bcdfa386	2022-02-20T23:55:32	[cmake] Drop the support of CMake 2.x. * CMakeLists.txt: Require CMake 3.0 (released on 2014) or newer. The issue #1059 reports the difficulty to support both of CMake 2.x and newer one by single CMakeLists.txt without the inflation of cmake_policy() workarounds. For better maintainability, the support of CMake 2.x is dropped.
6c5522c6	2022-02-19T13:37:07	* src/bdf/README: Updated.
ca46bc0c	2022-02-19T13:34:05	* builds/mac/ftmac.c, src/base/ftmac.c: s\|FT_MAC_H\|<freetype/ftmac.h>\|.
5b26e92a	2022-02-19T05:26:53	src/sfnt/ttkern.c (tt_face_load_kern): Micro-optimize. A kerning table can be handled by binary search if it has equal entries. Fixes #1132.
20ec99be	2022-02-17T13:35:52	[builds/windows] Add support for legacy UWP builds. * builds/windows/ftsystem.c: Add neccessary macro substitutions to enable strict UWP builds. See !141. Co-authored-by: Alexei Podtelezhnikov <apodtele@gmail.com>
01d4deb0	2022-02-16T14:21:00	ftmm.h: Minor documentation improvement.
00ae29fc	2022-02-12T23:42:08	[pshinter] Tune PSH_STRONG_THRESHOLD_MAXIMUM value. Before the change, the hinting engine frequently confused horizontal stem and serif hints making some stems too thin and some serifs too thick. The value was tuned using serif fonts from the URW+ base 35 collection. * src/pshinter/pshalgo.c [PSH_STRONG_THRESHOLD_MAXIMUM]: s/30/12/.
5a53e51b	2022-02-12T07:58:43	t1tables.h: Documentation improvements.
c67ecb8c	2022-02-12T07:52:57	t1tables.h: Whitespace.
338b4e88	2022-02-11T19:32:49	[type42] Fix `FT_Get_PS_Font_Private` for this format. Since Type42 fonts don't have a 'Private' dictionary, the return value should be `FT_Err_Invalid_Argument`. * src/type42/t42drivr.c (t42_ps_get_font_private): Removed. (t42_service_ps_info): Updated.
1680885a	2022-02-09T16:41:07	[pshinter] Clear reused mask. In PS hinter, memory allocations persist until the module is done. Therefore, we have to clear reused masks. * src/pshinter/pshrec.c (ps_mask_table_alloc): Clear reused mask.
0447df71	2022-02-09T15:04:58	[pshinter] Use unsigned indices. This reduces casting and eliminates some checks. * src/pshinter/pshrec.c (ps_mask_test_bit, ps_mask_table_merge, ps_dimension_add_t1stem, ps_hints_t1stem3): Updated. (ps_dimension_add_counter): Updated, unnecessary checks removed.
ed0e2e76	2022-02-08T16:35:14	[pshinter] Fix mask merging. We forgot to update the number of bits when merging a larger mask into a smaller one. This fix might have rendering effects. * src/pshinter/pshrec.c (ps_mask_table_merge): Inherit the number of bits from a larger mask. There is no need to zero unused bits, already zeroed during allocation. (ps_mask_clear_bit): Removed. (ps_mask_ensure): Minor.
7c6b2f20	2022-02-08T14:37:34	[pshinter] Revise the hint table handling. * src/pshinter/pshrec.c (ps_hint_table_ensure): Remove redundant size check; avoid array zeroing because it is fully initialized when used. (ps_hint_table_alloc): Fix off-by-one comparison and remove another zeroing of the array elements.
24db55ec	2022-02-05T09:06:39	Various minor doc fixes.

8e39e42e	2022-02-02T11:35:14	[psaux] Revise `PS_Table` handling. The old impleemntation was not using `FT_REALLOC`, buing too careful with the offset rebasing. It shoudl be safe to rely on the base movements. * src/psaux/psobjs.c (reallocate_t1_table, shift_elements): Combine into... (ps_table_realloc): ... this function based on `FT_REALLOC`. (ps_table_done): Simplified. (ps_table_add): Updated.

