tt_cmap4_char_map_binary): Handle fonts which treat the last segment
specially. According to the specification, such fonts would be
invalid but acroread accepts them.
support for bit 8 in the `OS/2' table. MS is already using this;
hopefully, this becomes part of OpenType 1.5.
Prepare also support for `name' IDs 21 (WWS_FAMILY) and 22
(WWS_SUBFAMILY).
cmap14-related new APIs to the FT_Object_ActionName scheme.
update the documentation for these APIs
* src/sfnt/ttcmap.c: stronger cmap 14 validation, make the
code a little more consistent with FreeType coding conventions
and modify the cmap14 functions that returned a newly allocated
array to use a persistent vector from the TT_CMap14 object
instead.
Fonts without a cmap must be handled correctly by FreeType (anything
else would be a bug).
* src/psaux/t1decode.c (t1_decoder_parse_charstrings)
[FT_DEBUG_LEVEL_TRACE]: Improve tracing message.
tt_sbit_decoder_load_image): Protect against integer overflows.
* src/pfr/pfrgload.c (pfr_glyph_load_simple): More bounding checks
for `x_control' and `y_control'.
new API FT_Get_Gasp to return entries of the GASP table
corresponding to a given character pixel size.
* src/sfnt/ttload.c: add version check for the GASP table,
in order to be better future-proof

appears in the documentation.
* include/freetype/ftchapters.h: Add `font_format' section.
* src/tools/docmaker/tohtml.py (HtmlFormatter::index_exit): Add link
to TOC in index page.

(platform,encoding) pair, with language_id != English
if the font uses another name entry with language_id == English,
it will be selected correctly though.
* src/truetype/ttobjs.c: add unpatent-hinting selection for
"mingli.ttf"
* freetype2/src/gxvalid/gxvmod.c (GXV_TABLE_DECL): Mark local
variable `_sfnt' as volatile since it must keep its value across
a call to ft_setjmp.
(gxv_validate): Same for local variables `memory' and `valid'.
(classic_kern_validate): Same for local variables `memory',
`ckern', and `valid'.

solved compiler warnings as well as C++ compilation problems
src/sfnt/ttsbit.h, src/sfnt/ttsbit.c: moving the definition
of 'set_sbit_strike' and 'load_sbit_metrics' to their 2.1.8
location. This is used to support binary compatibility with
the X.Org server's libXfont library.
note that this disables memory optimizations for the embedded

compiler errors/warnings when TT_CONFIG_OPTION_EMBEDDED_BITMAPS is not
defined.
* src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics): Fix
possible segment faults for the non-FT_OPTIMIZE_MEMORY'ed versions.
(finally!)
For most OpenType tables, `tt_face_load_xxxx' simply loads the table
and `face->root' is set later in `sfnt_load_face'. Here, we try to
make this work for _all_ tables.
* src/sfnt/ttsbit.c, src/sfnt/ttsbit0.c, src/sfnt/ttload.c,
src/sfnt/ttmtx.c: all `tt_face_load_xxxx' should load the table and
then exit. Error handling or setting face->root is done later in
`sfnt_load_face'.
Pretty trace messages.
* src/sfnt/sfobjs.c (sfnt_load_face): Work harder.
Mac bitmap-only fonts are not scalable.
Check that `face->header.Units_Per_EM' is not zero.
(LOAD_, LOADM_): Pretty trace messages.

fixes it.
* src/truetype/ttgload.c (load_truetype_glyph): Fix compilation error
when FT_CONFIG_OPTION_INCREMENTAL is defined.
directory (offset table and table directory) as a normal table like
the others. This also means that TTC is no longer recognized there,
but in `init_face'.
* include/freetype/internal/sfnt.h (SFNT_Interface),
src/sfnt/sfdriver.c: `load_sfnt_header' and `load_directory' are
combined and renamed to `load_font_dir'.
* src/sfnt/ttload.h, src/sfnt/ttload.c:
s/sfnt_dir_check/check_table_dir/.
`sfnt_init' is moved to sfobjs.c and renamed to `sfnt_open_font'.
`tt_face_load_sfnt_header' and `tt_face_load_directory' are combined
and renamed to `tt_face_load_font_dir'.
* src/sfnt/sfobjs.c (sfnt_init_face): Recognize TTC here.
after the tables' tags; `hdmx' is TrueType-specific and thus the code
is moved to the truetype module; `get_metrics' is moved here from the
truetype module so that the code can be shared with the cff module.
This pass involves no real changes. That is, the code is moved
verbatim mostly. The only exception is the return value of
`tt_face_get_metrics'.

