Erk.  I forgot that you used it in atk.  is_expander is set to TRUE if
the row has children, and is_expanded is set to TRUE if it is expanded.
It should be relatively easy (if not a little inefficient) to query the
tree and model to find out which.  This is meant so that the pixbuf cell
renderer can have different images depending on the state of the tree
(ie, book open vs. book closed...)
