--- Comment #6 from alexhultman@gmail.com --- OpenSUSE 13.1 (GNOME) renders sharp text even though they have freetype 2.5 so obviously they have solved any issues they had.
<match target="font"> <test name="fontformat" compare="eq"> <string>CFF</string> </test> <edit name="hintstyle" mode="assign"> <const>hintslight</const> </edit> </match>
This seems like a good solution -> getting all CFF fonts covered instead of having to enter rules for every single font. I don't know how to test this and I'm still on Fedora 19 but it seems legit?
