 2013-05-04  Werner Lemberg  <wl@gnu.org>

 	[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'.

 	* src/cff/cf2ft.c (cf2_getBlueValues, cf2_getOtherBlues,

 	cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Updated.

 	* src/cff/cf2blues.c (cf2_blues_init): Updated.

 	More fixes for clang's `sanitize' feature.

 	* src/base/ftcalc.c (FT_DivFix): Use unsigned values for

 	computations which use the left shift operator and convert to signed

 	as the last step.

 	* src/base/fttrigon.c (ft_trig_prenorm, FT_Vector_Rotate,

 	FT_Vector_Length, FT_Vector_Polarize): Ditto.

 	* src/cff/cffgload.c (cff_decoder_parse_charstrings): Simplify.

 	* src/cff/cffload.c (cff_subfont_load): Fix constant.

 	* src/cff/cffparse.c (cff_parse_integer, cff_parse_real, do_fixed,

 2013-05-04  Werner Lemberg  <wl@gnu.org>

 	Fix errors reported by clang's `sanitize' feature.

 	* include/freetype/internal/ftstream.h: Simplify and fix integer

 	extraction macros.

 	(FT_INT8_, FT_BYTE_I16, FT_BYTE_I32, FT_INT8_I16, FT_INT8_I32,

 	FT_INT8_I32, FT_INT8_U32): Removed.

 	(FT_PEEK_SHORT, FT_PEEK_LONG, FT_PEEK_OFF3, FT_PEEK_SHORT_LE,

 	FT_PEEK_LONG_LE, FT_PEEK_OFF3_LE): Use unsigned values for

 	computations and convert to signed as the last step.

 	* src/cff/cf2fixed.h (cf2_intToFixed, cf2_fixedToInt,

 	cf2_fracToFixed): Avoid shifts of negative values.

 	(cf2_intToFrac, cf2_fixedToFrac, cf2_fixedTo26Dot6): Removed,

 	unused.

 	* src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdEXTENDEDNMBR,

 	default>: Use unsigned values for computations and convert to signed

 	as the last step.

 	Use proper types in tracing messages.

 	* src/cff/cffgload.c (cff_decoder_parse_charstrings): Use unsigned

 	values for computation of operands and convert to signed as the last

 	step.

 	Use proper type in tracing message.

 	* docs/CHANGES: Updated.

 	* README: Improved.

 2013-04-13  Werner Lemberg  <wl@gnu.org>

 	[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.

 	For convenience, (most of) the new files are committed separately.

 	* include/freetype/config/ftheader.h (FT_CFF_DRIVER_H): New macro.

 	* include/freetype/ftcffdrv.h: New file to access CFF driver

 	properties.

 	* include/freetype/fterrdef.h (FT_Err_Glyph_Too_Big): New error

 	code.

 	* include/freetype/internal/fttrace.h: Add `cf2blues', `cf2hints',

 	and `cf2interp'.

 	* src/cff/cffgload.h (CFF_SubFont): New member `current_subfont'.

 	* src/cff/cffobjs.h (CFF_DriverRec): New members `hinting_engine'

 	and `no_stem_darkening'.

 	* src/cff/cfftypes.h (CFF_FontRec): New member `cf2_instance'.

 	* src/cff/cff.c: Include new files.

 	* src/cff/cffdrivr.c (cff_property_set, cff_property_get): Handle

 	`hinting-engine' and `no-stem-darkening' properties (only the Adobe

 	engine listens to them).

 	* src/cff/cffgload.c: Include `cf2ft.h'.

 	(cff_decoder_prepare): Initialize `current_subfont'.

 	(cff_build_add_point): Handle Adobe engine which uses 16.16

 	coordinates.

 	(cff_slot_load): Handle FT_LOAD_NO_SCALE and FT_LOAD_NO_HINTING

 	separately.

 	Choose rendering engine based on `hinting_engine' property.

 	* src/cff/cffload.c (cff_font_done): Call finalizer of the Adobe

 	engine.

 	* src/cff/cffobjs.c: Include FT_CFF_DRIVER_H.

 	(cff_driver_init): Set default property values.

 	* src/cff/rules.mk (CFF_DRV_SRC, CFF_DRV_H): Add new files.

 	* src/cff/cf2*.*: New files, containing the Adobe engine.

 2013-04-12  Werner Lemberg  <wl@gnu.org>

 	[cff] Minor code administration issues.

 	* src/cff/cffgload.c (check_points): Rename to...

 	(cff_check_points): ...this and make it FT_LOCAL.