src/sfnt/sfdriver.c, src/sfnt/sfnt.c, src/sfnt/sfobjs.c,
src/sfnt/ttload.c, src/sfnt/ttload.h, src/sfnt/ttsbit.c,
src/sfnt/ttsbit.h, src/sfnt/ttsbit0.c: Clean up the SFNT_Interface.
* src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: Metrics-related tables' loading
and parsing code is moved here.
Move `tt_face_get_metrics' here from the truetype module. The return
value is changed from `void' to `FT_Error'.
* include/freetype/internal/fttrace.h: New trace: ttmtx.
* src/truetype/ttpload.c, src/truetype/ttpload.h: `hdmx' loading and
parsing code is moved here.
New function `tt_face_load_prep' splitted from `tt_face_load_fpgm'.
`tt_face_load_fpgm' returns `FT_Err_Ok' if `fpgm' doesn't exist.
* src/cff/cffgload.c, src/cff/cffobjs.c: Update.
* src/truetype/ttgload.c, src/truetype/ttobjs.c: Update.
sufficient to modify a single file, `modules.cfg', to control the
inclusion of modules and base extension files.
This change also fixes the creation of ftmodule.h; it now depends on
`modules.cfg' and thus is rebuilt only if necessary.
Finally, a version of `ftoption.h' in OBJ_DIR is preferred over the
default location.
* modules.cfg: New file.
* builds/freetype.mk: Don't include `modules.mk'.
Include all `rules.mk' files as specified in `modules.cfg'.
(FTOPTION_FLAG, FTOPTION_H): New variables.

(remove_ftmodule_h): New phony target to delete `ftmodule.h'.
(distclean): Add remove_ftmodule_h.
* builds/modules.mk: (MODULE_LIST): Removed.
(make_module_list, clean_module_list): Replace targets
with...
(FTMODULE_H_INIT, FTMODULE_H_CREATE, FTMODULE_H_DONE): New
variables. Reason for the change is that it is not possible to have
a phony prerequisite which is run only if the target file must be
rebuilt (phony prerequisites act like subroutines and are *always*
executed). We only want to rebuild `ftmodule.h' if `module.cfg' is
changed.
Update all callers.
($FTMODULE_H)): Rule to create `ftmodule.h', depending on
`modules.cfg'.
* builds/toplevel.mk: Rewrite and simplify module handling.
(MODULES_CFG, FTMODULE_H): New variables.

* builds/unix/unix.mk: Include `install.mk' only if BUILD_PROJECT is
defined.
(have_mk): Don't use `strip' function.
Test for unix-def.mk in OBJ_DIR, not BUILD_DIR (and invert the test
accordingly).

* builds/os2/os2-dev.mk, builds/unix/unix-dev.mk,
builds/win32/w32-bccd.mk, builds/win32/w32-dev.mk: Don't define
BUILD_DIR but DEVEL_DIR for development header files.
* builds/ansi/ansi-def.mk (TOP_DIR, OBJ_DIR),
builds/beos/beos-def.mk (TOP_DIR, OBJ_DIR), builds/unix/unix-def.in
(TOP_DIR, OBJ_DIR): Removed. Defined elsewhere.

FT_Free_Debug) [FT_STRICT_ALIASING]: Fix typos.
* src/base/ftdbgmem.c (FT_Alloc_Debug, FT_Realloc_Debug,
FT_QAlloc_Debug, FT_QRealloc_Debug, FT_Free_Debug)
[FT_STRICT_ALIASING]: Implement.
the warp hinter isn't active (it shouldn't, still experimental)
* Jamfile, include/freetype/config/ftmodule.h: removed "gxvalid"
and "otvalid" from the list of modules that are linked statically
to a given FreeType library. Functionality has been moved to the
"ftvalid" CVS module.
note also that current Make-based build system still compiles the
modules though...
* include/freetype/config/ftoption.h: added FT_STRICT_ALIASING,
which controls the definitions of the memory management functions
to avoid warnings with recent versions of GCC. this macro is
only here to be disabled, in case we detect problems with the
new scheme.
NOTE: disable macro to use the memory debugger. this will be fixed

