>Graphics.UI.Gtk.ModelView.TreeViews provide special support for
 Drag-and-Drop such as hover-to-open-rows or autoscrolling. This module
 implements two utility functions that set and get a path and a model in a
 Graphics.UI.Gtk.General.Selection.Selection structure. These functions
 are thus useful to implement drag-and-drop functionality in a
 Graphics.UI.Gtk.ModelView.TreeModel. In fact, they are used as part of
 the default drag-and-drop interfaces of
 Graphics.UI.Gtk.ModelView.ListStore and
 Graphics.UI.Gtk.ModelView.TreeStore that allows to permute rows and move
 them between hierarchy levels.
