Drag-n-drop to empty GtkTreeView

[Joseph <j-alan pacbell net>]

Hello,

I've gotten drag and drop to work with a GtkTreeView by replacing the
functions in the drag dest iface with my own, however none of the
functions are called when the tree is empty. Is there something
special I can do to handle d-n-d to empty trees, or should I just
install a drag handler for the tree's container?
