that makes sense; the call could actually include the surface size as 
parameters; presumably the calling application would know that information 
so that cairo could avoid a round-trip.  We could then ensure that this 
information was used on Render servers by clipping to the specified 
rectangle (perhaps only during debugging though; extraneous clipping is 
not free in the X server).
