[perlun]

I'll take this one, PR coming up in a while.

[nox]

Thanks!

[wafflespeanut]

@perlun has contributed a fairly good amount of stuff to servo, so I think it'd be better if we leave this for the newcomers (unless this should be fixed ASAP)

[nox]

It's mostly grunt work and there is quite a massive amount of them currently, I'm not sure it matters who does it.

[perlun]

@wafflespeanut - thank you for that. 😄 I'm halfway done with it so I'll think I just finish it this time. Next time, I'll try to leave the low-hanging fruit for others. 😉
