To remove extremas of vertical strokes of CJK Ideographs at
low resolution and make the top and bottom horizontal stems
aligned, bluezones for CJK Ideographs are calculated from
sample glyphs. At present, vertical bluezones (bluezones
to align vertical stems) are disabled by default. For detail, see
http://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00070.htmlhttp://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00092.htmlhttp://lists.gnu.org/archive/html/freetype-devel/2011-05/msg00001.html
* include/freetype/internal/fttrace.h: New trace component `afcjk'.
* src/autofit/afcjk.h (AF_CJK{Blue,Axis,Metric}Rec): Add CJK version
for AF_Latin{Blue,Axis,Metric}Rec.
(af_cjk_metrics_check_digits): Ditto, shared with Indic module.
(af_cjk_metrics_init_widths): Ditto.
(af_cjk_metrics_init): Take AF_CJKMetric instead of AF_LatinMetric.
(af_cjk_metrics_scale): Ditto (declaration).
(af_cjk_hints_init): Ditto (declaration).
(af_cjk_hints_apply): Ditto (declaration).
* src/autofit/afcjk.c (af_cjk_metrics_scale): Ditto (body).
(af_cjk_hints_init): Ditto (body).
(af_cjk_hints_apply): Ditto (body).
(af_cjk_metrics_init_widths): Duplicate af_latin_metrics_init_widths.
(af_cjk_metrics_check_digits): Duplicate af_latin_metrics_check_digits.
(af_cjk_metrics_init): Call CJK bluezone initializer.
(af_cjk_metrics_scale_dim): Add code to scale bluezones.
(af_cjk_hints_compute_blue_edges): New function, CJK version of
af_latin_hints_compute_blue_edges.
(af_cjk_metrics_init_blues): New function, CJK version of
af_latin_metrics_init_blues.
(af_cjk_hints_edges): Add code to align the edge stems to blue zones.
* src/autofit/afindic.c (af_indic_metrics_init): Take AF_CJKMetric
instead of AF_LatinMetric, and initialize as af_cjk_metrics_init.
However bluezones are not initialized.
(af_indic_metrics_scale): Take AF_CJKMetric instead of AF_LatinMetric.
(af_indic_hints_init): Ditto.
(af_indic_hints_apply): Ditto.
* docs/CHANGES: Note about CJK bluezone support.
This makes FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH redundant,
deprecated, and ignored. The new behavior is what every major user
of FreeType has been requesting. Global advance is broken in many
CJK fonts. Just ignoring it by default makes most sense.
* src/truetype/ttdriver.c (tt_get_advances),
src/truetype/ttgload.c (TT_Get_HMetrics, TT_Get_VMetrics,
tt_get_metrics, compute_glyph_metrics, TT_Load_Glyph),
src/truetype/ttgload.h: Implement it.
* docs/CHANGES: Updated.
Previously, signed integers were converted to unsigned integers, but
this can fail because of sign extension. For example, 0xa344a1eb
becomes 0xffffffffa344a1eb.
We now do the reverse which is always correct because the integer
size is the same during the cast from unsigned to signed.
* include/freetype/internal/ftstream.h, src/base/ftstream.c
(FT_Stream_Get*): Replace with...
(FT_Stream_GetU*): Functions which read unsigned integers.
Update all macros accordingly.
* src/gzip/ftgzip.c (ft_gzip_get_uncompressed_size): Updated.
* include/freetype/config/ftconfig.h: Ported the FT_MulFix_i386
function from GNU inline assembly syntax (see #ifdef __GNUC__ block
above) to MASM syntax for Microsoft Visual C++.
* include/freetype/config/ftconfig.h (FT_MulFix_arm):
Copy the maintained code from builds/unix/ftconfig.in.
Old GNU binutils could not accept the reduced syntax
`orr %0, %2, lsl #16'. Un-omitted syntax like RVCT,
`orr %0, %0, %2, lsl #16' is better. Reported by
Johnson Y. Yan. The bug report by Qt developers is
considered too.

Too serious check of errors by `FT_CMap_New' since 2010-07-04
is fixed. Reported by Tor Andersson.

(PSnames_Err_No_Unicode_Glyph_Name): New error code to
indicate the Unicode charmap synthesis failed because
no Unicode glyph name is found.
* src/psnames/psmodule.c (ps_unicodes_init): Return
PSnames_Err_No_Unicode_Glyph_Name when no Unicode glyph name
is found in the font.
* src/cff/cffcmap.c (cff_cmap_unicode_init): Return
CFF_Err_No_Unicode_Glyph_Name when no SID is available.
* src/type1/t1objs.c (T1_Face_Init): Proceed if `FT_CMap_New'
is failed by the lack of Unicode glyph name.

minimum character code passed by a legacy rogue client by...
* include/freetype/config/ftoption.h (FT_MAX_CHARMAP_CACHEABLE):
This. It is undefined when FT_CONFIG_OPTION_OLD_INTERNALS is
undefined (thus the rogue client compatibility is not required).
* src/cff/cffobjs.c (cff_face_init): Abort the automatic
selection or synthesis of Unicode cmap subtable when the charmap
index exceeds FT_MAX_CHARMAP_CACHEABLE.
* src/sfnt/ttcmap.c (tt_face_build_cmaps): Issue error message
when the charmap index exceeds FT_MAX_CHARMAP_CACHEABLE.
* src/base/ftobjs.c (find_unicode_charmap): When Unicode charmap
is found after FT_MAX_CHARMAP_CACHEABLE, ignore it and search
earlier one.
(find_variant_selector_charmap): When UVS charmap is found after
FT_MAX_CHARMAP_CACHEABLE, ignore it and search earlier one.
(FT_Select_Charmap): When a charmap matching with requested
encoding but after FT_MAX_CHARMAP_CACHEABLE, ignore and search
earlier one.
(FT_Set_Charmap): When a charmap matching with requested
charmap but after FT_MAX_CHARMAP_CACHEABLE, ignore and search
earlier one.
(FT_Get_Charmap_Index): When a requested charmap is found
after FT_MAX_CHARMAP_CACHEABLE, return the inverted charmap
index.
* src/base/ftstream.c (FT_Stream_EnterFrame): Exit with error
if the frame size is larger than the stream size.
* src/base/ftsystem.c (ft_ansi_stream_io): Exit with error if
seeking a position larger than the stream size.
* include/freetype/fterrdef.h
(BDF_Err_Missing_Fontboundingbox_Field): New error code.
* src/bdf/bdflib.c (_bdf_parse_start): Check for missing
`FONTBOUNDINGBOX' field.
Avoid memory leak if there are multiple `FONT' lines (which is
invalid but doesn't hurt).
This is based on code written by Lifter
<http://unixforum.org/index.php?showuser=11691>. It fixes

After long discussion, we now consider the character width vector
(wx,wy) returned by the `sbw' Type 1 operator as being part of *one*
direction only. For example, if you are using the horizontal
writing direction, you get the horizontal and vertical components of
the advance width for this direction. Note that OpenType and CFF fonts
don't have such a vertical component; instead, the GPOS table can be
used to generate two-dimensional advance widths (but this isn't
handled by FreeType).
* include/freetype/ftincrem.h (FT_Incremental_MetricsRec): Add
`advance_v' field to hold the vertical component of the advance
value.
* src/truetype/ttgload.c (tt_get_metrics), src/cff/cffgload.c
(cff_slot_load), src/type1/t1gload.c
(T1_Parse_Glyph_And_Get_Char_String), src/cid/cidgload.c
(cid_load_glyph): Use it.
