having had to solve this at the application level recently (which was
a very distinct kind of pain), i'd suggest that the treeview needs a
2d focus map, very analogous to the 1d focus chain that exists at the
widget level. i'd actually go one step further, and say that the
widget level probably needs a 2d focus map as well.

if you don't use an actual data structure (which could be nasty
because you're effectively caching the structure of the model), then
you need to expose the concept of such a thing.
