Yes, Bernhard also told me that he has heard that Cairo is not as
advanced as libart yet and the gimp guys decided against Cairo yet.
They also think that a libart version in CVS does not have that
numerical problems anymore (which would solve the most part
of Skencil's problem with libart.)

Hard to judge from my perspective as I believe Skencil should keep
some of its own data structure and probably will have special needs
regarding transparency support and printed vector output.
Usually a vector drawing application as special needs and the design
of Cairo might not be up for it.

At least we should try at some point.
