I agree - however it would be awfully nice if I didn't have to walk the tree
at all, but instead could give you a template describing the capabilities
that I need setting. I need to be able to do geometrical hits. Not
everybody does. But having to post walk the tree to set the capabilities is
both inefficient and reasonably tricky for anyone who doesn't really want to
know the insides of the geometry.
Otherwise Justin, thanks for all of your efforts on an excellent project.

You might want to be careful here. We set most capability bits
beforehand, so you might be wasting effort.

How

The current loader interface has a very fuzzy definition about that. As
is, we don't have a way of telling you when the load is entirely
finished. We don't have an answer that is useful for you unfortunately.
Alan and I have spent quite a bit of time chatting about the loader and
various performance optimisations during the last week. We think we
have lots of stuff to do and some tricks to play. That work will likely
start in a month or so, but the end result is that you shouldn't need to
worry about this sort of thing then. We expect that it will take 4-5
months of development before that is complete.