7fd03a3e	2022-01-30T20:50:42	* CMakeLists.txt: Include 'FindPkgConfig' module. Older cmake versions don't provide `pkg_check_modules` by default. Fixes #1126.
da877c86	2022-01-29T22:46:56	* src/psaux/psobjs.c (ps_parser_load_field): Reduce `string` scope.
35740aa6	2022-01-28T12:04:36	[cmake] Check the availability of `bzip2.pc'. (CMakeLists.txt): Check the availability of `bzip2.pc'. * If `bzip2.pc' is available, Requires.private should include bzip2, but Libs.private should not include -lbz2. * If `bzip2.pc' is unavailable, Requires.private cannot include bzip2, but Libs.private should include -lbz2. Fix #897.
fa226478	2022-01-28T15:20:12	* unix/configure.raw: We need 'librsvg' version 2.46.0 or newer. Older versions don't have function `rsvg_handle_get_intrinsic_dimensions`.
b34741c1	2022-01-27T22:55:34	Minor clean-ups. * src/base/ftrfork.c (raccess_make_file_name): Do not set error. * src/sfnt/sfdriver.c (get_win_string, get_apple_string): Ditto. * src/cff/cffobjs.c (cff_strcpy): Do not confuse about error. * src/psaux/psobjs.c (ps_table_done): Ditto. * src/truetype/ttgxvar.c (ft_var_readpacked*, ft_var_load_avar): Ditto.
e34a860a	2022-01-27T11:50:12	Document `FT_Outline_Decompose` degenerate segments. `FT_Outline_Decompose` does not filter out and can return degenerate segments in an outline. This can be surprising when attemping to stroke such an outline. Clarify the existing documentation on this matter to cover all forms of degeneracy (without specifying exactly how they will be reported), why they might arise, and better explain in what cases they may be an issue. * include/freetype/ftoutlin.h (FT_Outline_Decompose): update documentation. Fixes #952.
ab1c98ac	2022-01-27T15:23:47	Fix sdf computation while `USE_SQUARED_DISTANCES`. Function `map_fixed_to_sdf` expects spread to be absolute and not squared. * src/sdf/ftbsdf.c (finalize_sdf): Pass absolute spread while `map_fixed_to_sdf`. * src/sdf/ftsdf.c (sdf_generate_bounding_box): Ditto.

8b7226bb	2022-01-25T14:28:45	* builds/unix/configure.raw (FT_DEMO_CFLAGS): Pass `-DHAVE-LIBRSVG`. This helps in decoupling library support from `pkg-config` for other platforms.
6a8e95b7	2022-01-25T08:49:41	Update documentation for `FT_LOAD_COLOR`.
5e9caaee	2022-01-24T12:19:20	[pshinter] Ensure all point flags are initialized. Only off curve point flags were fully initialized. * src/pshinter/pshalgo.c (psh_glyph_init): always initialize flags. Fixes: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=43930
65774521	2022-01-24T07:57:20	.mailmap: Typo.

112527dd	2022-01-22T11:45:30	[sfnt] Reject malformed SVG tables. * src/sfnt/ttsvg.c (SVG_TABLE_HEADER_SIZE, SVG_DOCUMENT_RECORD_SIZE, SVG_DOCUMENT_LIST_MINIMUM_SIZE, SVG_MINIMUM_SIZE): New macros. (tt_face_load_svg): Check offsets. Check table and record sizes. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=43918
706c79a1	2022-01-21T22:46:35	* src/psaux/psobjs.c (ps_table_new): Revert to zeroing.

