Ok, cool. I'll probably have something ready in a week or two.

A question for the list...

In the current Cairo egg resources like the cairo context must be 
explicitly destroyed (with cairo-destroy). Do you think it's a good idea to 
put these under control of the garbage collector by setting a finalizer to 
automatically free the resources? Possibly we could leave both options 
available, removing the finalizer if the resource is explicitly destroyed. We 
could also have a macro like (with-cairo-context name surface . body)

Another question - how do you remove a finalizer? I suppose
  (set-finalizer! obj (lambda (x) (void)))
might work, assuming it overrides the old one. Is there a better way?
