  120 	[mac] Fix ftexport.sym target in Jamfile.
  121 
  122 	* Jamfile: Update the directories of the header files scanned for
  123 	ftexport.sym.  They were incorrect since the migration of the
  124 	header files, on 2015-06-22.  Either inexisting include/cache
  125 	(removed on 2006-03-20) is not needed to be listed explicitly.
  126 	Now ftmac.h is scanned only in the case of Mac OS & Mac OS X.

  130 	[smooth] Sub-banding protocol revision.
  131 
  132 	Rasterization sub-banding is utilized at large sizes while using a
  133 	rather small fixed memory pool.  Indeed it is possible to make an
  134 	educated guess how much memory is necessary at a given size for a
  135 	given glyph.  It turns out that, for a large majority of European
  136 	glyphs, you should store about 8 times more boundary pixels than
  137 	their height.  Or, vice versa, if your memory pool can hold 800
  138 	pixels the band height should be 100 and you should sub-band
  139 	anything larger than that.  Should you still run out of memory,
  140 	FreeType bisects the band but you have wasted some time.  This is
  141 	what has been implemented in FreeType since the beginning.
  142 
  143 	It was overlooked, however, that the top band could grow to twice
  144 	the default band size leading to unnecessary memory overflows there.
  145 	This commit fixes that.  Now the bands are distributed more evenly
  146 	and cannot exceed the default size.
  147 
  148 	Now the magic number 8 is really suitable for rather simple European
  149 	scripts.  For complex Chinese logograms the magic number should be
  150 	13 but that is subject for another day.
  151 
  152 	* src/smooth/ftgrays.c (gray_convert_glyph): Revise sub-banding
  153 	protocol.

  156 
  157 	[mac] Fix Savannah bug #48417.
  158 
  159 	Mac OS X linker throws errors when `-exported_symbol_list' input
  160 	file includes non-existing symbols.  Reported by Ryan Schmidt.
  161 
  162 	* builds/exports.mk: Exclude ftmac.h from the headers for apinames
  163 	by default.  Include it when ftmac.c would be compiled.

  220

  224 
  225 	* src/autofit/aflatin.c (af_latin_hints_compute_segments): Don't

  450 
  451 	* src/autofit/afranges.c: Remove `UL' postfix from hex numbers.
  452 
  453 	Suggested by Alexei.  `UL' is only needed for 16bit compilers, but
  454 	it seems noone is using this anymore (and we no longer test whether
  455 	FreeType compiles in such an environment).  Otherwise, it is easy to

  460 	[smooth] Shrink bisection stack.
  461 
  462 	The convergence of Bézier flatteners is fast with the deviation

  498 	* builds/unix/unix-cc.in (LINK_LIBRARY): Use `-export-symbols'.
  499 
  500 	This was commented about 10 years ago – I think the reason then to
  501 	disable libtool's `-export-symbols' option was to give some badly
  502 	programmed applications access to internal FreeType functions.
  503

  783 
  784 	[autofit] Add support for Georgian scripts.
  785 
  786 	Georgian is problematic, since `uppercase' forms of Mkhedruli
  787 	(called Mtavruli) are not yet defined in Unicode, which means that
  788 	proper blue zones can't be defined.  However, there is already a
  789 	proposal submitted to Unicode; see
  790 
  791 	  https://www.unicode.org/L2/L2016/16034-n4707-georgian.pdf
  792 
  793 	Additionally, due to historical reasons, Unicode treats Khutsuri as
  794 	the same script as Mkhedruli, and so does OpenType.  However, since
  795 	the two scripts have completely different shapes it can happen that
  796 	blue zones differ considerably.  The tag `geok' used here (derived
  797 	from ISO 15924) to differentiate the two scripts is not an OpenType
  798 	tag in use.  If we now have a font that contains both glyphs for
  799 	Mkhedruli and Khutsuri, and it uses OpenType features for both also,
  800 	HarfBuzz unavoidably treats all glyphs as `geor'.  As a consequence,
  801 	blue zones for `geok' are not used for glyphs involved in the
  802 	OpenType features.
  803 
  804 	An issue not yet resolved is which OpenType feature should be used
  805 	to access Mtavruli glyph shapes; right now, FreeType doesn't set up
  806 	support for them, but it is easy to add them later on as soon as
  807 	more information is available.

