/**
 * This subclass of {@link JTriStateTree} provides custom behaviour
 * for tooltips: ontological terms will now always get a tooltip that
 * displays the namespace for the tag, but plain text tags will still
 * behave as before - the way it is defined in the superclass (so that
 * the tooltip will only be shown if the tag does not fully fit into
 * the visible part of the {@link FilterTreePane}.
