Well, someone had this exact same problem on the XO yesterday.  Now, drawing a
pixbuf is inefficient in many other ways eve nif you cached a cairo image
surface: has to be uploaded to the X server and possibly blit'ed slowly to a
different format, which is exactly what would happen on the XO.

It's not like keeping a cairo_surface_t around solves most of the problem...
