Ok, I think I was perhaps misunderstanding the role of the ViewCSS
interface now that I think about it.  ViewCSS is meant to augment an
existing view to provide access to computed style information about that
view of the document, rather than being a view solely by itself.  Is
this correct?

I think this sentence isn't too unclear.
