Yeah, I think James missed a couple of critial words here.  What he asked 
me in IRC was whether cairo could expose reference counts for cairo_t and 
cairo_surface_t; cairo_surface_t already has reference counts inside, so 
that would require only an external 'ref' function.  Doing reference 
counts for cairo_t would require additional mechanism, but not that much.
