2016-07-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[mac] Fix ftexport.sym target in Jamfile.
* Jamfile: Update the directories of the header files scanned for
ftexport.sym. They were incorrect since the migration of the
header files, on 2015-06-22. Either inexisting include/cache
(removed on 2006-03-20) is not needed to be listed explicitly.
Now ftmac.h is scanned only in the case of Mac OS & Mac OS X.

[smooth] Sub-banding protocol revision.
Rasterization sub-banding is utilized at large sizes while using a
rather small fixed memory pool. Indeed it is possible to make an
educated guess how much memory is necessary at a given size for a
given glyph. It turns out that, for a large majority of European
glyphs, you should store about 8 times more boundary pixels than
their height. Or, vice versa, if your memory pool can hold 800
pixels the band height should be 100 and you should sub-band
anything larger than that. Should you still run out of memory,
FreeType bisects the band but you have wasted some time. This is
what has been implemented in FreeType since the beginning.
It was overlooked, however, that the top band could grow to twice
the default band size leading to unnecessary memory overflows there.
This commit fixes that. Now the bands are distributed more evenly
and cannot exceed the default size.
Now the magic number 8 is really suitable for rather simple European
scripts. For complex Chinese logograms the magic number should be
13 but that is subject for another day.
* src/smooth/ftgrays.c (gray_convert_glyph): Revise sub-banding
protocol.
2016-07-07 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[mac] Fix Savannah bug #48417.
Mac OS X linker throws errors when `-exported_symbol_list' input
file includes non-existing symbols. Reported by Ryan Schmidt.

by default. Include it when ftmac.c would be compiled.
2016-07-06 Werner Lemberg <wl@gnu.org>

(gray_convert_glyph_inner): Trace successes and failures.
2016-07-04 Werner Lemberg <wl@gnu.org>
[autofit] Handle single-point contours as segments.
Doing so allows us to link them to edges – some fonts like
`NotoSansGurmukhi-Regular' have such isolated points sitting exactly
on other outlines.
* src/autofit/aflatin.c (af_latin_hints_compute_segments): Don't
ignore one-point contours but handle them specially as one-point
segments.
(af_latin_hints_compute_edges): Append one-point segments to edges
if possible.
2016-07-02 Werner Lemberg <wl@gnu.org>

This patch restores original `TCoord' definition as `int' so that the
rendering pool is used more efficiently on LP64 platforms (unix).
* src/smooth/ftgrays.c (gray_TWorker, TCell, gray_TBand): Switch some
fields to `TCoord'.
(gray_find_cell, gray_render_scanline, gray_render_line, gray_hline,
gray_sweep, gray_convert_glyph): Updated.
2016-06-28 Alexei Podtelezhnikov <apodtele@gmail.com>
[smooth] Minor clean-ups.
* src/smooth/ftgrays.c (gray_TWorker): Remove redundant `ycount'.
(gray_sweep, gray_convert_glyph, gray_dump_cells): Updated.
2016-06-27 Alexei Podtelezhnikov <apodtele@gmail.com>
[smooth] Minor clean-ups.
* src/smooth/ftgrays.c (gray_convert_glyph): Do not use volatile
qualifier.
(gray_raster_render): Move span initializations from here.
(gray_sweep): ... to here and remove unused `target' argument.
2016-06-26 Alexei Podtelezhnikov <apodtele@gmail.com>
[pcf] Fix handling of very large fonts (#47708).
* src/pcf/pcfread.c (pcf_get_encodings): Make `encodingOffset' an
unsigned short.
Only reject `0xFFFF' as an invalid encoding offset.
2016-06-25 Werner Lemberg <wl@gnu.org>

(gray_convert_glyph): ... to here and update accordingly.
2016-06-22 Alexei Podtelezhnikov <apodtele@gmail.com>
[smooth] Consolidate boundary checks.
Removing the checks from `gray_hline' shaves 1% off rendering speed.
* src/smooth/ftgrays.c [STANDALONE_]: Duplicate `FT_MIN' and `FT_MAX'.
(gray_TWorker): No need to store `clip_box'.
(gray_hline): Remove unnecessary boundary checks.
(gray_convert_glyph): Move boundary checks from here.
(gray_raster_render): ... to here and consolidate.
2016-06-21 Alexei Podtelezhnikov <apodtele@gmail.com>
[smooth] Use `FT_Outline_Get_CBox'.
* src/smooth/ftgrays.c [STANDALONE_]: Duplicate `FT_Outline_Get_CBox'.