  874 
  875 	We did a binary search for a charcode without ensuring that the
  876 	searched data is ordered.  Validating the order is now done lazily,
  877 	this is, the first access to a bitmap glyph triggers the order check
  878 	in the corresponding bitmap strike.
  879 
  880 	* src/pfr/pfrtypes.h (PFR_BitmapFlags): New values

  896 
  897 	* src/pfr/pfrgload.c (pfr_glyph_load_simple,
  898 	pfr_glyph_load_compound): Use them.
  899

 1019 
 1020 	[truetype] Fix handling of non-intermediate GX tuples.
 1021 
 1022 	We probably did not notice this as all fonts we tested had only

 1024 
 1025 	* src/truetype/ttgxvar.c (ft_var_apply_tuple): Implement it.

 1027 2016-03-06  Alexei Podtelezhnikov  <apodtele@gmail.com>

 1029 	[base] Refuse to render enormous outlines (#47114).
 1030 
 1031 	The goal is to avoid integer overflows in the rendering algorithms.
 1032 	The limit is chosen arbitrarily at some 2^18 pixels, which should be
 1033 	enough for modern devices including printers.
 1034 
 1035 	* src/base/ftoutln.c (FT_Outline_Render): Check CBox and reject
 1036 	enormous outlines.

 1121 	* src/autofit/aflatin.c (af_latin_hints_compute_segments): Properly
 1122 	handle segments where the last point of the first segment is
 1123 	identical to the first point in the second one.  This can happen for
 1124 	malformed fonts or spikes.  We either merge the new segment with the
 1125 	previous one (both segments point into the same direction), or we

 1138 	[autofit] Improve BOUND action.
 1139 
 1140 	In complex glyph shapes, the original logic was too simple to cater
 1141 	for situations that would actually need something similar to PS Hint
 1142 	masks.  This fix should alleviate the worst cases.
 1143 
 1144 	* src/autofit/aflatin.c (af_latin_hint_edges): Don't allow

 1494 
 1495 	[autofit] Fix handling of default script.
 1496 
 1497 	Patch taken from ttfautohint, commit
 1498 	071ae2c00e0d67f9d19418f4fade1c23d27dc185.
 1499 
 1500 	There were two bugs.
 1501 
 1502 	  - We now use non-standard script tags like `khms' for special
 1503 	    purposes.  However, HarfBuzz maps such tags to `DFLT', and
 1504 	    without this commit the associated lookups were incorrectly
 1505 	    assigned to the non-standard tags.
 1506 
 1507 	  - Let's assume we have a Bengali font, and the font's `DFLT'
 1508 	    script tag handles the necessary lookups for Bengali, too.
 1509 	    Without this commit, the `DFLT' lookups were assigned to
 1510 	    ttfautohint's default script (usually `latn') before the
 1511 	    standard lookups for Bengali were handled.
 1512 
 1513 	    We now have the following order while searching for covered
 1514 	    glyph indices.
 1515 
 1516 	      special features of scripts (e.g. `sups' for Cyrillic)
 1517 	      Unicode mappings of scripts
 1518 	      remaining features of scripts (especially important for Indic
 1519 	        scripts)
 1520 	      default features of default script
 1521 
 1522 	* src/autofit/afshaper.c, src/autofit/afshaper.h
 1523 	(af_shaper_get_coverage): Add boolean parameter to indicate default
 1524 	script.
 1525 	Update all callers.
 1526 
 1527 	* src/autofit/afglobal.c (af_face_globals_compute_style_coverage):
 1528 	Fix search order for coverages.
 1529 
 1530 2016-01-19  Werner Lemberg  <wl@gnu.org>
 1531

 1931 
 1932 	[autofit] Introduce subscript top blue zones.
 1933 
 1934 	This feature is mainly for Khmer: The idea is to avoid a clash
 1935 	between the top of subscript glyphs and the bottom of normal
 1936 	baseline glyphs.
 1937 
 1938 	This only works for character clusters mapped to multiple glyphs.
 1939 
 1940 	* src/autofit/afblue.dat: Add subscript top blue zone for Khmer.

