That makes a lot of sense.  Oh, I'd also like to add

char *
cairo_image_surface_current_data (cairo_surface_t *surface, 
                                  cairo_format_t  *formatp,
                                  int             *widthp, 
                                  int             *heightp,
                                  int             *stridep)

(or some such) so you can just let cairo allocate the memory.