2016-06-09 David Capello <davidcapello@gmail.com>
[cmake] Avoid modifying `ftconfig.h' and `ftoption.h' files.
* CMakeLists.txt: Each time cmake is run those files are
modified and the whole FreeType library is recompiled. With this
change we change the files only if there are real modifications, so
we can avoid recompilations.
2016-06-09 Werner Lemberg <wl@gnu.org>

2016-06-07 Werner Lemberg <wl@gnu.org>
[autofit] Fix compilation with VS2016 (#48126).
This compiler doesn't recognize the end-of-comment sequence `*/' if
it immediately follows non-ASCII characters.
* src/autofit/afscript.h: Ensure whitespace before `*/'.
2016-06-04 Werner Lemberg <wl@gnu.org>
Fix a test for named instances (#48122).
This was missed while giving negative face indices an extended
meaning.
* src/base/ftobjs.c (Mac_Read_sfnt_Resource): Implement.
2016-05-31 Nikolaus Waxweiler <madigens@gmail.com>
[truetype] Let SHPIX move points in the twilight zone in v40.
* src/truetype/ttinterp.c (Ins_SHPIX): Allow SHPIX to move points in
the twilight zone. Otherwise, treat SHPIX the same as DELTAP.
Unbreaks various fonts such as older versions of Rokkitt and DTL
Argo T Light that would glitch severely after calling ALIGNRP after a
blocked SHPIX.
2016-05-30 Werner Lemberg <wl@gnu.org>
[type42] Support `CharStrings' entry format as created by LilyPond.
* src/type42/t42parse.c (t42_parse_charstrings): Handle entries
having the format
(foo) cvn 12345 def
2016-05-28 Werner Lemberg <wl@gnu.org>
* src/autofit/afranges.c: Remove `UL' postfix from hex numbers.
Suggested by Alexei. `UL' is only needed for 16bit compilers, but
it seems noone is using this anymore (and we no longer test whether
FreeType compiles in such an environment). Otherwise, it is easy to
add the postfix to the `AF_UNICODE_RANGE' macro.
2016-05-26 Alexei Podtelezhnikov <apodtele@gmail.com>
[smooth] Shrink bisection stack.
The convergence of Bézier flatteners is fast with the deviation
from straight line being asymptotically cut 4-fold on each bisection.
This justifies smaller bisection stack size.
* src/smooth/ftgrays.c (gray_TWorker): Remove common `bez_stack'.
(gray_render_conic): Create and use conic `bez_stack'. Move back the
band analysis from...
(gray_conic_to): ... here.
(gray_render_cubic): Create and use cubic `bez_stack'. Move back the
band analysis from...
(gray_cubic_to): ... here.
(gray_move_to): Updated.
2016-05-25 Werner Lemberg <wl@gnu.org>
[autofit] Fixes for Armenian and Gujarati ranges.
* src/autofit/afranges.c (af_armn_uniranges): Corrected.
(af_guru_nonbase_uniranges): Make U+0A3E a base character.
2016-05-24 Werner Lemberg <wl@gnu.org>
[autofit] Add support for Armenian script.
* src/autofit/afblue.dat: Add blue zone data for Armenian.
* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
* src/autofit/afscript.h: Add Armenian standard characters.
* src/autofit/afranges.c: Add Armenian data.
* src/autofit/afstyles.h: Add Armenian data.
2016-05-23 Werner Lemberg <wl@gnu.org>
* builds/unix/unix-cc.in (LINK_LIBRARY): Use `-export-symbols'.
This was commented about 10 years ago – I think the reason then to
disable libtool's `-export-symbols' option was to give some badly
programmed applications access to internal FreeType functions.
I believe that we should no longer take care of such programs; the
number of symbols exported should be rather restricted as much as
possible.
2016-05-22 Werner Lemberg <wl@gnu.org>
[autofit] Add blue-zone support for Gurmukhi script.
This essentially moves the Gurmukhi script from the `Indic' hinter to
the `Latin' hinter.
* src/autofit/afblue.dat: Add blue zone data for Gurmukhi.
* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.

