Update to the current master branch so that is has
cairo_user_font_face_set_render_color_glyph_func().
I had to disable optimized builds on win[32|64] crossbuild setups
because they are now broken in the CI (something about cairo defining
_FORTIFY_SOURCE for optimized builds that MingW does not like).
In some cases we need to add additionl defs to build against icu if
icu has certain options configured.
ICU warns about this when building:
*** WARNING: You must set the following flags before code compiled against this ICU will function properly:
-DU_DISABLE_RENAMING=1
We can fetch these flags from the icu pkgconfig and add them if
required.
This fixes symbol errors if ICU is built without renaming.
We implicitly require it for building ragel subproject. This new version
requirement should satisfied in both Fedora 33 and Debian bullseye, and
not be too cutting edge for us.
If ragel 6.10 is not found, build it from source.
Seems to work, except that ragel uses exceptions and we configure
HarfBuzz build to not use exceptions, and I can’t find away to enable
exceptions only for the ragel subproject. I had to remove cpp_eh=none
from default options and try to disable exceptions in MSVC manually
(other compilers are already handled).
Ragel 7 is also not stable from upstream's point of view.
This uses “version” argument find_program(), which was introduced in
meson 0.52.0, so I raised the minimum required meson version
accordingly.
We don’t currently use it anywhere. It was used briefly for the
hb-fc-list tool, but this tool have not been built since 2015:

[util] Disable hb-fc-list for now
Until I figure out what to do about the API, and finalize
the tool.
It downloads a dependency from the internet, and in the same time not
used anywhere (one needs to explicitly call ninja benchmark), not even
on the CI (not sure if it that would make much sense since it does not
seem to ever fail).
When cairo comes from a subproject fallback it should still take
cairo-ft dependency, otherwise it miss freetype2 cflags.
Also update wrap file to use upstream repository now that meson support
has been merged.
This requires Meson >= 0.54.0 because cairo itself requires that version
and we use the new `fallback: 'cairo'` syntax without specifying a
variable name because cairo does not provide a variable name for
cairo-ft.
If we want to support a build with exception handling and RTTI
We should reflect that on library(..., link_language: 'c') also so for
now it is ok to just set it here to get MSVC support also and we
can remove hard coded flags later upon request.
One other concern over just relying on it is on when harfbuzz is used
as a subproject and the parent project hasn't provided the same options,
that should be resolved first I think.
