Hi James,

Thanks for the update and for looking into this issue.  I am glad to see
there is progress on this issue.

I hope we can get a timely resolution on this bug and #839314.  If not,
I will request that cairocffi drops its Build-Dependency and then remove
xcffib plus haskell-xcb-types from testing.

Thanks,
~Niels
