Because of the success of the qt plugin project, it is now feasible to
consider using a QGraphicsScene to render Leo's tree "by hand". It
would be one way to get the same kinds of high-level memory
optimizations provided by leoTkinterTree. It's not likely, perhaps,
but it's something to keep in the back of my mind...
