
+	           . &> cppcheck.log
+
+	Note that the current version heavily chokes on FreeType, delivering
+	many wrong results.  I will report those issues to the cppcheck team
+	so that a newer version gives improved results hopefully.
+
+	*/* Improve variable scopes.
+	*/* Remove redundant initializations which get overwritten.
+
+	* src/base/ftmac.c ,builds/mac/ftmac.c (count_faces_scalable):
+	Remove unused variable.
+
+	* src/base/ftdbgmem.c (ft_mem_table_destroy): `table' can't be zero.

+
+2013-06-03  Werner Lemberg  <wl@gnu.org>
+
+	Add CFF_CONFIG_OPTION_OLD_ENGINE configuration option.
+
+	This controls whether the old FreeType CFF engine gets compiled into
+	FreeType.  It is now disabled by default.
+
+	* devel/ftoption.h, include/freetype/config/ftoption.h
+	(CFF_CONFIG_OPTION_OLD_ENGINE): New macro.
+
+	* src/cff/cffdrivr.c (cff_property_set), src/cff/cffgload.c
+	(CFF_Operator, cff_argument_counts, cff_builder_add_point,
+	cff_operator_seac, cff_decoder_parse_charstrings, cff_slot_load),

+	LIBPNG_LDFLAGS.
+
+2013-05-23  Behdad Esfahbod  <behdad@google.com>
+
+	Add support for color embedded bitmaps (eg. color emoji).
+
+	A new load flag, FT_LOAD_COLOR, makes FreeType load color
+	embedded-bitmaps, following this draft specification
+
+	  https://color-emoji.googlecode.com/git/specification/v1.html
+
+	which defines two new SFNT tables, `CBDT' and `CBLC' (named and
+	modeled after `EBDT' and `EBLC', respectively).  The color bitmaps
+	are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA
+	pre-multiplied sRGB images.  If PNG support is available, PNG color
+	images as defined in the same proposed specification are supported
+	also.
+
+	Note that color bitmaps are converted to grayscale if client didn't
+	ask for color.
+
+	* builds/unix/configure.raw: Search for libpng.

+	(OutputFormat): Add `OUTPUT_NETWARE_IMP'.
+	(names_dump): Handle it.
+	(usage): Updated.
+	(main): Handle new command line flag `-wN'.

+	[cff] Make Adobe CFF engine work correctly on 64bit hosts.
+
+	Reported by numerous people on the `freetype-devel' list.  Without
+	this fix, glyphs aren't properly aligned on a common baseline.
+
+	On 64bit systems, `FT_Pos' expands to `long int', having a width of
+	64bit.  `CF2_Fixed' expands to `int' which is normally 32bit wide on
+	64bit hosts also.  Wrong casts filled up the blues arrays with
+	incorrect values.  Note that all blues values are accessed with the
+	`cf2_blueToFixed' macro which handles the 64bit to 32bit conversion.
+
+	* src/cff/cf2ft.h (cf2_getBlueValues, cf2_getOtherBlues,
+	cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Use `FT_Pos' for
+	`data', not `CF2_Fixed'.

+
+	[cff] Add a new Type 2 interpreter and hinter.
+
+	This work, written by Dave Arnold <darnold@adobe.com> and fully
+	integrated into FreeType by me, is a donation by Adobe in
+	collaboration with Google.  It is vastly superior to the old CFF
+	engine, and it will replace it soon.  Right now, it is still off by
+	default, and you have to explicitly select it using the new
+	`hinting-engine' property of the cff driver.

+
+2013-03-21  Peter Breitenlohner  <peb@mppmu.mpg.de>
+
+	Respect CONFIG_SHELL from the environment.
+
+	Some large packages using FreeType have to use a broken (deficient)
+	/bin/sh.  The configure scripts (as generated by Autoconf) are
+	clever enough to find a better shell and put that one into the
+	environment variable CONFIG_SHELL.  If that environment variable is
+	already set the script skips the test and assumes to be already
+	running under a good shell.
+
+	* builds/unix/detect.mk: Honour CONFIG_SHELL.
+	* builds/unix/unix-def.in (SHELL): Define.
+
+2013-03-21  Werner Lemberg  <wl@gnu.org>
+

