[base] Formatting and nanooptimizations.
* src/base/ftcalc.c,
* src/base/fttrigon.c: Revise sign restoration.
2014-12-13 Werner Lemberg <wl@gnu.org>

2014-12-11 Werner Lemberg <wl@gnu.org>
* builds/toplevel.mk (dist): Use older POSIX standard for `tar'.
Apparently, BSD tar isn't capable yet of handling POSIX-1.2001
(contrary to GNU tar), so force the POSIX-1.1988 format.
Problem reported by Stephen Fisher <sfisher@SDF.ORG>.

[gxvalid] Fix a naming convention conflicting with ftvalid.
See previous changeset for otvalid.
* src/gxvalid/{gxvcommn.h, gxvmort.h, gxvmorx.h}: Replace
`valid' by `gxvalid'.
* src/gxvalid/{gxvbsln.c, gxvcommn.c, gxvfeat.c, gxvjust.c,
gxvkern.c, gxvlcar.c, gxvmort.c, gxvmort0.c, gxvmort1.c,
gxvmort2.c, gxvmort4.c, gxvmort5.c, gxvmorx.c, gxvmorx0.c,
gxvmorx1.c, gxvmorx2.c, gxvmorx4.c, gxvmorx5.c, gxvopbd.c,
gxvprop.c, gxvtrak.c}: Replace `valid' by `gxvalid' if
it is typed as GXV_Validator.
2014-12-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[otvalid] Fix a naming convention conflicting with ftvalid.
Some prototypes in ftvalid.h use `valid' for the variables
typed as FT_Validator. Their implementations in src/base/
ftobjs.c and utilizations in src/sfnt/ttcmap.c do similar.
Some macros in otvcommn.h assume the exist of the variable
`valid' typed as OTV_Validator in the caller.
Mixing these two conventions cause invalid pointer conversion
and unexpected SEGV in longjmp. To prevent it, all variables
typed as OTV_Validator are renamed to `otvalid'.
* src/otvalid/otvcommn.h: Replace `valid' by `otvalid'.
* src/otvalid/{otvcommn.c, otvbase.c, otvgdef.c, otvgpos.c,
otvgsub.c, otvjstf.c, otvmath.c}: Replace `valid' by `otvalid'
if it is typed as OTV_Validator.
2014-12-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>

* src/gxvalid/gxvcommn.h: Ditto.
* src/otvalid/otvcommn.h: Ditto.
2014-12-08 Werner Lemberg <wl@gnu.org>
[pcf] Fix Savannah bug #43774.
Work around `features' of X11's `pcfWriteFont' and `pcfReadFont'
functions. Since the PCF format doesn't have an official
specification, we have to exactly follow these functions' behaviour.
The problem was unveiled with a patch from 2014-11-06, fixing issue
#43547.
* src/pcf/pcfread.c (pcf_read_TOC): Don't check table size for last
element. Instead, assign real size.
2014-12-07 Werner Lemberg <wl@gnu.org>

* include/internal/ftvalid.h (FT_ValidatorRec), src/smooth/ftgrays.c
(gray_TWorker_): Move `ft_jmp_buf' field to be the first element.
2014-12-07 Werner Lemberg <wl@gnu.org>

2014-12-07 Werner Lemberg <wl@gnu.org>
[truetype] Prevent memory leak for buggy fonts.
* src/truetype/ttobjs.c (tt_size_done): Unconditionally call
`tt_size_done_bytecode'.

docs/CHANGES: Updated, formatted.
2014-12-04 Dave Arnold <darnold@adobe.com>
[cff] Modify an FT_ASSERT.
* src/cff/cf2hints.c (cf2_hintmap_map): After the fix for Savannah
bug #43661, the test font `...aspartam.otf' still triggers an
FT_ASSERT. Since hintmap still works with count==0, ...
(cf2_glyphpath_lineTo, cf2_glyphpath_curveTo): ... add that term to
suppress the assert.
2014-12-04 Dave Arnold <darnold@adobe.com>
[cff] Fix Savannah bug #43661.
* src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdHSTEM,
cf2_cmdVSTEM, cf2_cmdHINTMASK>: Don't append to stem arrays after
hintmask is constructed.
* src/cff/cf2hints.c (cf2_hintmap_build): Add defensive code to
avoid reading past end of hintmask.

