Ok. I'd like to hear from some authors what they think, then. I'll
leave the issue open for now.

Sorry, I meant ISSUE-42

I've clarified the text for 'background-break' in the editor's draft
as follows:

>> Proposal for 'no-clip' value for 'background-clip'.

Lots of modern designs like to break the visual box with graphics.
I think this feature would make that easier, so graphics wouldn't
have to be cut up and positioned precisely. My preference would be
to leave it in and get some feedback at least in the next working
draft if not in the CR.

Treating it as a radius defines what negative spreads do quite simply.
But I'm guessing from Brad Kemper's comments that sharp corners are
preferred? I'll clarify the draft to suggest that.

Ok. Left unchanged for now.
