I think we have to make this assumption or cairo will be worthless without
Render -- that includes all non-X environments. The only trick I see is
in having cairo track the size of the drawable; I don't have any great
ideas here as the library can't do this on it's own, and it will only
matter when you don't have Render, leaving the system prone to failure in
It might also be nice to have some kind of 'flush' operation which ensures
that the target drawable contains the rendering results.