 1979 2015-12-06  Werner Lemberg  <wl@gnu.org>
 1980 
 1981 	[autofit] Add support for Khmer script.
 1982 
 1983 	We split Khmer into two auto-hinter scripts: `Khmer' (`khmr') and

 1985 
 1986 	* src/autofit/afblue.dat: Add blue zone data for Khmer.

 1997 
 1998 	[autofit] Rewrite HarfBuzz interface to support character clusters.
 1999 
 2000 	Scripts like Khmer have blue zones that can't be directly
 2001 	represented by Unicode characters.  Instead, it is necessary to let
 2002 	HarfBuzz convert character clusters into proper glyph representation
 2003 	forms, then deriving the blue zone information from the resulting
 2004 	glyphs.
 2005 
 2006 	* src/autofit/hbshim.c, src/autofit/hbshim.h: Replaced by...
 2007 	* src/autofit/afshaper.c, src/autofit/afshaper.h: ... these two new
 2008 	files, providing a new API to access HarfBuzz.
 2009 
 2010 	The new API manages a HarfBuzz buffer with `af_shaper_buf_create'
 2011 	and `af_shaper_buf_destroy'.  The buffer receives a UTF8 encoded
 2012 	string with function `af_shaper_get_cluster', and the resulting
 2013 	glyph data (indices, advance widths, vertical offsets) can be
 2014 	iteratively accessed with function `af_shaper_get_elem'.
 2015 
 2016 	* src/autofit/afcjk.c (af_cjk_metrics_init_widths,
 2017 	af_cjk_metrics_init_blues, af_cjk_metrics_check_digits): Updated.

 2041 	* src/autofit/aflatin.c (af_latin_metrics_init_blues): Add dummy
 2042 	loop.  No functional change.
 2043 
 2044 2015-12-06  Werner Lemberg  <wl@gnu.org>
 2045 
 2046 	[autofit] Use string of standard characters.
 2047 
 2048 	This is more flexible; additionally, it would allow character
 2049 	clusters.
 2050 
 2051 	* src/autofit/aftypes.h (SCRIPT, AF_DEFINE_SCRIPT_CLASS): Updated.
 2052 	(AF_ScriptClassRec): Replace `standard_char[123]' with

 2075 
 2076 	* src/tools/afblue.pl (convert_ascii_chars): Don't ignore spaces.
 2077 
 2078 	Instead, reduce multiple spaces to a single one.  We need this later
 2079 	for supporting character clusters in `afblue.dat'.
 2080 
 2081 2015-12-05  Werner Lemberg  <wl@gnu.org>
 2082

 2434 	Currently, libFuzzer only supports mutation of a single file.  We

 2931 	[smooth] Faster alternative line renderer.
 2932 
 2933 	This implementation renders the entire line segment at once without
 2934 	subdividing it into scanlines.  The main speed improvement comes from
 2935 	reducing the number of divisions to just two per line segment, which
 2936 	is a bare minimum to calculate cell coverage in a smooth rasterizer.
 2937 	Notably, the progression from cell to cell does not itself require any
 2938 	divisions at all.  The speed improvement is more noticeable at larger

 3209 
 3210 	This patch fixes weaknesses in function `tt_face_load_font_dir'.
 3211 
 3212 	- It incorrectly assumed that valid tables are always at the

 3450 	[autofit] Redesign code ranges (1/2).
 3451 
 3452 	This patch introduces auxiliary code ranges that identify no-base
 3453 	characters; they refer to glyphs of a script that should be hinted
 3454 	without alignments to blue zones (mostly diacritics).
 3455 
 3456 	It also splits off ranges for fallback scripts that handle subscript
 3457 	and superscript characters not covered by OpenType features.  For
 3458 	example, this greatly helps improve the hinting of various phonetic
 3459 	alphabets, which contain a large amount characters that look like
 3460 	superscript glyphs.
 3461 
 3462 	Finally, code ranges are updated to Unicode 8.0, and enclosed
 3463 	characters are removed in general since they normally look better if

