I definitely do prefer names like those that actually describe the
different effect in more concrete, qualitative terms. That does seem
more useful than the existing distinctions, (where I personally wouldn't
choose anything other than "none" or "full" because it's not clear what
"slight" and "medium" even mean).
Behdad, any feedback here?
Meanwhile, it seems to me that much of this specification is actually
happening via fontconfig in practice, (and the same might be true for
the lcd-filtering configuration), so the actual cairo API here might not
be significant for many applications.