data out of AF_CONFIG_OPTION_INDIC block.
* src/autofit/afranges.c: Move Gurmukhi data out of
AF_CONFIG_OPTION_INDIC block.
* src/autofit/afstyles.h: Update Gurmukhi data; in particular, use
AF_WRITING_SYSTEM_LATIN.
2016-05-21 Werner Lemberg <wl@gnu.org>
Minor clang++ fixes.
* src/base/ftobjs.c (FT_Add_Module), src/psaux/psobjs.c
(ps_parser_load_field), src/type1/t1load.c (parse_subrs): Add
initializer.
* src/cache/ftccache.h (FTC_CACHE_TRYLOOP_END): Avoid implicit
conversion from NULL to boolean.
2016-05-21 Werner Lemberg <wl@gnu.org>
Work around a bug of the C 8.0.0.1 compiler on AIX 5.3 (#47955).
* include/freetype/internal/ftmemory.h (cplusplus_typeof): Use
braces for `extern "C++"'.
2016-05-17 Nikolaus Waxweiler <madigens@gmail.com>
[truetype] Make TT_LOADER_SET_PP support subpixel hinting [3/3].
* src/truetype/ttgload.c (TT_LOADER_SET_PP): Replace macro with...
(tt_loader_set_pp): ... this new function.
Update all callers.
2016-05-17 Nikolaus Waxweiler <madigens@gmail.com>
[truetype] New implementation of v38 bytecode interpreter [2/3].
This patch actually modifies the bytecode interpreter.

* include/freetype/config/ftstdlib.h (FT_LONG_MIN): New macro.
* src/cff/cffparse.c (cff_parse_font_matrix): Use largest scaling
value of all matrix coefficients to scale matrix.
* src/cff/cffobjs.c (cff_face_init): Use `matrix->yx' member for
matrix normalization if `matrix->yy' is zero.
2016-05-16 Werner Lemberg <wl@gnu.org>
[base] Reject invalid sfnt Mac resource (#47891).
* src/base/ftobjs.c (open_face_PS_from_sfnt_stream): Check validity
of `CID ' and `TYPE1' table offset and length.
2016-05-16 Werner Lemberg <wl@gnu.org>

2016-05-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[truetype] Improve the recursive reference detector.
The previous fix for #46372 misunderstood a composite glyph referring
same component twice as a recursive reference. See the discussion
https://lists.gnu.org/archive/html/freetype/2016-05/msg00000.html
Thanks to Khaled Hosny for finding this issue.
* src/truetype/ttgload.c (ft_list_get_node_at): A function to get
the i-th node from FT_List.
(load_truetype_glyph): In the traversal scan of the reference tree
in the composite glyph, we clear the nodes filled by previous
sibling chain.
2016-05-07 Werner Lemberg <wl@gnu.org>
[cache] Allow value 0 for face ID.
We never dereference `face_id', and some implementations might use a
running number instead of a pointer. Additionally, disallowing
value zero was undocumented.
* src/cache/ftccmap.c (FTC_CMapCache_Lookup), src/cache/ftcmanag.c
(FTC_Manager_LookupFace, FTC_Manager_RemoveFaceID): Remove test for
`face_id'.
2016-05-05 Alexei Podtelezhnikov <apodtele@gmail.com>
[smooth] More efficient accounting of conic splits and draws.
A single decrement counter of segments to draw, instead of an array,
contains all the information necessary to decide when to split and
when to draw a conic segment. The number of splits before each draw is
equal to the number of trailing zeros in the counter.
* src/smooth/ftgrays.c (gray_TWorker): Remove `lev_stack'.
(gray_render_conic): Updated to use decrement counter of segments.
2016-05-05 Werner Lemberg <wl@gnu.org>
[cff, truetype] Fix logic for `FT_Property_Set'.
Otherwise some properties could be set to arbitrary values, which is
harmless, but querying could give wrong positive results.
* src/cff/cffdrivr.c (cff_property_set) [hinting-engine],
* src/truetype/ttdriver.c (tt_property_set) [interpreter-version]:
Only allow defined values.
2016-04-25 Werner Lemberg <wl@gnu.org>
[autofit] Add blue-zone support for Gujarati script.
This essentially moves the Gujarati script from the `Indic' hinter to
the `Latin' hinter.
* src/autofit/afblue.dat: Add blue zone data for Gujarati.
* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.

