* builds/unix/install-sh: Removed. It is not needed to
include repository, because autogen.sh installs it.
* builds/unix/.gitignore: Register install-sh.
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

* 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.
* builds/unix/configure.raw: New option `--disable-mmap'
is added. It is for the developers to simulate the systems
without mmap() (like 4.3BSD, minix etc) on POSIX systems.
* src/truetype/ttobjs.c (tt_check_trickyness_sfnt_ids):
Add 8 checksum sets for NEC FA family. For the tricky fonts
without some tables (e.g. NEC FA fonts lack cvt table),
extra check is added to assure that 0-length table in the
registry is not included in the font.
Some PDF generators mangle the family name badly, prioritize
the check by the sfnt table checksums than the check by the
family name. For sample PDF, see
http://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00073.html
* src/truetype/ttobjs.c (tt_check_trickyness): Exchange the order
of tt_check_trickyness_family() and tt_check_trickyness_sfnt_ids().
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.
This isn't the optimal solution yet, but it restores the previous
rendering quality (more or less).
* src/smooth/ftgrays.c (gray_render_conic): Do more splitting.
* 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++.
Patch suggested by Miles.Lau <sunliang_liu@foxitsoftware.com>.
* src/cff/cffgload.c (cff_decoder_parse_charstrings): Emit tracing
message for unknown operators and continue instead of exiting with a
syntax error.
