for cmap format 4. For overlapped but sorted segments, which is
previously considered unsorted, we still use binary search.
* src/sfnt/ttcmap.h (struct TT_CMapRec_): Replace `unsorted' by
`flags'.
(TT_CMAP_FLAG_UNSORTED, TT_CMAP_FLAG_OVERLAPPED): New macros.
* src/sfnt/ttcmap.c (OPT_CMAP4): Removed as it is always defined.
(struct TT_CMap4Rec_): Remove `old_charcode' and `table_length'.
(tt_cmap4_reset): Removed.
(tt_cmap4_init): Updated accordingly.
(tt_cmap4_next): Updated accordingly.
Take care of overlapped segments.
(tt_cmap4_validate): Make sure the subtable is large enough.
Do not check glyph_ids because some fonts set the length wrongly.
Also, when all segments have offset 0, glyph_ids is always invalid. It
does not cause any problem so far only because the check misses
equality.
Distinguish between unsorted and overlapped segments.
(tt_cmap4_char_map_linear, tt_cmap4_char_map_binary): New functions to
do "charcode => glyph index" by linear/binary search.
(tt_cmap4_char_index, tt_cmap4_char_next): Use
tt_cmap4_char_map_linear and tt_cmap4_char_map_binary.
(tt_face_build_cmaps): Treat the return value of validator as flags
for cmap.
tt_cmap12_next): New struct/function for fast "next char".
(tt_cmap12_char_map_binary): New function to do "charcode => glyph
index" by binary search.
(tt_cmap12_char_index, tt_cmap12_char_next): Use
tt_cmap12_char_map_binary.
(tt_face_build_cmaps): Check table and offset correctly (equality is
missing).
* builds/amiga/smakefile: Adjusted the compiler options
to the current sources, now really builds the gxvalid, gzip
and psnames modules.
* builds/amiga/src/base/ftsystem.c: The assumed Seek() position
in the file cache was off by one byte which could cause false
errors in font files.
before loading the table directory.
* src/sfnt/ttload.c (tt_face_load_sfnt_header,
tt_face_load_directory): Delay sfnt_dir_check from
tt_face_load_sfnt_header to tt_face_load_directory.
error code.
(sfnt_init): New function to fill in face->ttc_header. A non-TTC font
is synthesized into a TTC font with one offset table.
(tt_face_load_sfnt_header): Use sfnt_init.
Fix an invalid access when the font is TTC and face_index is -1.
of metrics instead of aborting. Patch suggested by Derek Noonburg.
* src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c
(cid_slot_load_glyph), src/type1/t1gload.c (T1_Load_Glyph): Scale
the glyph properly if no hinter is available.
* docs/CHANGES: Mention scaling bug.
patch from Mike Moening <MikeM@RetekSolutions.com>
* src/cff/cffgload.c (cff_face_get_vertical_metrics): New function.
(cff_slot_load): Use cff_face_get_vertical_metrics.
* docs/CHANGES: Updated.
invalid computations, resulting in very weird bugs in TrueType
bytecode hinted fonts
* src/truetype/ttinterp.c: redefined FT_UNUSED_EXEC to not perform
a structure copy each time. Wooot. !
Make compiling instructions in docs/CUSTOMIZE work again.
* builds/unix/unix-cc.in (CPPFLAGS): New variable.
(CFLAGS): Don't include @CPPFLAGS@.
* builds/freetype.mk (FT_CFLAGS): Add CPPFLAGS.
* src/lzw/ftlzw2.c, src/lzw/ftzopen.h, src/lzw/ftzopen.c, src/lzw/rules.mk:
first version of LZW loader re-implementation. Apparently, saves about
260 KB of heap memory when loading tir24.pcf.Z
FT_New_Size if we're opening a face with face_index < 0 (which is only
used for testing the format).
* src/gxvalid/gxvmort0.c: removed compiler warning
font to have no `head' table if tables `SING' and `META' are
present; this is to support `SING Glyphlet'.
`SING Glyphlet' is an extension to OpenType developed by Adobe
primarily to facilitate adding supplemental glyphs to an OpenType
font (with emphasis on, but not necessariy limited to, gaiji to a
CJK font). A SING Glyphlet Font is an OpenType font that contains
the outline(s), either in a `glyf' or `CFF' table, for a glyph;
`cmap', `BASE', and `GSUB' tables are present with the same format
and functionaliy as a regular OpenType font; there are no `name',
`head', `OS/2', and `post' tables; there are two new tables, `SING'
which contains details about the glyphlet, and `META' which contains
metadata.
Further information on the SING Glyphlet format can be found at:
http://www.adobe.com/products/indesign/sing_gaiji.html
* freetype2/include/freetype/ttags.h (TTAG_SING, TTAG_META): New
macros for the OpenType tables `SING' and `META'. These two tables
are used in SING Glyphlet Format fonts.
a preliminary section with some explanations about user allocation.

Don't abort if there are no data types, functions, etc., in a
section.

docs/INSTALL.GNU, docs/TRUETYPE, docs/DEBUG, docs/UPGRADE.UNX,
docs/VERSION.DLL, docs/formats.txt: Revised, formatted.
ttmetrics here. TrueType fonts with only sbits always have
ttmetrics.valid set to false.
* src/truetype/ttgload.c (TT_Load_Glyph): Check that ttmetrics is
valid before loading outline glyph.
* src/cache/ftcimage.c (FTC_INode_New): Fix a memory leak.
TT_Done_Context and rename TT_Destroy_Context to TT_Done_Context with
slight changes.

* src/truetype/ttobjs.c (tt_driver_init): Initialize execution context
here.

Return error if size is NULL.

Forget glyph frame before calling TT_Process_Simple_Glyph.

these three functions.
Set various fields of `glyph' here, instead of in load_truetype_glyph
and compute_glyph_metrics.

removing compiler warnings (Visual C++ /W4)
* Jamfile, src/otvalid/{otvcommn.h,otvgdef.c,otvgpos.c,otvgsub.c,
otvjstf.c}: modified the code to use a different pre-processor trick
to implement the OTV_NEST1, OTV_NEST2 and OTV_NEST3 macros. The code
now compiles neatly with Visual C++. The 'otvalid' module has been
put in the Jamfile build again.
ft_glyphslot_grid_fit_metrics.
* src/truetype/ttgload.c (compute_glyph_metrics): Use
ft_glyphslot_grid_fit_metrics.

ft_glyphslot_grid_fit_metrics.
FT_Outline_Get_CBox is called twice.
* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Modify metrics to more
reasonable values when emboldening outline glyphs. The theoretic
ones are unrealistic.

s/2.1.9/2.1.10/.
* docs/CHANGES, docs/VERSION.DLL: Updated.

vertBearingY to make glyphs centered vertically.
Fix some bugs in vertical metrics:
. loader->pp3.y and loader->pp4.y are in 26.6 format, not in font
units.
. As we use the glyph's cbox to calculate the top bearing now
there iss no need to adjust `top'.
