* src/base/ftobjs.c (destroy_size, destroy_face): This is such that the
generic destroy can be used to call `FT_Done_Library`. For that to work,
it needs to call it *after* having removed the face from the respective
module.
o Replace `test -e` by `test -d` (directory) and `-h`
(symlink), because pre-POSIX /bin/sh of Solaris 10
does not support `test -e`.
o Replace the combination of `head` and `sed ...` by
single sed command `sed -n 1...p`. GNU libtoolize
with Solaris 10 /bin/sh complains "Broken Pipe" for
the closure of stdout by `head`. Let `sed` receive
all stdout and discard.
Some output formats may rewrite symbol names during the output,
like the concatenation of "64__" suffix on VMS. To estimate
sufficient size to store symbol name, pass the output format
info to `names_add`. For VMS, `names_add` allocates longer
buffer to append "64__".
* apinames.c (SUFFIX_VMS_64ADDR): New macro of "64__".
(main): Pass the format info to `read_header_file`.
(read_header_file): Pass the format info to `names_add`.
(names_add): Receive the format info, and reserve the symbol
name buffer 4 byte longer in the case of VMS, to append the
suffix in `names_dump`.
* apinames.c (names_dump): For WATCOM_LBC format, the
DLL name with no suffix is constructed on a static
array temp[], but the scope is closed before use it.
The declaration of temp[] is moved to the wider
scope for the dumping part to refer it.
* src/tools/apinames.c: The first header file must be
given after the options. All arguments after the
first header file are dealt as header files to be
parsed, regardless with their leading "-".
For example,
"apinames include/freetype/freetype.h -dFREETYPE.DLL"
warns "unable to open -dFREETYPE.DLL".
Thus, the "header1" must be given after the arguments
to be parsed as the options.
* vms_name.com: Suppress a warning with the latest Clang compiler.
* builds/vms/apinames_vms.bash: Use absolute path to avoid dependency on the
environment.
* src/sfnt/ttsbit.c (tt_face_load_sbix_image): Currently undocumented by
Apple, this flips the bitmap data horizontally. It is used on macOS in
Apple Color Emoji; 19.4d6e1; 2024-02-05 (file `Apple Color Emoji.ttc`).
Fixes issue #1282.
* builds/unix/configure.raw: copy `CFLAGS` &
`LDFLAGS` values to `CFLAGS_BUILD` &
`LDFLAGS_BUILD`, in a self-hosting case.
* builds/unix/unix-cc.in: set `CCexe_CFLAGS` &
`CCexe_LDFLAGS` by `CFLAGS_BUILD` &
`LDFLAGS_BUILD`.
In some confused environments, simple building
like `cc -o apinames apinames.c` is no longer
able to build an executable running on the host.
The validity of `CC` is tested with consideration
of `CFLAGS` and `LDFLAGS`, thus, duplicating
`CFLAGS` & `LDFLAGS` to `CCexe_CFLAGS` &
`CCexe_LDFLAGS` (via XXX_BUILD) would be slightly
safer in a self-hosting build.
Fixes the issue #1296.

* include/freetype/freetype.h (FREETYPE_PATCH): Set to 3.
* builds/unix/configure.raw (version_info): Set to 26:2:20.
* CMakeLists.txt (VERSION_PATCH): Set to 3.
With ample checks against the table size, we should be able to use
macros without the limit checks and functional calls.
* src/truetype/ttgxvar.c (ft_var_readpacked{points,deltas}):
Use FT_NEXT_* instead of FT_GET_*.
The CMake build uses `find_package` to look for dependencies. Before calling `find_package` it looks to see if the dependency was disabled. If not the associated `_FOUND` variable will be set. This value is then checked to determine if the dependency is added.
However `find_package(PNG)` calls `find_package(ZLIB)` within its find module. So in the case of `FT_DISABLE_ZLIB=TRUE` and `FT_DISABLE_PNG=FALSE` the `ZLIB_FOUND` value can be set and even though `FT_DISABLE_ZLIB` is turned on.
Unset the value of `ZLIB_FOUND` after the call to `find_package(PNG)` so the value is only set when `FT_DISABLE_ZLIB` is turned off.
This change comes along with 2a7bb4596f ans is only meant to reduce
pointer casting in the code.
* include/freetype/ftimage.h (FT_Outline): Do it.
* src/*: Update `FT_Outline` users.
In C it is undefined behavior to do arithmetic on a null pointer, including
adding zero. When using NotoSansKhmer[wdth,wght].ttf UBSAN produces a report
like
ttgxvar.c:1052:31: runtime error: applying zero offset to null pointer
when adding zero to `varData->deltaSet` (which is null) to produce `bytes`.
Protect against all the potential issues of this kind by returning early if
`varData->regionIdxCount == 0`.
* src/truetype/ttgxvar.c (tt_var_get_item_delta): early return on no regions
This doubles the number or allowed points, see
https://github.com/harfbuzz/harfbuzz/issues/4752
Although it is hardly practical to use more than 32767 points,
other font engines seem to support it.
* docs/CHANGES: Announce it.
* include/freetype/ftimage.h (FT_Outline): Do it and update limits.
* src/*: Update `FT_Outline` users.