Updated.
* src/autofit/afblue.c: Regenerated.
2016-04-16 David Capello <davidcapello@gmail.com>
[cmake] Honor SKIP_INSTALL_* settings (as used in zlib).
As FreeType depends on zlib, if we don't install zlib (e.g., because
we defined SKIP_INSTALL_ALL), FreeType cannot be installed, too
(cmake triggers an error saying that FreeType cannot be installed
because zlib target isn't in the export set).
* CMakeLists.txt: Honor `SKIP_INSTALL_HEADERS',
`SKIP_INSTALL_LIBRARIES', and `SKIP_INSTALL_ALL' settings.
2016-04-16 Behdad Esfahbod <behdad@behdad.org>
[truetype] Another fix for non-intermediate GX tuples.

* include/freetype/internal/internal.h
[FT_INTERNAL_POSTSCRIPT_GLOBALS_H]: Remove.
2016-04-09 Werner Lemberg <wl@gnu.org>
[autofit] Add support for Georgian scripts.
Georgian is problematic, since `uppercase' forms of Mkhedruli
(called Mtavruli) are not yet defined in Unicode, which means that
proper blue zones can't be defined. However, there is already a
proposal submitted to Unicode; see
https://www.unicode.org/L2/L2016/16034-n4707-georgian.pdf
Additionally, due to historical reasons, Unicode treats Khutsuri as
the same script as Mkhedruli, and so does OpenType. However, since
the two scripts have completely different shapes it can happen that
blue zones differ considerably. The tag `geok' used here (derived
from ISO 15924) to differentiate the two scripts is not an OpenType
tag in use. If we now have a font that contains both glyphs for
Mkhedruli and Khutsuri, and it uses OpenType features for both also,
HarfBuzz unavoidably treats all glyphs as `geor'. As a consequence,
blue zones for `geok' are not used for glyphs involved in the
OpenType features.
An issue not yet resolved is which OpenType feature should be used
to access Mtavruli glyph shapes; right now, FreeType doesn't set up
support for them, but it is easy to add them later on as soon as
more information is available.
* src/autofit/afblue.dat: Add blue zone data for Georgian.
* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
* src/autofit/afscript.h: Add Georgian standard characters.

* src/autofit/afstyles.h: Add Georgian data.
2016-04-05 Werner Lemberg <wl@gnu.org>
[autofit] Provide dummy blue zone for pseudo script `none'.
Even if the dummy hinter is used as the handler for `none' (which
doesn't use blue zones), it is more consistent than the old value
(which was 0), pointing to Arabic...
* src/autofit/afblue.dat: Add `AF_BLUE_STRINGSET_NONE'.
* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
* src/autofit/afstyles.h (none_dflt): Use AF_BLUE_STRINGSET_NONE.

FreeType binary search code.
(pfr_load_bitmap_metrics): Fix invalid left shift.
2016-03-29 Werner Lemberg <wl@gnu.org>
* src/pfr/pfrtypes.h: Replace all enums with macros.
We need `~FOO' to unset bits, and only with unsigned values (which
`enum' isn't normally) this works cleanly.
2016-03-26 Werner Lemberg <wl@gnu.org>
[pfr] Robustify bitmap strike handling (#47514).
We did a binary search for a charcode without ensuring that the
searched data is ordered. Validating the order is now done lazily,
this is, the first access to a bitmap glyph triggers the order check
in the corresponding bitmap strike.
* src/pfr/pfrtypes.h (PFR_BitmapFlags): New values
`PFR_BITMAP_VALID_CHARCODES' and `PFR_BITMAP_CHARCODES_VALIDATED'.
* src/pfr/pfrsbit.c (pfr_lookup_bitmap_data): Make `flags' argument
a pointer. Handle new PFR_BITMAP_XXX flags.

pfr_glyph_load_compound): Use them.
2016-03-25 Werner Lemberg <wl@gnu.org>
[pfr] Minor.

to pass difference between hinted and unhinted position of base
point; use this to adjust the stem width depending on the PPEM so
that it doesn't become too large under certain circumstances.
Update all callers using value 0 for this argument except...
(af_latin_align_linked_edge): Pass position delta of base point to
`af_latin_compute_stem_width'.