docs/CHANGES: Updated.
2014-12-03 Werner Lemberg <wl@gnu.org>
[autofit] Better fix for conversion specifiers in debug messages.
Using `%ld' for pointer differences causes warnings on 32bit
platforms. The correct type would be (the relatively new) `%td',
however, this is missing on some important platforms.
This patch improves the change from 2014-11-28.
* src/autofit/afhints.c (AF_INDEX_NUM): Use `int' typecast. Our
pointer differences are always sufficiently small.
(af_glyph_hints_dump_points, af_glyph_hints_dump_segments,
af_glyph_hints_dump_edge): Revert to `%d' and use `AF_INDEX_NUM'.
2014-12-03 Werner Lemberg <wl@gnu.org>
FT_Sfnt_Tag: s/ft_sfnt_xxx/FT_SFNT_XXX/ for orthogonality.
All public FreeType enumeration and flag values are uppercase...
* include/tttables.h (FT_Sfnt_Tag): Implement it. For backward
compatibility, retain the old values as macros.
* src/base/ftfstype.c (FT_Get_FSType_Flags), src/sfnt/sfdriver.c
(get_sfnt_table): Updated.
2014-12-02 Werner Lemberg <wl@gnu.org>
* include/*: Improve structure of documentation.
. Add and update many `<Order>' tags.
. Apply various documentation fixes.
. Remove details to deprecated (or never implemented) data.
2014-12-02 Werner Lemberg <wl@gnu.org>
[docmaker] Always handle `<Order>' section elements.
Previously, those elements were handled only for sections present in
a `<Sections>' chapter element.
* src/tools/docmaker/content.py (ContentProcessor::finish):
Implement it.
2014-12-02 Werner Lemberg <wl@gnu.org>
[docmaker] Properly handle empty rows in Synopsis.
* src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Emit
`&nbsp;' for empty fields.
2014-12-02 Werner Lemberg <wl@gnu.org>
[docmaker] Thinko.
* src/tools/docmaker/content.py (DocBlock::get_markup_words_all):
Emit `/empty/' string for first element also.
2014-12-02 Werner Lemberg <wl@gnu.org>
[docmaker] Honour empty lines in `<Order>' section element.
This greatly improves the readability of the `Synopsis' links.
* src/tools/docmaker/content.py (DocBlock::get_markup_words_all):
Insert string `/empty/' between items.
* src/tools/docmaker/formatter.py (Formatter::section_dump): Make it
robust against nonexistent keys.
* src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Emit
empty <td> elements for `/empty/'.
2014-12-02 Werner Lemberg <wl@gnu.org>
[docmaker] Ensure Python 3 compatibility.
* src/tools/docmaker/content.py (ContentProcessor::set_section,
ContentProcessor::finish): Replace `has_key' function with `in'
keyword.

keyword.
* src/tools/docmaker/tohtml.py (HtmlFormatter::html_source_quote):
Replace `has_key' function with `in' keyword.
(HtmlFormatter::index_exit, HtmlFormatter::section_enter): Use
integer division.
s/<>/>/.
* src/tools/docmaker/utils.py: Import `itertools'.
(index_sort): Replaced by...
(index_key): ... this new key generator (doing exactly the same).
2014-11-29 Werner Lemberg <wl@gnu.org>
[docmaker] Don't output a block multiple times.
This bug was hidden by not processing all lines of `<Order>' blocks.
* src/tools/docmaker/formatter.py (Formatter::section_dump): Filter
out field names.
2014-11-29 Werner Lemberg <wl@gnu.org>
[docmaker] Use field values as HTML link targets where possible.
* src/tools/docmaker/tohtml.py (HtmlFormatter::make_block_url):

(HtmlFormatter::html_source_quote): Link to field ID if possible.
(HtmlFormatter::print_html_field_list): Emit `id' attribute.
2014-11-29 Werner Lemberg <wl@gnu.org>
[docmaker] Allow empty lines in `<Order>' blocks.
Before this patch, the suggested order of entries stopped at the
first empty line.
Obviously, nobody noticed that this problem caused a much reduced
set of links in the `Synopsis' sections; in particular, the
`<Order>' blocks contain a lot of entries that wouldn't be listed
otherwise...
* src/tools/docmaker/content.py (DocBlock::get_markup_words_all):
New function to iterate over all items.
(DocSection::process): Use it.
2014-11-29 Werner Lemberg <wl@gnu.org>
* src/tools/docmaker/sources.py (column) [Format 2]: Fix regexp.
After the single asterisk there must be no other immediately following
asterisk.
2014-11-29 Werner Lemberg <wl@gnu.org>

