'repeat' means to simply tile the image as for background-image.
Since it's not yet specified where to anchor the image in this case,
you'll have to ask Dave Hyatt what he did.

If you're referring to
Viewing in the GIMP, I'm not seeing the problem you describe.

The rest of these are all very good points, unfortunately I don't have
answers for you. My suggestion is that you find out what Safari does,
and if it makes sense, implement that, and if it doesn't, ask Dave Hyatt
about it. We would have to do the same thing for the spec anyway, since
Safari implemented 'border-image' without first bringing up these problems
in the spec for discussion and without using a vendor extension. :(
Let us know what you find out, so we can ask Bert to put it in the spec
when he gets back.
