I think we would make individual requests for each one.  There's no point
in downloading all the LoDs for a 1x1 degree tile if we aren't going to see
them all, and the aim of WMTS etc. is that you just request what you need.

Making this up as I go along:  Yes - the idea would be that the ortho is
requested (from disk/http)  as FlightGear loads the WS3.0 scenery tiles.
This happens in a bunch of separate threads, and would only replace the
existing visible tile when it is complete.  So from a user perspective all
that would happen is that scenery would update a bit slower the first time
as we download the ortho.
