[ftrfork] Fix the face order difference between POSIX and Carbon.
The fragmented resources in Suitcase and .dfont should be reordered
when `POST' resource for Type1 is being restored, but reordering of
sfnt resources induces the different face order. Now the ordering
is restricted to `POST' resource only, to prevent the different
order issue (e.g. the face index in the fontconfig cache generated
with Carbon framework is incompatible with that by FreeType 2
without Carbon framework.) Found by Khaled Hosny and Hin-Tak Leung.

2013-12-21 Werner Lemberg <[email protected]>
[autofit] Introduce `coverages'.
Coverages are the interface to the HarfBuzz library to acces
OpenType features for handling glyphs not addressable by the cmap.
Right now, compilation of HarfBuzz is only added to the development
build. A solution for standard build mode will be delayed until
HarfBuzz gets split into two libraries to avoid mutual dependencies
between FreeType and HarfBuzz.
Note that this is only a first step in handling coverages, basically
providing the framework only. Code for handling selected OpenType
features (this is, actually using the data in `afcover.h') will
follow.
* devel/ftoption.h, include/config/ftoption.h
(FT_CONFIG_OPTION_USE_HARFBUZZ): New macro.

data.
* src/autofit/afglobal.h: Update use of `SCRIPT' and `STYLE' macros.

(AF_STYLE_FALLBACK): ... this.
* src/autofit/afglobal.c: Include `hbshim.c'.
Update use of `SCRIPT' and `STYLE' macros.
(af_face_globals_compute_style_coverage)
[FT_CONFIG_OPTION_USE_HARFBUZZ]: Call `af_get_coverage'.
Update.
* src/autofit/afmodule.h (AF_ModuleRec):
s/fallback_script/fallback_style/.
* src/autofit/afmodule.c (af_property_set): Adapt handling of

generated function name.
* src/base/basepic.c (FT_Init_Table_raccess_guess_table): Rename
to ...
(FT_Init_Table_ft_raccess_guess_table): ... this so that the
function name correctly corresponds to what the macro framework
expects.

and BSB.
2013-12-05 Werner Lemberg <[email protected]>

* src/truetype/ttgload.c (TT_Hint_Glyph): Horizontal phantom points
are rounded horizontally, vertical ones are rounded vertically.
(TT_LOADER_SET_PP): The horizontal position of vertical phantom
points in pre-ClearType mode is zero, as shown in the OpenType
specification.
2013-12-02 Werner Lemberg <[email protected]>

simple glyphs, the bytecode data comes before the outline data, and
a validity test for this is already present.

* src/sfnt/ttsbit.c (tt_sbit_decoder_load_bitmap): Don't trust glyph
format.
2013-11-20 Werner Lemberg <[email protected]>

http://lists.nongnu.org/archive/html/freetype-devel/2013-08/msg00005.html
for details.
* src/base/ftobjs.c (FT_Load_Glyph): Check size of `fpgm' and `prep'
tables also for setting `autohint'.

OpenType mailing list, which unfortunately hasn't a public archive).
* include/freetype/tttables.h (TT_OS2):
s/usLowerPointSize/usLowerOpticalPointSize/,
s/usUpperPointSize/usUpperOpticalPointSize/.
* src/sfnt/ttload.c (tt_face_load_os2): Update, and set correct
default values.
2013-11-13 Werner Lemberg <[email protected]>
* builds/unix/ft2unix.h: Remove. No longer necessary.
* builds/unix/install.mk (install): Updated.
2013-11-13 Werner Lemberg <[email protected]>
Simplify header file hierarchy.
This large patch changes the header file directory layout from
`include/freetype/...' to `include/...', effectively removing one
level. Since the file `ft2build.h' is also located in `include'
(and it stays there even after installation), all FreeType header
files are now in a single directory.
Applications that use (a) `freetype-config' or FreeType's
`pkg-config' file to get the include directory for the compiler, and
(b) the documented way for header inclusion like
#include <ft2build.h>
#include FT_FREETYPE_H
...
don't need any change to the source code.
* include/freetype/*: Move up to...
* include/*: ... this directory.
* builds/amiga/include/freetype/*: Move up to...
* builds/amiga/include/*: ... this directory.
*/*: Essentially do `s@/freetype/@/@' where appropriate.
* CMakeList.txt: Simplify.
* builds/unix/freetype-config.in, builds/unix/freetype2.in: For
`--cflags', return a single directory.
* builds/unix/install.mk (install): No longer try to remove `cache'
and `internal' subdirectories; instead, remove the `freetype'
subdirectory.
2013-11-12 Werner Lemberg <[email protected]>
[truetype] Fix last `truetype' commit.

`yMax' value. Replace code with fixed Microsoft definition.
(tt_get_metrics): Updated.
(TT_LOADER_SET_PP): Add explanation how to initialize phantom
points, taken from both the OpenType specification and private

[truetype] Minor code refactoring.
Two benefits: The allocated FDEF (and IDEF) array gets slightly
smaller, and the `ttdebug' demo program has access to function
numbers without additional costs.
Fortunately, no changes to FontForge are necessary – this is the
only external TrueType debugger I know of, but others may exist and
should check the code accordingly.

* src/cff/cf2font.c (cf2_computeDarkening): Avoid division by zero.
Note that the old code avoided using a region of the piecewise
linear function where the slope was zero. The recovery was to use a
different section of the function, which produced a different,
incorrect amount of darkening.

