This is indeed how I interpreted them. Moreover, these two functions
are almost exactly the same extensions that we added to OOGL to get
WebOOGL (with "<" denoting inlines, and ">" denoting anchor groups).
So I think there's a good deal of consensus on the functions, if not
the names.

I must admit I do like your names better (I think Gavin was just
trying to stay close to names of related items in Inventor).

And yes, handling the inlines efficiently could eventually require
some fairly sophisticated "level-of-detailing", for example based on
visibility as well as scale.