* include/freetype/internal/ftobjs.h (FT_Select_Metrics,
FT_Request_Metrics), src/base/ftobjs.c (FT_Select_Metrics,
FT_Request_Metrics): New base functions to set the font metrics. They
were part of FT_Select_Size/FT_Request_Size and are made independent
functions so that metrics are not set again and again.
* src/base/ftobjs.c (FT_Select_Size, FT_Request_Size): Metrics are set
only when driver's size_select/size_request is NULL. That is, drivers
should set the metrics themselves.
(FT_Match_Size): Round before matching. This was what we did and it
does cause some problems without rounding.
* src/cff/cffobjs.c (cff_size_select), src/truetype/ttdriver.c
(tt_size_select): Set the font metrics.

The scaled metrics are always preferred over strikes' metrics, even
when some strike is selected. This is done because the strikes'
metrics are not reliable, e.g., the sign of the descender is wrong for
some fonts.

FNT driver.
Introduce new size selection interface.

src/sfnt/Jamfile, src/sfnt/rules.mk, src/sfnt/sfdriver.c,
src/sfnt/ttbdf.h, src/sfnt/ttbdf.c, src/sfnt/sfobjs.c:
Added support for an embedded 'BDF ' table within SFNT-based
bitmap font files. This is used to store atoms & properties from
the original BDF fonts that were used to generate the font file.
the feature is controled by TT_CONFIG_OPTION_BDF within 'ftoption.h'
and is used to implement FT_Get_BDF_Property for these font files.
At the moment, this is still experimental, the BDF table format isn't
cast into stone yet.
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

index" by binary search.
(tt_cmap12_char_index, tt_cmap12_char_next): Use
tt_cmap12_char_map_binary.

(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.
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

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.

The next release will be 2.2.0, so don't worry about source code
backwards compatibility.
* include/freetype/ftimage.h (FT_Outline_MoveToFunc,

FT_Outline_CubicToFunc, FT_SpanFunc, FT_Raster_RenderFunc),
include/freetype/ftrender.h (FT_Glyph_TransformFunc,
FT_Renderer_RenderFunc, FT_Renderer_TransformFunc): Decorate
parameters with `const' where appropriate.
* src/sfnt/ttsbit.c (tt_face_load_sbit_image): Compute vertBearingY
to make glyphs centered vertically.
* src/truetype/ttgload.c (compute_glyph_metrics): Compute
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'.
* src/otvalid/otvcommn.h (OTV_OPTIONAL_TABLE): Use FT_UShort to be
in sync with OTV_OPTIONAL_OFFSET. Reported by YAMATO Masatake.
* docs/release: Update.
(CFLAGS), builds/compiler/gcc.mk (CFLAGS): Remove
-fno-strict-aliasing.
Say you have `(Foo*)x' and want to assign, pass, or return it as
`(Bar*)'. If you simply say `x' or `(Bar*)x', then the C compiler
would warn you that type casting incompatible pointer types breaks
strict-aliasing. The solution is to cast to `(void*)' instead which
is the generic pointer type, so the compiler knows that it should
make no strict-aliasing assumption on `x'. But the problem with
`(void*)x' is that seems like in C++, unlike C, `void*' is not a
generic pointer type and assigning `void*' to `Bar*' without a cast
causes an error. The solution is to cast to `Bar*' too, with
`(Bar*)(void*)x' as the result -- this is what the patch does.
* include/freetype/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP),
include/freetype/cache/ftcmru.h (FTC_MRULIST_LOOKUP_CMP): Remove
cast on lvalue, use a temporary pointer instead.

drastically reduce the heap usage of FreeType, especially in the case
of memory-mapped files. The idea is to avoid loading and decoding tables
in the heap, and instead access the raw data whenever possible (i.e.
when it doesn't compromise performance).
This had several impacts: first, opening vera.ttf uses a ridiculous amount
of memory (when the FT_Library footprint is accounted for), until you start
loading glyphs. Even then, you'll save at least 20 Kb compared to the non
optimized case. performance of various operations, including open/close
has also been dramatically improved.
More optimisations to come. The auto-hinter eats memory like crazy? This
must be stopped...
