The latest major release of the cairo C lib changed the API to return an
int status code for a C function that previously returned void.

c2hs guarantees us some degree of cross-language type safety and caught
this api change for us (by turning it into a Haskell type error).

I expect the updates to work with the new cairo api are in the gtk2hs
darcs version.