06c1a25e	2021-12-25T17:59:42	Add flag `FT_CONFIG_OPTION_SVG`. This flag is going to be used to conditionally compile support for OT-SVG glyphs. FreeType will do the parsing and rely on external hooks for rendering of OT-SVG glyphs. * devel/ftoption.h, include/freetype/config/ftoption.h (FT_CONFIG_OPTION_SVG): New flag.
0b635b1e	2022-01-20T15:06:25	[pshinter] Avoid unnecessary zeroing. * src/pshinter/pshalgo.c (psh_hint_table_init,psh_glyph_init, psh_glyph_interpolate_normal_points): Use FT_QNEW_ARRAY.
99a940f8	2022-01-20T15:06:09	* include/freetype/freetype.h: Clarify `FT_Size` life cycle.
054782c4	2022-01-19T22:14:06	[base] Undefined scale means no scale. It might be surprising that FreeType does not have default ppem and the size has to be set explicitly or face undefined behavior with undefined variables and errors. This offers an alternative to missing or zero scale by simply setting FT_LOAD_NO_SCALE. Defined behavior is bettr than undefined one. This is alternative to !132 and discussed in https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=43708 * src/base/ftobjs.c (FT_Load_Glyph): Deal with zero scale. * include/freetype/freetype.h: Document it.
773e31c7	2022-01-18T14:05:46	* src/autofit/afglobal.c (af_face_globals_new): Reduce zeroing. Everything in AF_FaceGlobals is initialized except metrics. Those are zeroed here and initialized on demand later.
d118bf8e	2022-01-15T23:09:53	[bdf,type1] Avoid unnecessary hash zeroing. * src/bdf/bdflib.c (_bdf_parse_start): Use `FT_QALLOC`. * src/type1/t1load.c (parse_subrs): Use `FT_QNEW`.
3f6497bd	2022-01-15T22:44:28	Add Watcom C/C++ calling. In the unlikely case the source is built with OpenWatcom's -ec? switches to enforce a calling convention, the qsort() compare function must still be set to __watcall. * include/freetype/internal/compiler-macros.h (FT_COMPARE_DEF): Updated.
5e227133	2022-01-15T17:08:18	[pshinter] Avoid accessing uninitialized zone. The `normal_top.count` may be 0, implying no `normal_top.zones` exist. The code must not access these (non-existent) `normal_top.zones`. * src/pshinter/pshalgo.c (ps_hints_apply): Do not assume that `normal_top.zones[0]` is initialized. Test `normal_top.count` before using `normal_top.zones[0]`. Do not rescale if there are no `zones`. Fixes: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=43675
edd4fedc	2022-01-14T22:53:57	[cache] Avoid unnecessary zeroing. * src/cache/ftccmap.c (ftc_cmap_node_new): Use `FT_QNEW`. * src/cache/ftcimage.c (FTC_INode_New): Ditto. * src/cache/ftcsbits.c (FTC_SNode_New): Ditto.

ba5d661f	2022-01-14T21:54:17	* src/sdf/ftbsdf.c (ED): s/near/prox/. This works around the Watcom C definition of `near` as restricted __near.
7f7bf6f0	2022-01-14T20:33:28	* include/freetype/internal/compiler-macros.h [FT_COMPARE_DEF]: Tighten. This works around Watcom C library using __watcall.
7eb9a9db	2022-01-14T14:40:11	* src/pshinter/pshglob.c (psh_globals_new): Avoid zeroing. This large allocation is followed by careful initialization. Whatever is missed should be initialized manually.
81b81feb	2022-01-14T18:22:23	* src/base/fthash.c (hash_insert): Avoid unnecessary zeroing.
904ad212	2022-01-13T23:38:56	* src/bdf/bdflib.c (_bdf_parse_glyphs): Remove redundant assignment.
ee52b571	2022-01-13T09:45:48	* src/lzw/ftlzw.c (FT_Stream_OpenLZW): Avoid unnecessary zeroing.
6ee89519	2022-01-12T15:12:53	[bzip2] Reset bzip stream on any error. According to the bzip documentation it is undefined what will happen if `BZ2_bzDecompress` is called on a `bz_stream` it has previously returned an error against. If `BZ2_bzDecompress` returns anything other than `BZ_OK` the only valid next action is `BZ2_bzDecompressEnd`. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=43564 * src/bzip2/ftbzip2.c (FT_BZip2FileRec_): Add `reset` to track the need to reset the stream. (ft_bzip2_file_init): Initialize `reset` to 0. (ft_bzip2_file_reset): Set `reset` to 0 after resetting. (ft_bzip2_file_fill_output): Set `reset` to 1 when `BZ2_bzDecompress` returns anything other than `BZ_OK`.
b647dbde	2022-01-12T06:21:52	.gitlab-ci.yml: Minor comment cleanups.
ca44a236	2022-01-12T04:26:39	.gitlab-ci.yml: Add steps to `before_script` to ensure recent CA. Fetch current list of valid CAs from Windows Update and manually import them to trusted datastore. This action is required to make downloads work from sites that need recent Let's Encrypt ISRG Root X1 certificate.
f1d3b9f1	2022-01-11T17:15:35	Revert "[bzip2] Avoid use of uninitialized memory." This reverts commit d276bcb7f0c02c20d3585b2e5626702df6d140a6. The original commit did avoid the use of uninitialized memory. However, it appears that the original commit is no longer required. The underlying issue was resolved by a change in freetype2-testing "Build bzip2 correctly." [0]. Prior to [0] bzip2 was built without msan, so bzip2 writes were not tracked or considered initialized. Clearing `buffer` in the original commit allowed msan to see the `buffer` content initialized once in FreeType code, but msan saw no writes into buffer from bzip2. With bzip2 now built with msan, the bzip2 writes are properly instrumented and msan sees the bzip2 writes into the buffer. As a result the original commit can be safely reverted to allow for better detection of other uninitialized data scenarios. * src/bzip2/ftbzip2.c (FT_Stream_OpenBzip2): Revert to using `FT_QNEW`. [0] https://github.com/freetype/freetype2-testing/commit/3c052a837a3c960709227a0d6ddd256e87b88853
e838c37c	2022-01-11T11:14:32	[type42] Track how much type42 ttf data is available. Currently `T42_Open_Face` eagerly allocates 12 bytes for the ttf header data which it expects `t42_parse_sfnts` to fill out from /sfnts data. However, there is no guarantee that `t42_parse_sfnts` will actually be called while parsing the type42 data as the /sfnts array may be missing or very short. This is also confusing behavior as it means `T42_Open_Face` is tightly coupled to the implementation of the very distant `t42_parse_sfnts` code which requires at least 12 bytes to already be reserved in `face->ttf_data`. `t42_parse_sfnts` itself eagerly updates `face->ttf_size` to track how much space is reserved for ttf data instead of traking how much data has actually been written into `face->ttf_data`. It will also act strangely in the presense of multiple /sfnts arrays. * src/type42/t42objs.c (T42_Open_Face): ensure `ttf_data` is initialized to NULL. Free `ttf_data` on error. * src/type42/t42parse.c (t42_parse_sfnts): delay setting `ttf_size` and set it to the actual number of bytes read. Ensure `ttf_data` is freed if there are multiple /sfnts arrays or there are any errors.

