2014-12-30 Werner Lemberg <wl@gnu.org>
* Version 2.5.5 released.
=========================
Tag sources with `VER-2-5-5'.
* docs/VERSION.DLL: Update documentation and bump version number to
2.5.5.

* include/freetype/freetype.h (FREETYPE_PATCH): Set to 5.
* builds/unix/configure.raw (version_info): Set to 17:4:11.
* CMakeLists.txt (VERSION_PATCH): Set to 5.
* docs/CHANGES: Updated.
2014-12-24 Alexei Podtelezhnikov <apodtele@gmail.com>
[base] Formatting and nanooptimizations.
* src/base/ftcalc.c,
* src/base/fttrigon.c: Revise sign restoration.
2014-12-13 Werner Lemberg <wl@gnu.org>
* src/pcf/pcfread.c (pcf_read_TOC): Improve fix from 2014-12-08.
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>.
2014-12-11 Werner Lemberg <wl@gnu.org>
* src/type42/t42parse.c (t42_parse_sfnts): Reject invalid TTF size.
2014-12-11 Werner Lemberg <wl@gnu.org>
* src/base/ftobjs.c (FT_Get_Glyph_Name): Fix off-by-one check.
Problem reported by Dennis Felsing <dennis@felsin9.de>.
2014-12-11 Werner Lemberg <wl@gnu.org>
* src/type42/t42parse.c (t42_parse_sfnts): Check `string_size'.
Problem reported by Dennis Felsing <dennis@felsin9.de>.
2014-12-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[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>
[ftvalid] Introduce FT_THROW() in FT_INVALID_XXX macros.
Original patch is designed by Werner Lemberg. Extra part
for otvalid and gxvalid are added by suzuki toshiya, see
discussion:
http://lists.nongnu.org/archive/html/freetype-devel/2014-12/msg00002.html
http://lists.nongnu.org/archive/html/freetype-devel/2014-12/msg00007.html
* include/internal/ftvalid.h: Introduce FT_THROW() in FT_INVALID_().
* 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>
Work around a bug in Borland's C++ compiler.
See
http://qc.embarcadero.com/wc/qcmain.aspx?d=118998
for Borland's bug tracker entry.
Reported by Yuliana Zigangirova <zigangirova@inbox.ru>,
http://lists.gnu.org/archive/html/freetype-devel/2014-04/msg00001.html.
* 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>
*/*: Decorate hex constants with `U' and `L' where appropriate.
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,

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 backwards
compatilibity, 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
` ' 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.

(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):
Accept second, optional argument to specify a name.
(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>

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: Improve CSS for vertical spacing.
2014-11-29 Werner Lemberg <wl@gnu.org>
[docmaker] Improve HTML code for table of contents.
* 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 reduntant <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.

* 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.

2014-11-25 Werner Lemberg <wl@gnu.org>
[Savannah bug #43682] Add/remove `void' casts to some functions.

[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

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.

[base] CORDIC improvements.
The scaling between the hypotenuse and its CORDIC approximation is
based on regression analysis. The smaller padding for `theta' is
justifed 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.

* src/base/ftstroke.c (ft_stroker_inside): Fix border intersections.
One more place to check whether `radius' is zero.
Problem reported by Marco Wertz <marco.wertz@gmx.de>.

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.

* 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
