<p>This function installs a "drag-motion" handler to the dest widget
to support auto-scroll when the dragged item is near the margin
of the destination widget. For example, when a user drags an item
over the bottom of a GtkTreeView, the desired behavior should be
to scroll up the content of the tree view and to expose the items
below currently visible region. So the user can drop on them.</p>
