Signedness revisions.
This eliminates explicit casting by switching to unsigned fields.

meson.build (gen_docs): Use `current_source_dir` instead of `source_root`.
These two are not equal when FreeType is used as a subproject, such as in
`freetype-demos`. In that case, `source_root` points at the root project,
causing the docs build to fail.

autogen.sh: Only copy submodules if building from a git branch.
`autogen.sh` fails if building from a standard source tarball. Firstly, git
expects to be called in a git repository, then `copy_submodule_files`
blindly attempts to copy files.
Debian, Ubuntu, Linux Mint, and other derivatives all run `autogen.sh`
before compiling to regenerate build files.
This patch ensures that various git commands are only called and 'dlg' files
are only copied if `autogen.sh` is called from a git repository.

[builds/unix] Do not use autoconf SIZEOF.
* builds/unix/ftconfig.h.in [FT_USE_AUTOCONF_SIZEOF_TYPES]: Removed.
* builds/unix/configure.raw: Remove AC_CHECK_SIZEOF and update.
After this commit, autoconf builds will fully rely on <limits.h>
rather than falling back on it if AC_CHECK_SIZEOF failed for some
reason. There is a risk that misconfigured cross-compilation might
have wrong headers. Note that Meson and CMake builds always relied on
<limits.h> for sizes and availability of integer types.

Propagate sign when reading OFF3.
Signed 24-bit values are extremely rare. FreeType only reads them in
PFR fonts with bitmap strikes conditionally. They have not been seen
in the known fonts. That is why this bug could never be discovered.
`FT_FRAME_OFF3` propagates sign correctly.
* include/freetype/internal/ftstream.h (FT_PEEK_OFF3, FT_PEEK_OFF3_LE):
Propagate sign into 32-bit value.
(FT_GET_OFF3, FT_READ_OFF3): Needed fixing but removed as unused.

`FT_Stream_Open`.
* builds/windows/ftsystem.c, builds/unix/ftsystem.c (FT_Stream_Open,

the overall performance. The loss of precision is tolerable until the
divisors (the components dx and dy) approach 32 - PIXEL_BITS. With
PIXEL_BITS = 8, this corresponds to 65,000 pixels or the bitmap size
that we refuse to render anyway.

[smooth] Detect SSE2 with MSVC for x86
MSVC does not set `__SSE2__`. Instead one must check whether `_M_IX86_FP` is
defined and greater than or equal to 2.

Use it where appropriate.

that the beginning part of a long tricky family name is already
registered as another tricky family name, no need to double-check
the longer one. Such long tricky family names are removed from

[truetype] New function to skip the randomization tag.
* src/truetype/ttobjs.c (tt_skip_pdffont_random_tag):
New function to skip the randomization tag in the names of the
fonts embedded in a PDF. It is used by tt_check_trickyness_family(),
to keep from mistaking "DLC" in the randomization tag as a
tricky font name. See discussion in:
https://lists.nongnu.org/archive/html/freetype-devel/2021-02/msg00002.html
For technical detail about the randomization tag, please find
PDF Reference 5.5.3 "Font Subsets". Thanks to Justyna Wawrzynska
for pointing out the issue caused by the randomization tag.

[sfnt] Add API for retrieving a 'COLR' v1 'ClipBox' table.

for background on the introduction of this specification change.
* include/freetype/ftcolor.h (FT_ClipBox): New structure.

with SFNT implementation.
* src/sfnt/sfdriver.c (sfnt_interface): Updated.
* src/sfnt/ttcolr.c (Colr): New field `clip_list`.
(tt_face_load_colr): Parse global clip list offset.