 3638 
 3639 	[type42] Fix glyph access.
 3640 
 3641 	This is a severe bug: We've missed one level of indirection, as
 3642 	described in the Type 42 specification.  As a result, ftview
 3643 	sometimes showed incorrect glyphs for given glyph names, and even
 3644 	displayed `error 0x0006' (invalid argument!) in case the number of
 3645 	glyph indices differed between the Type 42 font and the embedded
 3646 	TTF.
 3647 
 3648 	Apparently, noone ever noticed it; this shows how much Type 42 fonts
 3649 	are in use...
 3650

 3720 
 3721 	* src/base/ftcalc.c (ft_corner_orientation): On 32-bit systems, stay

 3920 2015-06-25  Werner Lemberg  <wl@gnu.org>
 3921 
 3922 	* CMakeLists.txt: Use cmake functions for generating `ftconfig.h'.
 3923 	Additionally, do this for UNIX only.

 3925 2015-06-25  Werner Lemberg  <wl@gnu.org>
 3926 
 3927 	* CMakeLists.txt (BASE_SRCS): Use `ftbase.c' and `psnames.c'.
 3928 
 3929 2015-06-25  Werner Lemberg  <wl@gnu.org>
 3930 
 3931 	Another adjustment to header locations.
 3932 
 3933 	This change is a result of a discussion thread on freetype-devel

 3941 	* include/freetype2: Renamed to...
 3942 	* include/freetype: This.
 3943 
 3944 	* CMakeLists.txt (PUBLIC_HEADERS, PUBLIC_CONFIG_HEADERS,

 3991 2015-06-22  Werner Lemberg  <wl@gnu.org>
 3992 
 3993 	Fix Savannah bug #45097.
 3994 
 3995 	We no longer `pollute' the namespace of possible header file names;
 3996 	instead we move `ft2build.h' up by one level so that it gets
 3997 	installed in the default include directory (e.g.,
 3998 	/usr/local/include).  After this commit, only `ft2build.h' stays in
 3999 	the compiler's include path.
 4000 
 4001 	No visible changes for the user who follows the standard FreeType
 4002 	header inclusion rules.
 4003 
 4004 	* include/*: Move to ...

 4028 
 4029 2015-06-21  Werner Lemberg  <wl@gnu.org>
 4030 
 4031 	Make Jam support work again.
 4032 
 4033 	This is just very basic stuff and just a little bit tested on
 4034 	GNU/Linux only.  I won't delve into this since I'm not a Jam user.
 4035 
 4036 	* Jamfile: Call `HDRMACRO' for `ftserv.h' also.
 4037 	(DEFINES): Replace with...
 4038 	(CCFLAGS): ... this.
 4039 
 4040 	* src/Jamfile: Don't call `HDRMACRO' for `internal.h'; this is
 4041 	already handled in the top-level Jamfile.
 4042 
 4043 	* src/autofit/Jamfile (DEFINES): Replace with...
 4044 	(CCFLAGS): ... this.
 4045 	(_sources): Add missing files.
 4046 
 4047 	* src/cache/Jamfile: Don't call `HDRMACRO' for `ftcache.h'; it no
 4048 	longer contains macro header definitions.
 4049 
 4050 	* src/base/Jamfile, src/cff/Jamfile, src/sfnt/Jamfile,
 4051 	src/truetype/Jamfile (_sources): Add missing files.

