* libass dynamic library
it relies on fribidi, harfbuzz, fontconfig, libiconv
* Remove references to iconv and fontconfig
Because this port is currently Windows-only (Fribidi doesn't build on
Linux with vcpkg because of an issue with Meson), we don't want to worry
about FontConfig; DirectWrite should be enough.
* Freetype is important!
* Remove unnecessary fontconfig -- for real
* Remove unnecessary comment
This port currently only works on Windows because the dependencies of
the port (fribidi in particular) don't build on non-Windows platforms.
I made patch modifications to the source code because the Visual C++ C
compiler does not allow for non-constant-expression array indicesto be
used to declare a static array.
I've verified that this (1) builds on Windows and (2) works with a
sample test that's included in the libass github repo.
