I think we should leave it in the L4 draft; we all agree on what the syntax
should be, but figuring out exactly how it works seems to require a bit more
discussion. Also, the CSS2.0 version did not include a spread radius, and
since this spec is the replacement for that, I think we should just include
the 2.0 features. That way it's more obvious that there are implementations
that don't support the fourth value.