* src/tools/docmaker/tohtml.py: Introduce a new table class `toc',
together with proper CSS.
2014-11-29 Werner Lemberg <wl@gnu.org>
[docmaker] Provide higher-level markup and simplify HTML.
* src/tools/docmaker/tohtml.py: Instead of using extraneous `<div>'
elements, use CSS descendants (of class `section') to format the
data.
Also remove redundant <p> and <br> elements, replacing them with
proper CSS.
Globally reduce page width to 75%.
(block_header): Rename <div> class to `section'.
2014-11-29 Werner Lemberg <wl@gnu.org>
[docmaker] Add `top' links after blocks.
* src/tools/docmaker/tohtml.py (block_footer_middle): Implement it.
2014-11-29 Werner Lemberg <wl@gnu.org>

Make fields align horizontally relative to full line width.
2014-11-29 Werner Lemberg <wl@gnu.org>
* src/tools/docmaker/tohtml.py: Fix index and TOC templates.
This thinko was introduced 2014-11-27.
2014-11-28 Werner Lemberg <wl@gnu.org>
[docmaker] Format field lists with CSS.
This also simplifies the inserted HTML code.
* src/tools/docmaker/tohtml.py
(HtmlFormatter::print_html_field_list): Do it.
2014-11-28 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Fix compiler warning to the comparison between signed and
unsigned variable.
* src/pfr/pfrsbit.c (pfr_slot_load_bitmap): Fix the comparison
between `ypos + ysize' and FT_INT_{MAX,MIN}.
2014-11-28 Werner Lemberg <wl@gnu.org>
[docmaker] Replace empty `<td>' with CSS.
* src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Do
it.
2014-11-28 Werner Lemberg <wl@gnu.org>
[docmaker] Replace some `<table>' tags with `<h4>' and `<div>'.
* src/tools/docmaker/tohtml.py (marker_*): Use `<h4>'.
(source_*): Use `<div>'.
(HtmlFormatter::block_enter): s/<h4>/<h3>/.
2014-11-28 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Fix compiler warning to conversion specifiers in debug messages.
* src/autofit/afhints.c (af_glyph_hints_dump_points): Add length
modifier to dump long integers.
(af_glyph_hints_dump_segments, af_glyph_hints_dump_edges): Ditto.
2014-11-27 Werner Lemberg <wl@gnu.org>
* src/tools/docmaker/tohtml.py: Use more CSS for index.
2014-11-27 Werner Lemberg <wl@gnu.org>
[docmaker] Replace `name' attribute of `<a>' with `id'.
* src/tools/docmaker/tohtml.py (HtmlFormatter::block_enter): Do it.
2014-11-27 Werner Lemberg <wl@gnu.org>
* src/tools/docmaker/tohtml.py: Remove remaining `width' attributes.
For `Index' and `TOC' links, we now simply use the `text-align' CSS
property of `<td>' to enforce flush-left and flush-right,
eliminating the hack with an empty, full-width `<td>' element
inbetween.
The change also enforces the same (smaller) size for all index and
TOC links.
2014-11-27 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* src/cff/cf2font.c: Include `ftcalc.h' to use FT_MSB(),
cf2font.c could not find it under `make multi' build.
2014-11-27 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* src/smooth/ftsmooth.c (ft_smooth_render_generic): Remove
unrequired negative value check for `width' and `height'.
2014-11-27 Werner Lemberg <wl@gnu.org>
* src/tools/docmaker/tohtml.py: More HTML table refactoring.
Replace some `<table>' tags with `<div>' to simplify structure.
Move `bgcolor' attribute to CSS.
Replace most `width' attributes with CSS. The remaining instances
(providing a similar effect as LaTeX's `\hfill' command) are removed
in a later patch.
2014-11-27 Werner Lemberg <wl@gnu.org>
* src/tools/docmaker/tohtml.py: Replace <font> with CSS.
2014-11-27 Werner Lemberg <wl@gnu.org>
* src/tools/docmaker/tohtml.py: Center <table> with CSS.
2014-11-27 Werner Lemberg <wl@gnu.org>
* src/tools/docmaker/tohtml.py: Replace `<center>' with `<div>'.
2014-11-27 Werner Lemberg <wl@gnu.org>
* src/tools/docmaker/tohtml.py: Remove redundant `<center>' tags.
This starts a series of commits into the direction of generating
valid HTML 5 code, especially using much more CSS.
2014-11-27 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Prevent too negative values (< FT_INT_MIN) in bitmap metrics,
suggested by Alexei.
* src/pfr/pfrsbit.c (pfr_slot_load_bitmap): Prevent too
negative values in `xpos' and `ypos + ysize'.
* src/smooth/ftsmooth.c (ft_smooth_render_generic): Prevent
too negative values in `x_left' and `y_top'. Either negative
values in `width' and `height' are checked.
2014-11-27 Werner Lemberg <wl@gnu.org>
[docmaker] Produce better HTML code.
* src/tools/docmaker/tohtml.py: Always use double quotes for
attribute values.
(source_footer): Close `td' and `tr' groups.
2014-11-27 Werner Lemberg <wl@gnu.org>