+
+2013-03-15  Werner Lemberg  <wl@gnu.org>
+
+	* include/freetype/ftmoderr.h: Fix commit from 2013-03-11.
+
+	The previous version was not backwards compatible.  Reported by
+	Behdad.
+
+2013-03-14  Werner Lemberg  <wl@gnu.org>
+
+	*/*: Use FT_ERR_EQ, FT_ERR_NEQ, and FT_ERR where appropriate.
+
+	FT_Err_XXX and friends are no longer directly used in the source
+	code.
+
+2013-03-14  Werner Lemberg  <wl@gnu.org>
+
+	New error management macros.
+
+	* include/freetype/fterrors.h (FT_ERR_XCAT, FT_ERR_CAT): Move to...
+	* include/freetype/fttypes.h: ... this file.
+	(FT_ERR, FT_ERR_EQ, FT_ERR_NEQ, FT_MODERR_EQ, FT_MODERR_NEQ): New
+	macros.
+
+	* include/freetype/freetype.h: Updated.
+
+2013-03-14  Werner Lemberg  <wl@gnu.org>
+
+	*/*: Use FT_Err_Ok only.
+
+	This is a purely mechanical conversion.
+
+2013-03-14  Werner Lemberg  <wl@gnu.org>
+
+	*/*: Use `FT_THROW'.
+
+	This is essentially a mechanical conversion, adding inclusion of
+	`FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for
+	stand-alone compiling modes of the rasterizer modules.
+
+	To convert the remaining occurrences of FT_Err_XXX and friends it is
+	necessary to rewrite the code.  Note, however, that it doesn't harm
+	if some cases are not handled since FT_THROW is a no-op.
+
+2013-03-13  Werner Lemberg  <wl@gnu.org>
+
+	Introduce `FT_THROW' macro.
+
+	The idea is to replace code like
+
+	  return FT_Err_Foo_Bar;
+
+	or
+
+	  return CFF_Err_Foo_Bar;
+
+	with
+
+	  return FT_THROW( Foo_Bar );
+
+	The FT_THROW macro has two functions:
+
+	  . It hides the module specific prefix.
+
+	  . In debug mode, it calls the empty function `FT_Throw' which can
+	    be thus used to set a breakpoint.
+
+	* include/freetype/internal/ftdebug.h (FT_THROW): New macro.
+	(FT_Throw): New prototype.
+	* src/base/ftdebug.c (FT_Throw): New function.
+
+2013-03-12  Werner Lemberg  <wl@gnu.org>
+
+	Remove `FT_KEEP_ERR_PREFIX'.
+
+	The idea is to always have FT_ERR_PREFIX available internally.
+
+	* include/freetype/fterrors.h: Use FT2_BUILD_LIBRARY to guard
+	undefinition of FT_ERR_PREFIX
+
+	* src/gxvalid/gxverror.h, src/otvalid/otverror.h,
+	src/sfnt/sferrors.h: Updated.
+
+2013-03-11  Werner Lemberg  <wl@gnu.org>

+
+2013-03-11  Werner Lemberg  <wl@gnu.org>
+
+	Always use module related error codes.
+
+	* src/cff/cffobjs.c (cff_face_init), src/type1/t1objs.c
+	(T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Use

+
+2013-03-08  Werner Lemberg  <wl@gnu.org>

+2013-02-19  Alexei Podtelezhnikov  <apodtele@gmail.com>
+
+	[base] New bisecting BBox_Cubic_Check (disabled).
+
+	* src/base/ftbbox.c (BBox_Cubic_Check): New bisecting algorithm

+
+2013-02-18  Alexei Podtelezhnikov  <apodtele@gmail.com>
+

+
+2013-02-02  Werner Lemberg  <wl@gnu.org>
+
+	Fix Savannah bug #38235.
+

+	build_libtool_libs, ft_version): New variables to be substituted.
+	(freetype-config, freetype.pc): New rules to generate those files.
+
+	* builds/unix/freetype-config.in: Remove code for handling `rpath'.
+	The use of $rpath has been accidentally removed in a patch from
+	2009-12-22, and apparently noone has missed it since.
+	Use `%' instead of `@' as a variable substitution marker.
+	Use quotes.
+
+	* builds/unix/freetype.in: Use `%' instead of `@' as a variable

+
+2013-02-07  Werner Lemberg  <wl@gnu.org>
+
+	* src/truetype/ttobjs.c (tt_size_run_prep): Reset more GS variables.
+
+	BTW, Greg agrees that the OpenType specification is missing the list
+	of GS variables which will always be reset to the default values
+	after the `prep' table has been executed.
+
+2013-02-06  Werner Lemberg  <wl@gnu.org>
+
+	* src/truetype/ttobjs.c (tt_size_run_prep): Reset reference points.
+
+	Up to now, we simply took a snapshot of the Graphics State after the
+	`prep' table has been executed, and right before a glyph's bytecode
+	was run it got reloaded.  However, as Greg Hitchcock has told us in
+	private communication, reference points get reset to zero in the MS
+	rasterizer and we follow in due course.  While reasonable, this is
+	undocumented behaviour.
+
+	Most notably, this fixes the rendering of Arial's `x' glyph in
+	subpixel hinting mode.

+2013-02-05  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] A better fix for Savannah bug #38211.

+
+	[pcf] Streamline parsing of PCF encoding table.

+
+2013-02-01  Werner Lemberg  <wl@gnu.org>

+
+	[truetype] Improve sub-pixel code.
+
+	This patches fixes many issues with the ttsubpix implementation.
+
+	1. Data tables are defined, instead of declared, in the header, and
+	   thus copied into each source file that includes it.
+
+	2. These tables were defined as global, mutable, visible variables,
+	   and thus costing private RAM to every process that loads the
+	   library (> 50 KB / process, this is huge!).
+
+	   Additionally, this also made the library export the symbols
+	   completely needlessly.
+
+	3. Missing `sph_' and `SPH_' prefixes to some of the definitions.
+
+	Note that this doesn't try to fix the incredibly inefficient storage
+	format for the data tables used by the code.  This one will require
+	another pass in the future.
+
+	* src/truetype/ttinterp.h (MAX_NAME_SIZE, MAX_CLASS_MEMBERS):
+	Renamed to...

+
+	[truetype] Improve accuracy of normalization of short vectors.
+
+	Unit vector components are stored as 2.14 fixed-point numbers. In
+	order to calculate all 14 bits accurately, a short vector to be
+	normalized has to be upscaled to at least 14 bits before its length
+	is calculated. This has been safe since accurate CORDIC algorithms
+	were adopted.

+
+	[truetype] Kill very old vector normalization hacks.
+
+	Back in the days, vector length calculations were not very accurate

+	longer necessary after accurate CORDIC algorithms were adopted, but
+	the code remained. It is time to kill it.
