Seems OK. Not sure about the -is prefix on the getters, and would be good for smfr to peek.

Does this need to be exposed? We can compute this internally in GraphicsLayer while flushing.

There's some ambiguity here. Does m_isSeparatedPortal being true imply that m_isSeparated is also true?

You are right, probably not.

It's currently meant only to be valid when m_isSeparated is true. I don't want to merge it into an enum yet though, as depending on where things go, this may become non-separated requiring.
