Comment # 1 on bug 1223434 from Martin Sirringhaus

I can confirm on GNOME as well. 

It seems like it's not about hinting, but antialias. If I comment out 
```
      <edit name="antialias" mode="assign">
        <bool>false</bool>
      </edit>
```
emojis are 'pretty' again.

Not sure, if this is a Firefox-issue or a font-config issue, though.

This seems related to: https://github.com/openSUSE/fonts-config/issues/12

Marguerite, could you maybe take a look please?