 	(cff_builder_add_point, cff_builder_add_point1,

 	cff_builder_start_point, cff_builder_close_contour,

 	cff_lookup_glyph_by_stdcharcode, cff_get_glyph_data,

 	cff_free_glyph_data): Make them FT_LOCAL.

 	* src/cff/cffgload.h: Updated.

 2013-04-12  Werner Lemberg  <wl@gnu.org>

 	Add output bitmap checksums.

 	Use `FT2_DEBUG=bitmap:3' for tracing.

 	* src/base/md5.c, src/base/md5.h: New files, taken from

 	  http://openwall.info/wiki/people/solar/software/public-domain-source-code/md5

 	* include/freetype/internal/fttrace.h: Add `bitmap'.

 	* src/base/ftobjs.c [FT_DEBUG_LEVEL_TRACE]: Include `md5.c'

 	(FT_Render_Glyph_Internal) [FT_DEBUG_LEVEL_TRACE]: For tracing,

 	convert resulting bitmap to a uniform format and compute a checksum.

 	Use `bitmap' category for the tracing message.

 	* src/base/rules.mk (BASE_H): Updated.

 	* docs/LICENSE.TXT: Updated.

 2013-04-12  Werner Lemberg  <wl@gnu.org>

 	[cff] Add framework for CFF properties.

 	* include/freetype/internal/ftserv.h (FT_DEFINE_SERVICEDESCREC7):

 	New macro.

 	* src/cff/cffdrivr.c: Include FT_SERVICE_PROPERTIES_H.

 	(cff_property_set, cff_property_get): New functions, still empty.

 	Define `cff_service_properties' service.

 	* src/cff/cffpic.h: Include FT_SERVICE_PROPERTIES_H.

 	(CFF_SERVICE_PROPERTIES_GET): New macro.

 	(CffModulePIC): Add `cff_service_properties'.

 2013-04-03  Werner Lemberg  <wl@gnu.org>

 	[bdf] Fix Savannah bug #38589.

 	* src/bdf/bdflib.c (_bdf_readstream): Thinko.

 2013-03-31  Werner Lemberg  <wl@gnu.org>

 	* configure: Use egrep, not grep.

 	Problem reported Mojca Miklavec <mojca.miklavec.lists@gmail.com>.

 2013-03-29  Werner Lemberg  <wl@gnu.org>

 	* include/freetype/ftlcdfil.h: Add description of color filtering.

 	Based on a contribution from Antti S. Lankila <alankila@bel.fi>

 	(Savannah bug #38607).

 2013-03-23  Werner Lemberg  <wl@gnu.org>

 	[autofit] Minor.

 	* src/autofit/afmodule.c (af_property_set): Typo.

 	(af_autofitter_init, af_autofitter_done): Use cast.

 2013-03-21  Werner Lemberg  <wl@gnu.org>

 	* configure: Automatically test for `gmake' also.

 	Suggested by Mojca Miklavec <mojca.miklavec.lists@gmail.com>.

 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>

 	Fix Savannah patch #7971.

 	* configure: Handle MAKE environment variable also.

 2013-03-17  Werner Lemberg  <wl@gnu.org>

 	Fix Savannah bug #38538.

 	* builds/amiga/src/base/ftdebug.c, builds/win32/ftdebug.c,

 	builds/wince/ftdebug.c (FT_Throw): Add function.

 2013-03-17  Werner Lemberg  <wl@gnu.org>

 	[raster] Remove dead code.

 	* src/raster/rastpic.c (ft_raster1_renderer_class_pic_init)

 	src/smooth/ftspic.c (ft_smooth_renderer_class_pic_init): Do it.

 2013-03-17  Werner Lemberg  <wl@gnu.org>

 	* src/pshinter/pshpic.h (GET_PIC): Use correct container.

 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>

 	[gxvalid] Fix module error.

 	* src/gxvalid/gxverror.h (FT_ERR_BASE): Define as

 	FT_Mod_Err_GXvalid.

 	* include/freetype/ftmoderr.h: Add module error for `GXvalid'.

 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

 	`FT_ERROR_BASE'.

 	* src/type1/t1load.c (parse_encoding): Use

 	T1_Err_Unknown_File_Format.

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

 	[cff] Set `linear{Hori,Vert}Advance' for embedded bitmaps also.

 	Problem reported by Khaled Hosny <khaledhosny@eglug.org>.

 	* src/cff/cffgload.c (cff_slot_load): Implement it.

 2013-02-23  Alexei Podtelezhnikov  <apodtele@gmail.com>

 	[base] Fix commit ab02d9e8.