 4112 
 4113 	[truetype] Fix memory leak.
 4114 
 4115 	Problem reported by Grissiom <chaos.proton@gmail.com>; in
 4116 
 4117 	  https://lists.nongnu.org/archive/html/freetype/2015-05/msg00013.html
 4118 
 4119 	there is an example code to trigger the bug.
 4120 
 4121 	* src/truetype/ttobjs.c (tt_size_init_bytecode): Free old `size'
 4122 	data before allocating again.  Bug most probably introduced four
 4123 	years ago in version 2.4.3.
 4124 
 4125 2015-06-02  Werner Lemberg  <wl@gnu.org>
 4126 
 4127 	[raster] Add more tracing.
 4128 
 4129 	* src/raster/ftraster.c (FT_TRACE7) [_STANDALONE_]: Define.
 4130 	(Vertical_Sweep_Span, Vertical_Sweep_Drop, Horizontal_Sweep_Span,
 4131 	Horizontal_Sweep_Drop, Render_Glyph): Add tracing calls.
 4132 
 4133 2015-06-01  Werner Lemberg  <wl@gnu.org>
 4134 
 4135 	[truetype] While tracing opcodes, show code position and stack.
 4136 
 4137 	* src/truetype/ttinterp.c: Change all existing TRACE7 calls to
 4138 	TRACE6.
 4139 	(opcode_name): Add string lengths.
 4140 	(TT_RunIns): Implement display of code position and stack.
 4141 
 4142 2015-05-31  Werner Lemberg  <wl@gnu.org>
 4143 
 4144 	[truetype] In GX, make private point numbers work correctly.
 4145 
 4146 	This is completely missing in Apple's documentation: If a `gvar'
 4147 	tuple uses private point numbers (this is, deltas are specified for
 4148 	some points only), the uncovered points must be interpolated for
 4149 	this tuple similar to the IUP bytecode instruction.  Examples that
 4150 	need this functionality are glyphs `Oslash' and `Q' in Skia.ttf.
 4151 
 4152 	* src/truetype/ttgxvar.c (tt_delta_shift, tt_delta_interpolate,
 4153 	tt_handle_deltas): New functions.
 4154 	(TT_Vary_Get_Glyph_Deltas): Renamed to...
 4155 	(TT_Vary_Apply_Glyph_Deltas): ... this; it directly processes the
 4156 	points and does no longer return an array of deltas.
 4157 	Add tracing information.
 4158 	Call `tt_handle_deltas' to interpolate missing deltas.
 4159 	Also fix a minor memory leak in case of error.
 4160 
 4161 	* src/truetype/ttgxvar.h: Updated.
 4162 
 4163 	* src/truetype/ttgload.c (TT_Process_Simple_Glyph,
 4164 	load_truetype_glyph): Updated.
 4165 
 4166 2015-05-31  Werner Lemberg  <wl@gnu.org>
 4167 
 4168 	[truetype] In GX, make intermediate tuplets work at extrema.
 4169 
 4170 	* src/truetype/ttgxvar.c (ft_var_apply_tuple): Fix range condition.
 4171 
 4172 2015-05-31  Werner Lemberg  <wl@gnu.org>
 4173 
 4174 	[truetype] Add tracing information to GX code.
 4175 
 4176 	* src/truetype/ttgxvar.c (ft_var_load_avar, ft_var_load_gvar,
 4177 	ft_var_apply_tuple, TT_Get_MM_Var, TT_Set_MM_Blend,
 4178 	TT_Set_Var_Design, tt_face_vary_cvt): Do it.
 4179 
 4180 2015-05-28  Werner Lemberg  <wl@gnu.org>
 4181

 4188 
 4189 	[truetype] Fix commit from 2015-05-22.
 4190 
 4191 	* src/truetype/ttgload.c, src/truetype/ttinterp.c: Guard new code
 4192 	with `TT_CONFIG_OPTION_SUBPIXEL_HINTING'.
 4193 
 4194 	Problem reported by Nikolaus Waxweiler <madigens@gmail.com>.
 4195 
 4196 2015-05-23  Werner Lemberg  <wl@gnu.org>
 4197 
 4198 	[truetype] Fix return values of GETINFO bytecode instruction.
 4199 
 4200 	* src/truetype/ttinterp.h (TT_ExecContextRec): New fields
 4201 	`vertical_lcd' and `gray_cleartype'.
 4202 
 4203 	* src/truetype/ttgload.c (tt_loader_init): Initialize new fields.
 4204 	Change `symmetrical smoothing' to TRUE, since FreeType produces
 4205 	exactly this.
 4206 
 4207 	* src/truetype/ttinterp.c (Ins_GETINFO): Fix selector/return bit
 4208 	values for symmetrical smoothing, namely 11/18.
 4209 	Handle bits for vertical LCD subpixels (8/15) and Gray ClearType
 4210 	(12/19).
 4211 
 4212 2015-05-23  Werner Lemberg  <wl@gnu.org>
 4213