[cff, pfr, psaux, winfonts] Fix Savannah bug #43676.
Don't cast cmap init function pointers to an incompatible type.
Without this patch, the number of parameters between declaration and
the real signature differs. Calling such a function results in
undefined behavior.
ISO/IEC 9899:TC3 (Committee Draft September 7, 2007)
6.5.2.2 Function calls
9 If the function is defined with a type that is not
compatible with the type (of the expression) pointed to by
the expression that denotes the called function, the
behavior is undefined.
On certain platforms (c -> js with emscripten) this causes
termination of execution or invalid calls because in the emscripten
implementation, function pointers of different types are stored in
different pointer arrays. Incorrect pointer type here results in
indexing of an incorrect array.
* src/cff/cffcmap.c (cff_cmap_encoding_init, cff_cmap_unicode_init),
src/pfr/pfrcmap.c (pfr_cmap_init), src/psaux/t1cmap.c

array.
2014-11-22 Werner Lemberg <wl@gnu.org>
[type42] Fix Savannah bug #43659.
* src/type42/t42objs.c (T42_Open_Face): Initialize `face->ttf_size'.
* src/type42/t42parse.c (t42_parse_sfnts): Always set
`face->ttf_size' directly. This ensures a correct stream size in
the call to `FT_Open_Face', which follows after parsing, even for
buggy input data.
Fix error messages.
2014-11-22 Werner Lemberg <wl@gnu.org>
[cff] Fix Savannah bug #43658.
* src/cff/cf2ft.c (cf2_builder_lineTo, cf2_builder_cubeTo): Handle

Fix thinko.
2014-11-19 Alexei Podtelezhnikov <apodtele@gmail.com>
* src/base/fttrigon.c: Use dedicated `FT_Angle' for arctan table.
2014-11-19 Behdad Esfahbod <behdad@behdad.org>
Avoid compiler warnings on x86-64 for `FT_MulFix'.
`FT_MulFix' takes `FT_Long' parameters as defined in `freetype.h',
but several inline implementations of it in `ftcalc.h' take
`FT_Int32' arguments. This is causing compiler warnings on x86-64:
If parameters of type `FT_Fixed' (= `FT_Long') are passed to the
inline implementation of this function, integer values are truncated
from 64bit to 32bit.
* include/internal/ftcalc.h (FT_MulFix) [FT_MULFIX_ASSEMBLER]: Add
casts.
2014-11-15 Werner Lemberg <wl@gnu.org>

against overflow in additions and multiplications.
2014-11-10 Alexei Podtelezhnikov <apodtele@gmail.com>
[base] CORDIC improvements.
The scaling between the hypotenuse and its CORDIC approximation is
based on regression analysis. The smaller padding for `theta' is
justified by its maximum error of less than 6.
* src/base/fttrigon.c (ft_trig_downscale): Borrow code from
./ftcalc.c (ft_multo64), change linear intercept.
(ft_trig_pseudo_polarize): Decrease `theta' padding.