 	* src/base/ftbbox.c (BBox_Cubic_Check): Change scaling to msb of 22.

 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

 	for extremum search built around simple condition that defines

 	which half contains the extremum.

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

 	[tools] Update BBox testing tool.

 	* src/tools/test_bbox.c: Add another cubic outline with exact BBox.

 	(REPEAT): Increase the number of benchmarking cycles.

 	(profile_outline): Tweak output formatting.

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

 	Fix Savannah bug #38235.

 	* builds/unix/configure.raw: Don't generate `freetype-config' and

 	`freetype.pc'.

 	* builds/unix/unix-def.in (FT2_EXTRA_LIBS, LIBBZ2, LIBZ,

 	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

 	substitution marker.

 	Use quotes.

 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.

 	* src/truetype/ttinterp.c (Ins_IP): Implement identical behaviour to

 	MS rasterizer if rp1 == rp2 (confirmed by Greg Hitchcock).

 2013-02-01  Alexei Podtelezhnikov  <apodtele@gmail.com>

 	[pcf] Streamline parsing of PCF encoding table.

 	* src/pcf/pcfread.c (pcf_get_encodings): Use simpler double for-loop.

 	Reallocate array instead of using temporary storage.

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

 	Fix Savannah bug #38227.

 	* builds/unix/freetype-config.in: Set LC_ALL.

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

 	Fix Savannah bug #38221.

 	This complements commit 83c0ebab.

 	* src/base/ftcalc.c (FT_MulDiv_No_Round): Don't enclose with

 	`TT_USE_BYTECODE_INTERPRETER'.

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

 	[truetype] Fix Savannah bug #38211.

 	* src/truetype/ttinterp.c (Ins_IP): Make FreeType behave identical

 	to other interpreters if rp1 == rp2 (which is invalid).

 2013-01-28  Alexei Podtelezhnikov  <apodtele@gmail.com>

 	[base] Small optimization of BBox calculation.

 	* src/base/ftbbox.c (BBox_Cubic_Check): Use FT_MSB function in

 	scaling algorithm.

 2013-01-26  Infinality  <infinality@infinality.net>

 	[truetype] Minor formatting fix.

 	* src/truetype/ttinterp.c: Updated.

 	[sfnt] Fix broken pointer overflow checks.

 	Many compilers such as gcc and clang optimize away pointer overflow

 	checks `p + n < p', because pointer overflow is undefined behavior.

 	Use a safe form `n > p_limit - p' instead.

 	Also avoid possible integer overflow issues, for example, using

 	`num_glyphs > ( p_limit - p ) / 2' rather than `num_glyphs * 2'

 	given a large `num_glyphs'.

 2013-01-16  David 'Digit' Turner  <digit@google.com>

 	[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...

 	Update all users.

 2013-01-12  Alexei Podtelezhnikov  <apodtele@gmail.com>

 	[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.

 	* src/truetype/ttinterp.c (Normalize): Scale short vectors by 0x4000.

 2013-01-12  Alexei Podtelezhnikov  <apodtele@gmail.com>

 	[truetype] Kill very old vector normalization hacks.

 	Back in the days, vector length calculations were not very accurate

 	and the vector normalization function, Normalize, had to meticulously

 	correct the errors for long vectors [commit b7ef2b096867]. It was no

 	longer necessary after accurate CORDIC algorithms were adopted, but

 	the code remained. It is time to kill it.

 	* src/truetype/ttinterp.c (Normalize): Remove error compensation.

 	(TT_VecLen): Remove any mention of old less accurate implementation.

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

 	[base] Reduce trigonometric algorithms.

 	After we get within 45 degrees by means of true 90-degree rotations,

 	we can remove initial 45-degree CORDIC iteration and start from

 2012-12-20  Alexei Podtelezhnikov  <apodtele@gmail.com>

 	[base] Improve trigonometric core.

 	FreeType used to rely on a 24-step iteration CORDIC algorithm to

 	calculate trigonometric functions and rotate vectors. It turns out

 	that once the vector is in the right half-plane, the initial rotation

 	by 63 degrees is not necessary. The algorithm is perfectly capable

 	to converge to any angle starting from the second 45 degree rotation.

 	This patch removes the first rotation and makes it a 23-step CORDIC

 	algorithm.

 	* src/base/fttrigon.c (FT_TRIG_SCALE, FT_TRIG_COSCALE): Update macro

 	values.

 	(ft_trig_pseudo_rotate, ft_trig_pseudo_polarize): Remove initial

 	rotation.

