24 * An Icon contains the full pathname of its file and the DirItem for that
25 * file. Icons emit the following signals:
26 *
27 * redraw - the image, details or selection state have changed.
28 * update - the name or path has changed.
29 * destroy - someone wishes to remove the icon.
30 *
31 * Note that an icon may be removed without emitting 'destroy'.