[autofit] Properly handle spikes pointing to the x-axis.
An example that gets better rendered is glyph `uusignTaml' (glyph
index 2286) in font `FreeSerif.ttf' (Version 0412.2263) at 22ppem.
* src/autofit/aflatin.c (af_latin_hints_compute_segments): Properly
handle segments where the last point of the first segment is
identical to the first point in the second one. This can happen for
malformed fonts or spikes. We either merge the new segment with the
previous one (both segments point into the same direction), or we
discard the shorter segment if they point into different directions.
2016-02-27 Werner Lemberg <wl@gnu.org>
[autofit] Minor code clean-up.
* src/autofit/aflatin.c (af_latin_hints_compute_segments): Change

[autofit] Improve BOUND action.
In complex glyph shapes, the original logic was too simple to cater
for situations that would actually need something similar to PS Hint
masks. This fix should alleviate the worst cases.

[autofit] Fix handling of default script.
Patch taken from ttfautohint, commit
071ae2c00e0d67f9d19418f4fade1c23d27dc185.
There were two bugs.
- We now use non-standard script tags like `khms' for special
purposes. However, HarfBuzz maps such tags to `DFLT', and
without this commit the associated lookups were incorrectly
assigned to the non-standard tags.
- Let's assume we have a Bengali font, and the font's `DFLT'
script tag handles the necessary lookups for Bengali, too.
Without this commit, the `DFLT' lookups were assigned to
ttfautohint's default script (usually `latn') before the
standard lookups for Bengali were handled.
We now have the following order while searching for covered
glyph indices.
special features of scripts (e.g. `sups' for Cyrillic)
Unicode mappings of scripts
remaining features of scripts (especially important for Indic
scripts)
default features of default script
* src/autofit/afshaper.c, src/autofit/afshaper.h

2015-12-09 Werner Lemberg <wl@gnu.org>
[autofit] Introduce subscript top blue zones.
This feature is mainly for Khmer: The idea is to avoid a clash
between the top of subscript glyphs and the bottom of normal
baseline glyphs.
This only works for character clusters mapped to multiple glyphs.
* src/autofit/afblue.dat: Add subscript top blue zone for Khmer.
* src/autofit/afblue.hin (AF_BLUE_PROPERTY_LATIN_SUB_TOP): New
macro.

2015-12-06 Werner Lemberg <wl@gnu.org>
[autofit] Rewrite HarfBuzz interface to support character clusters.
Scripts like Khmer have blue zones that can't be directly
represented by Unicode characters. Instead, it is necessary to let
HarfBuzz convert character clusters into proper glyph representation
forms, then deriving the blue zone information from the resulting
glyphs.
* src/autofit/hbshim.c, src/autofit/hbshim.h: Replaced by...
* src/autofit/afshaper.c, src/autofit/afshaper.h: ... these two new
files, providing a new API to access HarfBuzz.
The new API manages a HarfBuzz buffer with `af_shaper_buf_create'
and `af_shaper_buf_destroy'. The buffer receives a UTF8 encoded
string with function `af_shaper_get_cluster', and the resulting
glyph data (indices, advance widths, vertical offsets) can be
iteratively accessed with function `af_shaper_get_elem'.
* src/autofit/afcjk.c (af_cjk_metrics_init_widths,
af_cjk_metrics_init_blues, af_cjk_metrics_check_digits): Updated.
* src/autofit/aflatin.c (af_latin_metrics_init_widths,
af_latin_metrics_init_blues, af_latin_metrics_check_digits):

src/autofit/afpic.c, src/autofit/afranges.c, src/autofit/hbshim.c

Instead, reduce multiple spaces to a single one. We need this later
for supporting character clusters in `afblue.dat'.

Currently, libFuzzer only supports mutation of a single file. We
circumvent this problem by using an uncompressed tar archive as

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

[sfnt] Better checks for invalid cmaps (2/2) (#46019).
While the current code in `FT_Get_Next_Char' correctly rejects
out-of-bounds glyph indices, it can be extremely slow for malformed

[sfnt] Improve handling of invalid SFNT table entries (#45987).
This patch fixes weaknesses in function `tt_face_load_font_dir'.
- It incorrectly assumed that valid tables are always at the
beginning. As a consequence, some valid tables after invalid
entries (which are ignored) were never seen.
- Duplicate table entries (this is, having the same tag) were not
rejected.
- The number of valid tables was sometimes too large, leading to
access of invalid tables.
* src/sfnt/ttload.c (check_table_dir): Add argument to return number
of valid tables.
Add another tracing message.
(tt_face_load_font_dir): Only allocate table array for valid
entries as returned by `check_table_dir'.

