which conditionally replaces the function with an inline version
through the macro.
2014-08-08 Alexei Podtelezhnikov <[email protected]>
* src/base/ftbitmap.c (ft_gray_for_premultiplied_srgb_bgra): Refactor.

Fix Savannah bug #42788.
* src/pfr/pfrobjs.c: Include `ftcalc.h'.
2014-07-16 Alexei Podtelezhnikov <[email protected]>
Replace `ft_highpow2' function.
* src/pfr/pfrobjs.c (pfr_face_get_kerning): Use `FT_MSB' instead of
`ft_highpow2'.
* src/base/ftutil.c, include/internal/ftobjs.h (ft_highpow2): Remove
it.
2014-07-15 Alexei Podtelezhnikov <[email protected]>

[truetype] Improve handling of buggy `prep' tables.
In case of an error in the `prep' table, no longer try to execute it
again and again. This makes FreeType handle endless loops in buggy
fonts much faster.
* src/truetype/ttobjs.h (TT_SizeRec): The fields `bytecode_ready'
and `cvt_ready' are now negative if not initialized yet, otherwise
they indicate the error code of the last run.
* src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep,
tt_size_done_bytecode, tt_size_init_bytecode,
tt_size_ready_bytecode, tt_size_init, tt_size_done, tt_size_reset):
Updated.
* src/truetype/ttgload.c (tt_loader_init): Updated.

and `prep' only if we are in the `glyf' table.
2014-07-12 Werner Lemberg <[email protected]>
* builds/vms/ftconfig.h: Synchronize.
Problem reported by Alexei.
2014-07-11 Alexei Podtelezhnikov <[email protected]>

[base] Small optimization of the ancient code.
* src/base/ftcalc.c (FT_MulDiv, FT_MulDiv_No_Round): Loosen up the
condition for direct 32-bit calculations.
2014-06-27 Werner Lemberg <[email protected]>

`unsigned' issues.
* src/autofit/aflatin.c (af_latin_metrics_init_blues): Make compiler
happy.
* src/base/ftlcdfil.c (_ft_lcd_filter_fir): Use only four elements

[autofit] Introduce neutral blue zones to the latin module.
Such blue zones match either the top or the bottom of a contour. We
need them for scripts where accent-like elements directly touch the
base character (for example, some vowel signs in Devanagari, cf.
U+0913 or U+0914).

[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.
2014-04-17 Werner Lemberg <[email protected]>
[autofit] More coverage fixes for complex scripts.
* src/autofit/hbshim.c (af_get_coverage): Merge input glyph coverage

handled properly.
Don't check blue zone characters for default coverage.
2014-04-17 Werner Lemberg <[email protected]>
Make `FT_Get_SubGlyph_Info' actually work.

2014-04-12 Werner Lemberg <[email protected]>
[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 <[email protected]>
[autofit] Improve scoring algorithm for identifying stems.
Problem reported by Karsten Lücke <[email protected]>.
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/autofit/aflatin.h: Updated.
* src/autofit/afcjk.c: Updated.

[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.