 	Various compiler warning fixes.

 	* include/freetype/internal/ftserv.h (FT_SERVICE_UNAVAILABLE): Use

 	`logical not' operator instead of negation.  The idea is that `~'

 	this flexibility.

 	* src/cache/ftccmap.c (FTC_CMAP_UNKNOWN): Ditto.

 	Since the initial commit (ebe85f59) the value of FT_TRIG_SCALE has

 	always been slightly less than the correct value, which has been

 	given in the comment as a hexadecimal. As a result, vector lengths

 	were underestimated and rotated vectors were shortened.

 	* src/base/fttrigon.c (FT_TRIG_SCALE): Fix macro value.

 2012-12-10  Alexei Podtelezhnikov  <apodtele@gmail.com>

 	[truetype] Scale F_dot_P down.

 	The dot product between freeVector and projVector or cosine of

 	the angle between these FT_F2Dot14 unit vectors used to be scaled up

 	by 4 and routinely occupied 32 bits in an FT_Long field F_dot_P.

 	This patch scales the value down by 2^14 instead, which simplifies

 	its use throughout the bytecode interpreter.

 	This does not lead to the loss of precision because the lower bits

 	are unreliable anyway. Consider two unit vectors (1,0) and (.6,.8)

 	for which the true value of F_dot_P is .6 * 0x40000000 = 0x26666666.

 	These vectors are stored as (0x4000,0) and (0x2666,0x3333) after

 	rounding and F_dot_P is assigned 0x26660000. The lower bits were

 	already lost while rounding the unit vector components.

 	Besides code simplification, this change can lead to better

 	performance when FT_MulDiv with the scaled-down F_dot_P is less

 	likely to use the costly 64-bit path. We are not changing the type

 	of F_dot_P to FT_F2Dot14 at this point.

 	* src/truetype/ttinterp.c (Compute_Funcs): Scale F_dot_P down by 14

 	bits and modify its use accordingly.

 	(Direct_Move, Direct_Move_Orig, Compute_Point_Displacement): Modify

 	the use of F_dot_P field.

 	* src/truetype/ttobjs.c (tt_size_run_fpgm): Change arbitrary

 	assignment of F_dot_P to its theoretical maximum in case we decide

 	to scale back its type later.

 2012-06-30  Gilles Espinasse  <g.esp@free.fr>

 	Fix `checking if gcc static flag -static works' test.

 	On my linux build tree, I receive yes answer in in every package I

 	build except freetype for this test checking if gcc static flag

 	`-static' works

 	On freetype, no is received, unless bzip2 and zlib are disabled using

 	  ./configure --without-bzip2 --without-zlib

 	The reason is that bzip2 and zlib tests add `-lz' and `-lbz2' to

 	LDFLAGS and this broke static flag test.

 	* builds/unix/configure.raw: Update CFLAGS and LDFLAGS only after

 	LT_INIT has run.

 2012-06-28  Infinality  <infinality@infinality.net>

 	[truetype] Fix various artifacts.

 	Verdana was broken in the original Infinality commit.  Also

 	includes other minor fixes.

 	* src/truetype/ttsubpix.h: Updated.  Removed unused macros.

 	(RASTERIZER_35_Rules): Add Verdana.

 	(SKIP_NONPIXEL_Y_MOVES_Rules): Add Tahoma `s'.

 	(MIRP_CVT_ZERO_Rules): Remove Verdana.

 	(ALWAYS_SKIP_DELTAP_Rules): Add Russian char 0x438.

 	(COMPATIBLE_WIDTHS_Rules): Rearrange some rules.

 2012-06-26  Infinality  <infinality@infinality.net>

 	[truetype] Remove unused rounding functionality.

 	The subpixel hinting patch contained the concept of an adjustable

 	number of gridlines per pixel.  This is no longer used due to x

 	being completely ignored instead.  This will return some of the

 	code to its existing state prior to the original Infinality

 	commit.

 	* include/freetype/internal/ftobjs.h (FT_PIX_FLOOR_GRID,

 	FT_PIX_ROUND_GRID, FT_PIX_CEIL_GRID): Removed.

 	(Move_Zp2_Point, Ins_SHPIX, Ins_MSIRP, Ins_MDAP, Ins_MIAP,

 	Ins_MDRP, Ins_MIRP): Perform Round_None instead of calling a modified

 	rounding function.  Remove gridlines_per_pixel.  Create a local

 	variable to store control value cutin. Simplify the conditional for

 	ignore_x_mode.  Adjust rounding calls to pass only two values.