* src/gzip/ftgzip.c (ft_gzip_stream_close): Avoid memory leak.
(ft_gzip_get_uncompressed_file): Correct byte order while reading

2015-09-04 Werner Lemberg <wl@gnu.org>
[autofit] Redesign code ranges (1/2).
This patch introduces auxiliary code ranges that identify no-base
characters; they refer to glyphs of a script that should be hinted
without alignments to blue zones (mostly diacritics).
It also splits off ranges for fallback scripts that handle subscript
and superscript characters not covered by OpenType features. For
example, this greatly helps improve the hinting of various phonetic
alphabets, which contain a large amount characters that look like
superscript glyphs.
Finally, code ranges are updated to Unicode 8.0, and enclosed
characters are removed in general since they normally look better if
they stay unhinted.
* src/autofit/afranges.c (af_latn_uniranges): Updated to Unicode
8.0.
Split off superscript-like and subscript-like glyphs into...
(af_latb_uniranges, af_latp_uniranges): ... these two new arrays.
(af_xxxx_nobase_uniranges): New arrays that hold no-base characters
of the corresponding character ranges.

[truetype] Introduce named instance access to GX fonts.
For functions querying a face, bits 16-30 of the face index can hold
the named instance index if we have a GX font. The indices start

[builds/unix] Minor.
* builds/unix/configure.raw:
s/lib{priv,staticconf}/libs{priv,staticconf}/ for orthogonality with
similarly named uppercase variables.
2015-08-10 Alexei Podtelezhnikov <apodtele@gmail.com>
[type1,cid,type42] Minor improvements.

[type42] Fix glyph access.
This is a severe bug: We've missed one level of indirection, as
described in the Type 42 specification. As a result, ftview
sometimes showed incorrect glyphs for given glyph names, and even
displayed `error 0x0006' (invalid argument!) in case the number of
glyph indices differed between the Type 42 font and the embedded
TTF.
Apparently, noone ever noticed it; this shows how much Type 42 fonts
are in use...
* src/type42/t42objs.c (T42_GlyphSlot_Load): Map Type 42 glyph index
to embedded TTF's glyph index.
2015-08-08 Werner Lemberg <wl@gnu.org>
[type42] Minor clean-up.
* src/type42/t42parse.c (t42_parse_font_matrix): Remove unused
variable.
2015-08-06 Alexei Podtelezhnikov <apodtele@gmail.com>
[type42] Parse FontMatrix according to specifications.
* src/type42/t42parse.c (t42_parse_font_matrix): Type 42 FontMatrix
does not need scaling by 1000. Units_per_EM are taken from the
embedded TrueType.

[autofit] Improve Arabic hinting.
Problem reported by Titus Nemeth <tn@tntypography.eu> (by using
ttfautohint).
* src/autofit/afblue.dat: Add neutral blue zone for the tatweel
character.
* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
2015-08-05 Alexei Podtelezhnikov <apodtele@gmail.com>
[truetype] Clean up types.
* src/truetype/ttobjs.c (TT_Size): Move declaration from here.
* include/freetype/internal/tttypes.h (TT_Size): ... to here.
(TT_LoaderRec): Switch to appropriate types for `face' and `size'.
* src/truetype/ttgload.c: Remove corresponding type casts.
* src/truetype/ttsubpix.c: Ditto.

[autofit] Improve recognition of flat vs. rounded segments.
Lower the flatness threshold from upem/8 to upem/14, making the
auto-hinter accept shorter elements.
Synchronize flat/round stem selection algorithm with blue zone code.
* src/autofit/aflatin.c (FLAT_THRESHOLD): New macro.
(af_latin_metrics_init_blues): Use it.
(af_latin_hints_compute_segments): Collect information on maximum
and minimum coordinates of `on' points; use this to add a constraint
for the flat/round decision similar to
`af_latin_metrics_init_blues'.
2015-08-04 Werner Lemberg <wl@gnu.org>
Another left-shift bug (#45681).
* src/base/ftobjs.c (IsMacBinary): Only accept positive values for
`dlen'.
2015-08-03 Alexei Podtelezhnikov <apodtele@gmail.com>
[base] Fix `ft_corner_orientation'.
Remove casting from `FT_Long' to `FT_Int' that might change the sign
of the return value and make it faster too.
* src/base/ftcalc.c (ft_corner_orientation): On 32-bit systems, stay
with 32-bit arithmetic when safe. Use plain math on 64-bit systems.
* src/pshinter/pshalgo.c: Remove old unused code.