While using zlib in 'solo' mode (via the `Z_SOLO` macro), we actually include some standard header files, making the typedef fail on systems where the native `ptrdiff_t` type differs. Fixes #1124. * src/zlib/zutil.h: Comment out definition; it doesn't work on Windows. * src/zlib/patches/freetype-zlib.diff: Updated.
da8a8b8b	2022-01-10T17:25:47	[zlib] Some organizational changes. We now first apply zlib's `zlib2ansi` script, then FreeType's patch file. * src/gzip/README.freetype: Updated. * patches/0001-zlib-Fix-zlib-sources-to-compile-for-FreeType.patch: Renamed to... * patches/freetype-zlib.diff: This. Clean up description, then regenerate it as follows: - Copy unmodified files from `zlib` repository. - Run `zlib2ansi` script. - Run `git diff -R > patches/freetype-zlib.diff.new`. - Insert patch description of old diff file, then replace old diff with new diff file.
a25e85ed	2021-08-17T15:20:25	[gzip] Update sources to zlib 1.2.11 This can be tested by building with the Unix development build make setup devel make or by building the freetype-demos programs with meson setup build -Dfreetype2:zlib=internal meson compile -C out and trying to run `ftview` with a `.pcf.gz` font file. * src/gzip/ftgzip.c, src/gzip/rules.mk: Update for new zlib sources. Also remove the temporary fix introduced in commit 6a431038 to work around the fact that the internal sources were too old. * src/gzip/README.freetype: New file describing the origin of the sources and how they were modified. * src/gzip/patches/: Patch files applied to original sources. src/gzip/*: Updated zlib sources with the patch file(s) from `src/gzip/patches/` applied, followed by a conversion with zlib's `zlib2ansi` script.
0d343863	2021-08-17T17:27:36	[meson] Change Zlib configuration option. * meson_options.txt, meson.build: Change the format of the 'zlib' meson build configuration option to be a combo with the following choices: - none: Do not support gzip-compressed streams at all. - internal: Support gzip-compressed streams using the copy of the gzip sources under `src/gzip/`; this should only be used during development to ensure these work properly. - external: Support gzip-compressed streams using the 'zlib' Meson subproject, linked as a static library. - system: Support gzip-compressed streams using a system-installed version of zlib. - auto: Support gzip-compressed streams using a system-installed version of zlib, if available, or using the 'zlib' subproject otherwise. This is the default. - disabled: Backward-compatible alias for 'none'. - enabled: Backward-compatible alias for 'auto'.
d276bcb7	2022-01-09T07:48:59	[bzip2] Avoid use of uninitialized memory. * src/bzip2/ftbzip2.c (FT_Stream_OpenBzip2): Don't use `FT_QNEW` but `FT_NEW` for setting up `zip` to avoid uninitialized memory access while handling malformed PCF fonts later on. Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=42800
ca011128	2022-01-08T22:28:44	[sfnt] Fix off-by-one error. The 0-base index is equal to the number of previosly parsed entries. It is an error to adjust it by one to get the number truncated by a stream error. This is probably inconsequential because valid entries are correctly accounted for. * src/sfnt/ttload.c (check_table_dir): Do not adjust the truncated number of tables.
7a493e3a	2022-01-08T10:28:19	[sfnt, type42] Correct previous commit. Really fix https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=42773. * src/sfnt/ttload.c (check_table_dir): Revert change. * src/type42/t42.parse.c (t42_parse_sfnts): Don't use `FT_QREALLOC` but `FT_REALLOC` for setting up `ttf_data` to avoid uninitialized memory access while handling malformed TrueType fonts later on.
bf9b1ef9	2022-01-07T10:25:52	* src/sfnt/ttload.c (check_table_dir): Initialize `table`. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=42773
b5c2172f	2022-01-07T06:53:44	[sfnt] Avoid 'runtime error: applying zero offset to null pointer'. * src/sfnt/ttsbit.c (tt_sbit_decoder_load_byte_aligned): Exit early if `line` is NULL.