2014-11-03 Infinality <infinality@infinality.net>
* src/truetype/ttsubpix.c (COMPATIBILITY_MODE_Rules): Updated.
The previous commit deteriorates rendering of DejaVu and similar
fonts; this gets compensated with this rule.
2014-11-03 Werner Lemberg <wl@gnu.org>
* src/truetype/ttinterp.c (Ins_DELTAP): Fix subpixel hinting.
Before this patch, it was impossible to ever call DELTAP[123] in
subpixel hinting mode as described in the ClearType whitepaper; it
only worked if in `compatibility mode'. However, compatibility mode
essentially disables SHPIX, completely ruining hinting of
ttfautohint output, for example.
We now follow the whitepaper more closely so that DELTAP[123]
instructions for touched points in the non-subpixel direction are
executed.

specifications and check the sign as the very last step of rounding.
* src/truetype/ttinterp.c (Round_None, Round_To_Grid,
Round_Down_To_Grid, Round_Up_To_Grid, Round_To_Double_Grid): Use
macros when available, do not check for non-zero distance.

[base] Significant optimization of `ft_div64by32'
We shift as many bits as we can into the high register, perform
32-bit division with modulo there, then work through the remaining
bits with long division. This optimization is especially noticeable

[autofit] Fix Savannah bug #42148.
The adaptation of the cjk auto-hinter module to blue stringsets in
2013-08-25 had three severe bugs. Mea culpa.
1. Contrary to the latin auto-hinter, characters for reference and
overshoot values of a blue zone are specified separately. Due to
the screwed-up change it didn't work at all.
2. A boolean comparison was erroneously replaced with a cast,
causing invalid results with the `^' operator later on. The
visual artifact caused by this problem is the topic of the bug
report.
3. Two flag values were inverted, causing incorrect assignment of
reference and overshoot values.
* src/autofit/afblue.dat: Fix CJK bluestrings, introducing a new
syntax to have both reference and overshoot characters in a single
string. This is error #1.
Add extensive comments.
* src/autofit/afblue.hin (AF_BLUE_PROPERTY_CJK_FILL): Removed, no
longer used.
(AF_BLUE_PROPERTY_CJK_TOP, AF_BLUE_PROPERTY_CJK_HORIZ): Fix values.
This is error #3.
* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
* src/autofit/afcjk.c (af_cjk_metrics_init_blues): Correct error #1.
Use character `|' to separate characters for reference and overshoot
values.
Improve tracing messages, synchronizing them with the latin
auto-hinter.
(af_cjk_hints_compute_blue_edges): Fix value of `is_top_right_blue'.
This is error #2.
(af_cjk_align_linked_edge): Add tracing message.
* src/autofit/afcjk.h (AF_CJK_IS_FILLED_BLUE): Removed, no longer
used.

2014-04-12 Werner Lemberg <wl@gnu.org>
[autofit] Redesign the recognition algorithm of strong points.
In particular, local extrema without horizontal or vertical segments
are better recognized:
+ A + D
\ /
\ /
\ /
\ /
\ + C
\ /
B +/
If the distances AB and CD are large, point B wasn't previously
detected as an extremum since the `ft_corner_is_flat' function
`swallowed' BC regardless of its direction, tagging point B as weak.
The next iteration started at B and made `ft_corner_is_flat' swallow
point C, tagging it as weak also, et voilà.
To improve that, another pass gets now performed before calling
`ft_corner_is_flat' to improve the `topology' of an outline: A
sequence of non-horizontal or non-vertical vectors that point into
the same quadrant are handled as a single, large vector.
Additionally, distances of near points are now accumulated, which
makes the auto-hinter handle them as if they were prepended to the
next non-near vector.
This generally improves the auto-hinter's rendering results.
* src/autofit/afhints.c (af_glyph_hints_reload): Implement it.
* src/autofit/afhints.h (AF_FLAGS): Remove no longer used flag
`AF_FLAG_NEAR'.
2014-04-05 Werner Lemberg <wl@gnu.org>
[autofit] Improve scoring algorithm for identifying stems.
Problem reported by Karsten Lücke <karsten.luecke@kltf.de>.
The new algorithm takes care of the width of stems: If the distance
between two segments is larger than the largest stem width, the
demerits quickly increase for larger distances. This improves
hinting of slanted fonts (especially if the inner parts of serifs
have non-horizontal `shoulders'), avoiding false stem links.
* src/autofit/aflatin.c (af_latin_hints_link_segments): Use largest
stem width (if available) to compute better demerits for distances
between stems.
(af_latin_hints_detect_features): Pass stem width array and array
size.
(af_latin_metrics_init_widths): Updated to use original algorithm.
(af_latin_hints_apply): Updated to use new algorithm.

* src/cff/cf2ft.c (cf2_initLocalRegionBuffer,
cf2_initGlobalRegionBuffer): It is possible for a charstring to call
a subroutine if no subroutines exist. This is an error but should
not trigger an assert. Split the assert to account for this.

