Well... the whole idea is to get rid of that interface and replace it
by something saner. Maybe I have already posted that in a previous
discussion, in my view we should have something like:
- QgsLibraryItem - base item, basically a node of the legend tree
- various item specializations: QgsLibraryLayer, QgsLibraryGroup etc
with some additional methods
- an entry point in QgisInterface for getting root QgsLibraryItem
We already have those QgsLibraryXXX classes, but they are derived from
QTreeWidgetItem and that's not acceptable for API.

A second step would be to move library view to GUI library so that
also 3rd party applications can use the legend (instead of just
accessing the instance within QGIS).