5aa2a5c3	2022-01-07T06:41:36	[autofit, pshinter] Use `FT_OFFSET`. This avoids ``` runtime error: applying zero offset to null pointer ``` warnings of clang's undefined behaviour sanitizer. * src/autofit/afcjk.c (af_cjk_hints_link_segments, af_cjk_hints_compute_edges, af_cjk_hints_compute_blue_edges, af_cjk_hint_edges, af_cjk_align_edge_points): Do it. * src/autofit/afhints.c (af_glyph_hints_align_edge_points, af_glyph_hints_align_strong_points): Ditto. * src/autofit/aflatin.c (af_latin_metrics_init_widths, af_latin_hints_link_segments, af_latin_hints_compute_edges, af_latin_hints_compute_blue_edges, af_latin_hint_edges): Ditto. * src/pshinter/pshalgo.c (psh_hint_table_init): Ditto.
afb4ca01	2022-01-06T12:54:15	[truetype] Reset localpoints when varying cvt. When iterating over the cvt tuples and reading in the points it is necessary to set all of `localpoints`, `points`, and `point_count` in all cases. The existing code did not reset `localpoints` to `NULL` when there were no private point numbers. If the previous tuple did have private point numbers and set `localpoints` to `ALL_POINTS` this would not be cleared and the wrong branch would be taken later, leading to possible heap buffer overflow. * src/truetype/ttgxvar.c (tt_face_vary_cvt): Reset `localpoints` to `NULL` when it isn't valid. Fixes: https://crbug.com/1284742
2b672e72	2022-01-02T18:33:03	* builds/unix/configure.raw: Restore `SYSTEM_ZLIB` variable. This was accidentally removed with commit 93ebcbd0 almost eight years ago.
4eb6cb88	2021-12-25T09:23:58	Fix warnings for CMake Unity builds. * src/cache/ftcbasic.c (FT_COMPONENT): Undefine macro before redefinition. * src/smooth/ftgrays.c (TRUNC, FRACT): Ditto.
4f357118	2021-12-17T11:22:09	Clang-Tidy warning fixes. * src/base/ftobjs.c (FT_Get_Paint): Operator has equivalent nested operands. * src/bdf/bdflib.c (_bdf_add_property): Value stored to `fp` is never read. * src/sdf/ftbsdf.c (bsdf_init_distance_map): Value stored to `pixel` is never read. * src/sdf/ftsdf.c (split_sdf_shape): Value stored to `error` is never read.
d6a5c577	2021-12-13T23:40:16	* meson.build: Optimize lookup for `python3` program. The python module's `find_installation` method is intended to provide routines for compiling and installing python modules into the `site-packages` directory. It does a couple of slow things, including run an introspection command to scrape sysconfig info from the detected interpreter, which are not needed for the sole use case of invoking the found installation as an executable. Furthermore, when invoked without the name or path of a python binary, it is hardcoded to always look for `python3` corresponding to the interpreter meson itself uses to run. So using `find_installation` did not even allow detecting `python2` as a fallback. Instead, switch to a simple `find_program` lookup that finishes as soon as the program is found.
57fd6180	2021-12-13T23:33:03	* builds/meson/*.py: Fix name of python executable for auxiliary scripts. The previous change to check the return code of `run_command` invocations caused the CI to fail. Although most scripts used `python_exe` as the program command, the script to determine the project version did not. But, all scripts used `python` as the shebang, and this is not available on all systems. Particularly Debian does not provide a `python` command, though `python3` does exist. This meant that formerly the version number was lacking, and now the build simply fails. Instead, rely on `python3` since it is guaranteed to exist when running meson, and `python2` is end of life anyway.
e342f83c	2021-12-13T22:50:18	* meson.build: Check the return value of `run_command`. By default, errors are not checked and a command that is somehow broken will just capture incorrect output (likely an empty string). Current development versions of meson now raise a warning for this implicit behavior, and advise explicitly setting the `check:` keyword argumend to determine whether a failing return code should be considered an error. Since none of the commands in this project are expected to fail, mark them as required to succeed.