[cff] Fix Savannah bug #41697, part 1.
* src/cff/cf2hints.c (cf2_hintmap_build): Return when `hintMask' is
invalid. In this case, it is not safe to use the length of
`hStemHintArray'; the exception has already been recorded in
`hintMask'.

2014-02-26 Werner Lemberg <wl@gnu.org>
[bdf] Fix Savannah bug #41692.
bdflib puts data from the input stream into a buffer in chunks of
1024 bytes. The data itself gets then parsed line by line, simply
increasing the current pointer into the buffer; if the search for
the final newline character exceeds the buffer size, more data gets
read.
However, in case the current line's end is very near to the buffer
end, and the keyword to compare with is longer than the current
line's length, an out-of-bounds read might happen since `memcmp'
doesn't stop properly at the string end.
* src/bdf/bdflib.c: s/ft_memcmp/ft_strncmp/ to make comparisons
stop at string ends.

2014-01-26 Werner Lemberg <wl@gnu.org>
[autofit] Introduce two more slots for standard characters.
This is useful for OpenType features like `c2sc' (caps to small

[autofit] Fix Indic scripts.
Split the single, incorrect Indic entry into separate scripts so
that the covered ranges are the same: Bengali, Devanagari, Gujarati,
Gurmukhi, Kannada, Limbu, Malayalam, Oriya, Sinhala, Sundanese,
Syloti Nagri, Tamil, Telugu, and Tibetan. At the same time, remove
entries for Meetei Mayek and Sharada – the Unicode ranges were
incorrect (and nobody has complained about that), fonts are scarce
for those scripts, and the Indic auto-hinter support is rudimentary
anyways.
* src/autofit/afscript.h: Updated, using AF_CONFIG_OPTION_INDIC and
AF_CONFIG_OPTION_CJK.
* src/autofit/afstyles.h (STYLE_DEFAULT_INDIC): New auxiliary macro.
Use it, together with AF_CONFIG_OPTION_INDIC and
AF_CONFIG_OPTION_CJK, to update.
* src/autofit/afranges.c [AF_CONFIG_OPTION_INDIC]: Updated.
[!AF_CONFIG_OPTION_INDIC, !AF_CONFIG_OPTION_CJK]: Removed.

[autofit] Fix handling of default coverages.

auxiliary macros; use them to define styles for Cyrillic, Greek, and
Latin.
* src/autofit/afcover.h: Remove coverage for oldstyle figures.
Since those digits are used in combination with ordinary letters, it
makes no sense to handle them separately.

2013-12-30 Werner Lemberg <wl@gnu.org>
[autofit] Don't combine multiple features into one set.
Combining them, as originally envisioned, would lead to much more
complicated code, as investigations have shown meanwhile. The major
drawback is that we run out of available style slots much earlier.
However, this is only a theoretical issue since we don't support a
large number of scripts currently.
* src/autofit/afcover.h: Replace `COVERAGE_{1,2,3}' macros with
a single-element `COVERAGE' macro, sort the elements by the feature
tags, and add entry for `ruby'.
* src/autofit/aftypes.h: Updated.
* src/autofit/hbshim.c: Updated.

headers.

[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.

[autofit] Introduce `coverages'.
Coverages are the interface to the HarfBuzz library to access
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

* src/truetype/ttgload.c (TT_Hint_Glyph): Horizontal phantom points
are rounded horizontally, vertical ones are rounded vertically.

points in pre-ClearType mode is zero, as shown in the OpenType
specification.
2013-12-02 Werner Lemberg <wl@gnu.org>
[truetype] Fix change from 2013-11-20.
Problem reported by Akira Kakuto <kakuto@fuk.kindai.ac.jp>.
* src/truetype/ttgload.c (TT_Load_Simple_Glyph): Protect call to
`Update_Max' with both a TT_USE_BYTECODE_INTERPRETER guard and a
`IS_HINTED' clause.
Also remove redundant check using `maxSizeOfInstructions' – in
simple glyphs, the bytecode data comes before the outline data, and
a validity test for this is already present.

default values.
2013-11-13 Werner Lemberg <wl@gnu.org>
* builds/unix/ft2unix.h: Remove. No longer necessary.
* builds/unix/install.mk (install): Updated.
2013-11-13 Werner Lemberg <wl@gnu.org>
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
