Details

Current design adds a member variable called mCrossBoundaryRange in nsRange to keep track of the real endpoints (a.k.a, endpoints that can cross the boundary). And we return the collapsed endpoints (nsRange::mStart, nsRange::mEnd) when needed.

Ideally, we don't need to keep the collapsed endpoints, we can always keep the real endpoints. We can use a bool or something to indicate that this range is collapsed and return a collapsed endpoint when needed.