Revert "[bzip2] Avoid use of uninitialized memory." This reverts commit d276bcb7f0c02c20d3585b2e5626702df6d140a6. The original commit did avoid the use of uninitialized memory. However, it appears that the original commit is no longer required. The underlying issue was resolved by a change in freetype2-testing "Build bzip2 correctly." [0]. Prior to [0] bzip2 was built without msan, so bzip2 writes were not tracked or considered initialized. Clearing `buffer` in the original commit allowed msan to see the `buffer` content initialized once in FreeType code, but msan saw no writes into buffer from bzip2. With bzip2 now built with msan, the bzip2 writes are properly instrumented and msan sees the bzip2 writes into the buffer. As a result the original commit can be safely reverted to allow for better detection of other uninitialized data scenarios. * src/bzip2/ftbzip2.c (FT_Stream_OpenBzip2): Revert to using `FT_QNEW`.

[type42] Track how much type42 ttf data is available. Currently `T42_Open_Face` eagerly allocates 12 bytes for the ttf header data which it expects `t42_parse_sfnts` to fill out from /sfnts data. However, there is no guarantee that `t42_parse_sfnts` will actually be called while parsing the type42 data as the /sfnts array may be missing or very short. This is also confusing behavior as it means `T42_Open_Face` is tightly coupled to the implementation of the very distant `t42_parse_sfnts` code which requires at least 12 bytes to already be reserved in `face->ttf_data`. `t42_parse_sfnts` itself eagerly updates `face->ttf_size` to track how much space is reserved for ttf data instead of traking how much data has actually been written into `face->ttf_data`. It will also act strangely in the presense of multiple /sfnts arrays. * src/type42/t42objs.c (T42_Open_Face): ensure `ttf_data` is initialized to NULL. Free `ttf_data` on error. * src/type42/t42parse.c (t42_parse_sfnts): delay setting `ttf_size` and set it to the actual number of bytes read. Ensure `ttf_data` is freed if there are multiple /sfnts arrays or there are any errors.

[truetype] Reset localpoints when varying cvt. When iterating over the cvt tuples and reading in the points it is necessary to set all of `localpoints`, `points`, and `point_count` in all cases. The existing code did not reset `localpoints` to `NULL` when there were no private point numbers. If the previous tuple did have private point numbers and set `localpoints` to `ALL_POINTS` this would not be cleared and the wrong branch would be taken later, leading to possible heap buffer overflow. * src/truetype/ttgxvar.c (tt_face_vary_cvt): Reset `localpoints` to `NULL` when it isn't valid.

* meson.build: Optimize lookup for `python3` program. The python module's `find_installation` method is intended to provide routines for compiling and installing python modules into the `site-packages` directory. It does a couple of slow things, including run an introspection command to scrape sysconfig info from the detected interpreter, which are not needed for the sole use case of invoking the found installation as an executable. Furthermore, when invoked without the name or path of a python binary, it is hardcoded to always look for `python3` corresponding to the interpreter meson itself uses to run. So using `find_installation` did not even allow detecting `python2` as a fallback. Instead, switch to a simple `find_program` lookup that finishes as soon as the program is found.

* builds/meson/*.py: Fix name of python executable for auxiliary scripts. The previous change to check the return code of `run_command` invocations caused the CI to fail. Although most scripts used `python_exe` as the program command, the script to determine the project version did not. But, all scripts used `python` as the shebang, and this is not available on all systems. Particularly Debian does not provide a `python` command, though `python3` does exist. This meant that formerly the version number was lacking, and now the build simply fails. Instead, rely on `python3` since it is guaranteed to exist when running meson, and `python2` is end of life anyway.

* meson.build: Check the return value of `run_command`. By default, errors are not checked and a command that is somehow broken will just capture incorrect output (likely an empty string). Current development versions of meson now raise a warning for this implicit behavior, and advise explicitly setting the `check:` keyword argumend to determine whether a failing return code should be considered an error. Since none of the commands in this project are expected to fail, mark them as required to succeed.