 2012-06-18  Infinality  <infinality@infinality.net>

 	[truetype] Support subpixel hinting.

 	This is the large, famous `Infinality' patch to support ClearType

 	bytecode which has been available from

 	http://www.infinality.net/blog/ for some time, and which has been

 	refined over the last years.  While still experimental, it is now

 	mature enough to be included directly into FreeType.

 	Most of the code is based on the ClearType whitepaper written by

 	Greg Hitchcock

 	  http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx

 	which gives a detailed overview of the necessary changes to the

 	Microsoft rasterizer so that older fonts are supported.  However, a

 	lot of details are still missing, and this patches provides a

 	framework to easily handle rendering issues down to the glyph level

 	of certain fonts.

 	Note that ClearType support is not completely implemented!  In

 	particular, full support for the options `compatible_widths',

 	`symmetrical_smoothing, and `bgr' (via the GETINFO bytecode

 	instruction) is missing.

 	* src/truetype/ttsubpix.c: New file, providing code to handle

 	`tweaks', this is, rules for certain glyphs in certain fonts

 	(including wildcards) which need a special treatment.

 	* src/truetype/ttsubpix.h: New file, holding the tweaking rules.

 	* include/freetype/config/ftoption.h, src/devel/ftoption.h

 	(TT_CONFIG_OPTION_SUBPIXEL_HINTING): New macro.

 	* include/freetype/internal/ftobjs.h (FT_PIX_FLOOR_GRID,

 	FT_PIX_ROUND_GRID, FT_PIX_CEIL_GRID): New macros.

 	* src/truetype/truetype.c [TT_USE_BYTECODE_INTERPRETER]: Include

 	`ttsubpix.c'.

 	* src/truetype/ttgload.c: Include `ttsubpix.h'.

 	[All changes below are guarded by TT_CONFIG_OPTION_SUBPIXEL_HINTING.]

 	(tt_get_metrics): Set tweak flags.

 	(TT_Hint_Glyph): Call `FT_Outline_EmboldenXY' if necessary.

 	(TT_Process_Simple_Glyph): Compensate emboldening if necessary.

 	(compute_glyph_metrics): Handle `compatible widths' option.

 	(tt_loader_init): Handle ClearType GETINFO information bits.

 	* src/truetype/rules.mk (TT_DRC_SRC): Updated.

 	* src/truetype/ttinterp.c: Include `ttsubpix.h'.

 	[Where necessary, changes below are guarded by

 	TT_CONFIG_OPTION_SUBPIXEL_HINTING.]

 	(Direct_Move, Direct_Move_X): Extended.

 	(Round_None, Round_To_Grid, Round_To_Half_Grid, Round_Down_To_Grid,

 2012-03-11  Werner Lemberg  <wl@gnu.org>

 	[autofit] Return correct linear advance width values.

 	This was quite a subtle bug which accidentally showed up with glyph

 	`afii10023' of arial.ttf (version 2.76).  This glyph is a composite;

 	the first component, `E', has an advance width of 1366 font units,

 	while the advance width of the composite itself (which looks like

 	uppercase `E' with dieresis) is 1367 font units.  I think this is

 	actually a bug in the font itself, because there is no reason that

 	this glyph has not the same width as uppercase `E' without the

 	dieresis.  Anyway, it helped identify this problem.

 	Using the TrueType hinter, the correct value (1367) of `afii10023'

 	was returned, but the autohinter mysteriously returned 1366.

 	Digging in the code showed that the autohinter recursively calls

 	FT_Load_Glyph to load the glyph, adding the FT_LOAD_NO_SCALE load

 	flag.  However, the `linearHoriAdvance' field is still returned as a

 	scaled value.  To avoid scaling twice, the old code in autofit reset

 	`linearHoriAdvance', using the `horiAdvance' field.  This seemed to

 	work since FT_LOAD_NO_SCALE was in use, but it failed actually,

 	because `horiAdvance' is defined as the distance of the first

 	subglyph's phantom points, which in turn are initialized using the

 	advance width of the first subglyph.  And as the given example

 	shows, these widths can differ.

 	* src/autofit/afloader.c (af_loader_load_g): Temporarily set

 	FT_LOAD_LINEAR_DESIGN while calling FT_Load_Glyph to get unscaled

 	values for the linear advance widths.

 2012-03-10  Werner Lemberg  <wl@gnu.org>

 	[truetype] Fix SSW instruction.

 	* src/truetype/ttinterp.c (DO_SSW): SSW *does* use font units.  For
