We can use Fontconfig to set per-font hinting and anti-aliasing
settings! :-)

We can't toggle the interpreter version directly through Fontconfig, but
at `full' hinting, the v40 interpreter should give the same results as
v38, especially with anti-aliasing disabled. I can't speak reliably
about the v35 interpreter because NixOS has always used v38 in the past.

I assume that "old windows fonts" means corefonts? Are you having
trouble with any other fonts besides PragmataPro? If you give me a list,
I can put together some samples to see if we can't find something better
for everyone.