2013-10-02 Dave Arnold <[email protected]>
* src/cff/cf2font.c (cf2_computeDarkening): Initialize darkenAmount.
This line was lost in commit 89ca1fd6 (from 2013-06-25). The effect
is to use a previous darkening amount when producing an unhinted,
unscaled outline. This can cause autohint samples in ftgrid and
ftview to be based on darkened CFF outlines instead of unhinted,
undarkened ones.
2013-09-29 Dave Arnold <[email protected]>
Fix Savannah bug #39295.
The bug was caused by switching to the initial hintmap (the one in
effect when `moveto' executes) just before drawing the final element
in the charstring. This ensured that the path was closed (in both
Character Space and Device Space). But if the final element was a
curve and if the final hintmap was different enough from the initial
one, then the curve was visibly distorted.
The first part of the fix is to draw the final curve using the final
hintmap as specified by the charstring. This corrects the
distortion but does not ensure closing in Device Space. It may
require the rasterizer to automatically generate an extra closing
line. Depending on the hintmap differences, this line could be from
zero to a couple pixels in length.
The second part of the fix covers the case where the charstring
subpath is closed with an explicit line. We now modify that line's
end point to avoid the distortion.
Some glyphs in the bug report font (TexGyreHeros-Regular) that show
the change are:
25ppem S (98)
24ppem eight (52)
25.5ppem p (85)
Curves at the *end* of a subpath are no longer distorted. However,
some of these glyphs have bad hint substitutions in the middle of a
subpath, and these are not affected.
The patch has been tested with a set of 106 fonts that shipped with
Adobe Creative Suite 4, together with 756 Open Source CFF fonts from
Google Fonts. There are 1.5 million glyphs, of which some 20k are
changed with the fix. A sampling of a few hundred of these changes
have been examined more closely, and the changes look good (or at
least acceptable).
* src/cff/cf2hints.h (CF2_GlyphPathRec): New element `pathIsClosing'
to indicate that we synthesize a closepath line.
* src/cff/cf2hints.c (cf2_glyphpath_init): Updated.
(cf2_glyphpath_pushPrevElem): If closing, use first hint map (for
`lineto' operator) and adjust hint zone.
For synthesized closing lines, use end point in first hint zone.
(cf2_glyphpath_lineTo): Take care of synthesized closing lines. In
particular, shift the detection of zero-length lines from character
space to device space.
(cf2_glyphpath_closeOpenPath): Remove assertion.
Updated.

[autofit] Introduce data file for blue strings.
The idea is to have a central file which gets processed by a Perl
script to create proper `.c' and `.h' files using templates. There
are two other reasons to do that:
. The data file should be easily readable. We use UTF-8 encoding
which then gets converted to single bytes.
. Since the number of supported scripts will increase soon, the
current usage of blue string arrays is a waste of space. Using
the Perl script it is possible to imitate jagged arrays,
defining enumeration constants as offsets into the arrays.
This commit only adds files without changing any functionality.
* src/autofit/afblue.dat: New data file.
* src/tools/afblue.pl: New Perl script for processing `afblue.dat'.
* src/autofit/afblue.cin, src/autofit/afblue.hin: New template files

[autofit] Improve handling of `near' points.
Points which are very near to each other are now marked as such.
The `weak' flag is then computed by using the `in' vector of the
first and the `out' vector of the last point of a group of near

For example, this fixes the rendering of glyph `Oslash' in
`Roboto-Thin.ttf'.

* src/autofit/afhints.c (af_glyph_hints_reload): Introduce
the heuristic value `near_limit' to decide whether the current point
is near to the previous one, then set `AF_FLAG_NEAR' accordingly.
Store good `in' vector (of last non-near point) in

[autofit] Introduce `writing systems'.
This patch adds a new top level to the auto-hinter's script class
hierarchy. It defines `writing systems' which can contain multiple

can be handled similarly.
Scripts are now named using four-letter OpenType tags.

Speed up ARMv7 support.
When building for ARMv7 with thumb2 instructions, the optimized
`FT_MulFix_arm' assembly routine was not being used.
The reason for this is in the `ftconfig.h' header, namely:
- The assembly routine uses the `smull' instruction which is not
available when generating Thumb-1 machine code. It is available
in Thumb-2 mode, though.
- The header was written a long time ago before Thumb-2 became
widely popular (e.g. with Android). So it simply doesn't use the
assembly routine if the `__thumb__' built-in macro is defined.
- When compiling in Thumb-2 mode, the compiler will define both
`__thumb__' and `__thumb2__'.
By checking for `(__thumb2__ || !__thumb__)', we ensure that the
assembly routine is only avoided when generating Thumb-1 code.
Given that this is performance-sensitive function, this improves
`ftbench' as follows on a Galaxy Nexus:

2013-06-04 Werner Lemberg <[email protected]>
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.
* src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt1_entry_validate):
Remove functionless code.
* src/tools/ftrandom.c (main): Fix memory leak.
2013-06-03 Werner Lemberg <[email protected]>
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),
src/cff/cffgload.h, src/cff/cffobjs.c (cff_driver_init): Use
CFF_CONFIG_OPTION_OLD_ENGINE to guard the affected code.
* docs/CHANGES: Updated.
2013-06-02 Werner Lemberg <[email protected]>

* builds/unix/configure.raw: Don't use LIBPNG_LIBS but
LIBPNG_LDFLAGS.
2013-05-23 Behdad Esfahbod <[email protected]>
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.
Add `--without-png' option.
