The other case I'd be concerned about is SDL or other framebuffer-
oriented drawing on embedded devices. I'm not aware of any actual uses, 
so this perhaps has no moral authority. But if, for example, I were to 
use cairo for a game on the n770, it would be tempting to draw into SDL 
surfaces since maemo isn't supporting a native, gtk-coupled cairo.