 4217 	 s/subpixel/subpixel_hinting.
 4218 
 4219 	* src/truetype/ttgload.c, src/truetype/ttgload.h: Updated.
 4220 
 4221 2015-05-22  Werner Lemberg  <wl@gnu.org>
 4222 
 4223 	[truetype] Support selector index 3 of the INSTCTRL instruction.
 4224 
 4225 	This flag activates `native ClearType hinting', disabling backward
 4226 	compatibility mode as described in Greg Hitchcocks whitepaper.  In
 4227 	other words, it enables unrestricted functionality of all TrueType
 4228 	instructions in ClearType.
 4229 
 4230 	* src/truetype/ttgload.c (tt_get_metrics): Call `sph_set_tweaks'
 4231 	unconditionally.
 4232 	(tt_loader_init): Unset `ignore_x_mode' flag if bit 2 of
 4233 	`GS.instruct_control' is active.
 4234 
 4235 	* src/truetype/ttinterp.c (Ins_INSTCTRL): Handle selector index 3.
 4236 	(Ins_GETINFO): Updated.
 4237 
 4238 	* docs/CHANGES: Document it.
 4239 
 4240 2015-05-20  Werner Lemberg  <wl@gnu.org>
 4241 
 4242 	[truetype] Minor.
 4243

 4245 	argument.
 4246 
 4247 2015-05-17  Werner Lemberg  <wl@gnu.org>
 4248 
 4249 	[truetype] Fix loading of composite glyphs.
 4250 
 4251 	* src/truetype/ttgload.c (TT_Load_Composite_Glyph): If the
 4252 	ARGS_ARE_XY_VALUES flag is not set, handle argument values as
 4253 	unsigned.  I trust `ttx' (which has exactly such code) that it does
 4254 	the right thing here...
 4255 
 4256 	The reason that noone has ever noticed this bug is probably the fact
 4257 	that point-aligned subglyphs are rare, as are subglyphs with a
 4258 	number of points in the range [128;255], which is quite large (or
 4259 	even in the range [32768;65535], which is extremely unlikely).
 4260 
 4261 2015-05-12  Chris Liddell  <chris.liddell@artifex.com>
 4262 
 4263 	[cff] Make the `*curveto' operators more tolerant.
 4264 
 4265 	* src/cff/cf2intrp.c (cf2_interpT2CharString): The opcodes
 4266 	`vvcurveto', `hhcurveto', `vhcurveto', and `hvcurveto' all iterate,
 4267 	pulling values off the stack until the stack is exhausted.
 4268 	Implicitly the stack must be a multiple (or for subtly different
 4269 	behaviour) a multiple plus a specific number of extra values deep.
 4270 	If that's not the case, enforce it (as the old code did).
 4271 
 4272 2015-05-12  Chris Liddell  <chris.liddell@artifex.com>
 4273 
 4274 	[cff] fix incremental interface with new cff code.
 4275 
 4276 	* src/cff/cf2ft.c (cf2_getSeacComponent): When using the incremental
 4277 	interface to retrieve glyph data for a SEAC, it be left to the
 4278 	incremental interface callback to apply the encoding to raw
 4279 	character index (as it was in the previous code).
 4280 
 4281 2015-04-29  Alexei Podtelezhnikov  <apodtele@gmail.com>
 4282 
 4283 	[autofit] Speed up IUP.
 4284 
 4285 	* src/autofit/afhints.c (af_iup_interp): Separate trivial snapping to
 4286 	the same position from true interpolation, use `scale' to reduce
 4287 	divisions.
 4288 
 4289 2015-04-28  Werner Lemberg  <wl@gnu.org>
 4290 
 4291 	[cff] Use `name' table for PS name if we have a SFNT-CFF.
 4292 
 4293 	This follows the OpenType 1.7 specification.  See

 4295 	  https://tug.org/pipermail/tex-live/2015-April/036634.html
 4296 
 4297 	for a discussion.

