Interesting. As I expected, it doesn't actually produce a very 
convincing effect; it merely wraps the image, and then does some 
cross-fading. The result is a very visible transition. (Still, at least 
they made it circular, eh?)

I still don't see how it's possible to take an arbitrary image and make 
it properly seamless.

As an aside, I'd never noticed the Filter menu before. There's quite a 
lot of stuff in there...
