[sfnt] Update paint format values to support non-variable paints.
* freetype.h (FT_PaintFormat): Update paint format identifiers after
a specification change. The specification was updated to have
sibling formats, variable and non-variable variants for each.
Reflect that here.
* sfnt/ttcolr.c (read_paint): Remove parsing of variable indices as
the non-variable formats no longer have them.

* CMakeLists.txt: Improve 'bz2' support.
Not all distributions such as FreeBSD provide a `.pc` file for
'(lib)bz2' so follow autotools and add it to `Libs.private` instead.

* meson.build: s/freetype2_dep/freetype_dep/.
Many projects (e.g., fontconfig, cairo) hardcode the `freetype_dep`
variable name to use FreeType as subproject because that was the
variable name in Centricular's Meson port of FreeType. While they
should stop hardcoding that variable name, it does not cost us
anything to keep using that name to ease transition.

[meson] Fix handling of HarfBuzz library.
* meson.build (harfbuzz_dep): Do not fall back to HarfBuzz by
default.
Otherwise it causes a dependency cycle:
cairo => fontconfig => freetype2 => harfbuzz => cairo
Meson will still fall back to HarfBuzz subprojects if the `harfbuzz`
option is set to `enabled` instead of `auto` and a
`subprojects/harfbuzz.wrap` file is present. In that case it is the
responsibility of the main project to set the proper options on each
subproject to break the dependency cycle.
Fixes: #1028.

Meson: Fix dependency lookup and generate ftconfig.h
[meson] Fix dependency lookup and generate `ftconfig.h`.
- zlib: If not found on the system, meson can build it as a
subproject. We thus never use the (outdated) zlib support that
comes with FreeType. Doing so has the additional advantage that
the zlib code can be shared with other projects like GLib if both
are subprojects of an application.
- harfbuzz: Build as a subproject if not found on the system.
- 'QUESTION: What if the compiler doesn't support `-D` but uses `/D`
instead as on Windows?' Answer: Meson translate arguments for us.
- visibility: Replace self-made code with meson-specific solution.
* meson.build (ft2_defines): Rewrite logic to set and handle it.
(process_header_command): New variable, previously called
`ftoption_command`.
(ftoption_command, ftconfig_command): New variables.
(zlib_option): Removed.

* meson.build: s/ft2_libtool_version/ft2_pkgconfig_version/.

`ft2_libtool_version` would be the shared library version, not the
one we should use in file `freetype2.pc`.

|

|
2020-10-26T11:31:19
|
|
* meson.build: Use `meson.override_dependency`.
This is a new meson mechanism to avoid other projects to hard-code
the `freetype2_dep` variable name in their build definition. It
also ensures that meson does not mix system and subproject versions
of FreeType inside of the same project.
Also remove outdated TODO because `declare_dependency` was already
there.

* meson.build (bzip2_dep): Simplify.
We remove `static:false` from `find_library('bz2')`.
I don't know whether the previous code was a workaround for an old
meson bug, but at least with version >=0.55.0 (which FreeType uses)
it picks the shared library when both are available.
With this commit, file `freetype2.pc` no longer contains the full path to
file `libbz2.so`; instead, it correctly uses `-lbz2`. Note that this is a
meson bug is still present in the current version (0.57.0).

[sfnt] Additional checks for 'colr' table presence.
* sfnt/ttcolr.c (tt_face_get_colr_glyph_paint,
tt_face_get_colorline_stops, tt_face_get_paint): Additional checks

|
Add config option to test for 'COLR' v1 support in headers.
* include/freetype/config/ftoption.h (TT_SUPPORT_COLRV1): New macro
so that clients can test whether the FreeType checkout that they are
building against supports the 'COLR' v1 API. This is intended to be
a temporary solution until 'COLR' v1 support is released in a
FreeType version and such a check can be made by using the version
number instead.

and to populate the data members of each specific `FT_COLR_Paint`
subtype.
(read_color_line): New function to parse retrieved color line
information into an `FT_ColorLine` object, which has information
about the color line extend mode as well as an