 4744 
 4745 	* src/cache/ftccache.h (FTC_NodeRec): `FT_Offset' (a.k.a. `size_t')
 4746 	is a better choice for `hash' to hold a pointer than `FT_PtrDist'
 4747 	(a.k.a. `ptrdiff_t'), especially since the latter is signed,
 4748 	causing zillions of signedness warnings.  [Note that `hash' was of

 5160 	It certainly doesn't harm since it is similar to already existing

 5204 	[raster] Fix Savannah bug #44022.
 5205 
 5206 	Add fallback for glyphs with degenerate bounding boxes.
 5207 
 5208 	If a glyph has only one very narrow feature, the bbox can end up
 5209 	with either the width or height of the bbox being 0, in which case
 5210 	no raster memory is allocated and no attempt is made to render the
 5211 	glyph.  This is less than ideal when the drop-out compensation in
 5212 	the rendering code would actually result in the glyph being
 5213 	rendered.
 5214 
 5215 	This problem can be observed with the `I' glyph (gid 47) in the
 5216 	Autodesk RomanS TrueType font.
 5217 
 5218 	* src/raster/ftrend1.c (ft_raster1_render): Add a fallback if either
 5219 	dimension is zero to explicitly round up/down (instead of simply
 5220 	round).

 5228 	is no longer used to track years of modification changes.
 5229 
 5230 	* src/tools/update-copyright-year: New Perl script.

 5246 	[autofit] Add embedded array of segments and edges.
 5247 
 5248 	Avoids multiple mallocs per typical glyphs.
 5249 
 5250 	With this and recent changes to avoid mallocs, the thread-safe
 5251 	stack-based loader is now as fast as the previous model that had one
 5252 	cached singleton.
 5253

 5281 	[autofit] Allocate hints object on the stack.
 5282 
 5283 	This avoids one malloc per load.
 5284 
 5285 	* src/autofit/afloader.h (AF_LoaderRec): Change type of `hints' to

 5292 	(af_loader_load_g): Updated.

 5298 
 5299 	[autofit] Reuse slot glyph loader.
 5300 
 5301 	No need to create a new glyph loader; we can reuse the one from
 5302 	`slot->internal->loader'.  It's hard to tell why it was written that
 5303 	way originally, but new code looks sound and correct to me, and
 5304 	avoids lots of allocations.
 5305 
 5306 	* src/autofit/afloader.c (af_loader_init): Change return type to
 5307 	`void'.
 5308 	Don't call `FT_GlyphLoader_New'.
 5309 	(af_loader_reset): Don't call `FT_GlyphLoader_Rewind'.
 5310 	(af_loader_load_g): Update code to use `internal->loader', which
 5311 	doesn't need copying of data.
 5312 
 5313 	* src/autofit/afloader.h (AF_LoaderRec): Remove `gloader' member.

 5318 2015-01-14  Behdad Esfahbod  <behdad@behdad.org>
 5319 
 5320 	[autofit] Remove (unused) support for composite glyphs.
 5321 
 5322 	We never have to deal with composite glyphs in the autohinter, as
 5323 	those will be loaded into FORMAT_OUTLINE by the recursed
 5324 	`FT_Load_Glyph' function.
 5325 
 5326 	In the rare cases that FT_LOAD_NO_RECURSE is set, it will imply
 5327 	FT_LOAD_NO_SCALE as per `FT_Load_Glyph', which then implies
 5328 	FT_LOAD_NO_HINTING:
 5329 
 5330 	  /* resolve load flags dependencies */
 5331 
 5332 	  if ( load_flags & FT_LOAD_NO_RECURSE )
 5333 	    load_flags |= FT_LOAD_NO_SCALE         |
 5334 	                  FT_LOAD_IGNORE_TRANSFORM;
 5335 
 5336 	  if ( load_flags & FT_LOAD_NO_SCALE )
 5337 	  {
 5338 	    load_flags |= FT_LOAD_NO_HINTING |
 5339 	                  FT_LOAD_NO_BITMAP;
 5340 
 5341 	    load_flags &= ~FT_LOAD_RENDER;
 5342 	  }
 5343 
 5344 	and as such the auto-hinter is never called.  Thus, the recursion in
 5345 	`af_loader_load_g' never actually happens.  So remove the depth
 5346 	counter as well.
 5347 
 5348 	* src/autofit/afloader.c (af_loader_load_g): Remove `depth'
 5349 	parameter.
 5350 	<FT_GLYPH_FORMAT_COMPOSITE>: Remove associated code.
 5351 	(af_loader_load_glyph): Updated.

 5353 2015-01-14  Behdad Esfahbod  <behdad@behdad.org>
 5354 
 5355 	[raster] Fix uninitialized memory access.
 5356 
 5357 	Apparently `ras.cProfile' might be uninitialized.  This will be the
 5358 	case if `ras.top == ras.cProfile->offset', as can be seen in
 5359 	`End_Profile'.  The overshoot code introduced in a change `Fix B/W
 5360 	rasterization of subglyphs with different drop-out modes.' (from
 5361 	2009-06-18) violated this, accessing `ras.cProfile->flags'
 5362 	unconditionally just before calling `End_Profile' (which then
 5363 	detected that `cProfile' is uninitialized and didn't touch it).
 5364 
 5365 	This was harmless, and was not detected by valgrind before because
 5366 	the objects were allocated on the `raster_pool', which was always
 5367 	initialized.  With recent change to allocate raster buffers on the
 5368 	stack, valgrind now reported this invalid access.
 5369 
 5370 	* src/raster/ftraster.c (Convert_Glyph): Don't access an
 5371 	uninitialized `cProfile'.
 5372 
 5373 2015-01-14  Behdad Esfahbod  <behdad@behdad.org>
 5374 
 5375 	[smooth] Fix uninitialized memory access.
 5376 
 5377 	Looks like `ras.span_y' could always be used without initialization.
 5378 	This was never detected by valgrind before because the library-wide
 5379 	`raster_pool' was used for the worker object and `raster_pool' was
 5380 	originally zero'ed.  But subsequent reuses of it were using `span_y'
 5381 	uninitialized.  With the recent change to not use `render_pool' and
 5382 	allocate worker and buffer on the stack, valgrind now detects this
 5383 	uninitialized access.
 5384 
 5385 	* src/smooth/ftgrays.c (gray_raster_render): Initialize
 5386 	`ras.span_y'.

 5388 2015-01-14  Behdad Esfahbod  <behdad@behdad.org>

 5397 
 5398 	[base] Don't allocate `library->raster_pool' anymore.

 5402 	  [raster] Allocate render pool for mono rasterizer on the stack.
 5403 	  [raster] Remove 5-level gray AA mode from monochrome rasterizer.
 5404 
 5405 	The value of FT_RENDER_POOL_SIZE still serves the purpose it used to
 5406 	serve, which is, to adjust the pool size.  But the pool is now
 5407 	allocated on the stack on demand.
 5408 
 5409 	* src/base/ftobjs.c (FT_New_Library, FT_Done_Library): Implement.
 5410 
 5411 2015-01-14  Behdad Esfahbod  <behdad@behdad.org>

 5414 
 5415 	Instead of keeping `library->renderers' in a MRU order, just leave
 5416 	it as-is.  The MRU machinery wasn't thread-safe.
 5417 
 5418 	With this patch, rasterizing glyphs from different faces from
 5419 	different threads doesn't fail choosing rasterizer
 5420 	(FT_Err_Cannot_Render_Glyph).
 5421 
 5422 	Easiest to see that crash was to add a `printf' (or otherwise let

 5495 	[truetype] Allocate TT_ExecContext in TT_Size instead of TT_Driver.
 5496 
 5497 	Previously the code had stipulation for using a per-TT_Size exec
 5498 	context if `size->debug' was true.  But there was no way that
 5499 	`size->debug' could *ever* be true.  As such, the code was always
 5500 	using the singleton `TT_ExecContext' that was stored in `TT_Driver'.
