;;; Commentary:
;;
;; This module uses `before-string' overlay property to show icon
;; images instead of `insert-image', so don't delete such overlays
;; sloppily.  Here is a sample code to show icons in the buffer.
;;
;;(let (image icon from to overlay)
;;  ;; The function `find-image' will look for an image first on `load-path'
;;  ;; and then in `data-directory'.
;;  (let ((load-path (cons wl-icon-directory load-path)))
;;    (setq image (find-image (list (list :type 'xpm :file wl-nntp-folder-icon
;;					:ascent 'center)))))
;;  ;; `propertize' is a convenient function in such a case.
;;  ;; String must have one or more length to wear an image.
;;  (setq icon (propertize "any string" 'display image))
;;  (pop-to-buffer (get-buffer-create "*wl-e21-demo*"))
;;  (erase-buffer)
;;  (insert "   ")
;;  (setq from (point))
;;  (insert "-fj.wanderlust:0/0/0")
;;  (setq to (point))
;;  (insert "\n")
;;  (setq overlay (make-overlay from to))
;;  ;; Put an image.
;;  (overlay-put overlay 'before-string icon)
;;  ;; Put a mark to indicate that this overlay is made by `wl-e21'.
;;  ;; It is not always necessarily.
;;  (overlay-put overlay 'wl-e21-icon t)
;;  ;; Make it to be removable.
;;  (overlay-put overlay 'evaporate t))
;;
;; Note that a port of Emacs to some platforms (e.g. MS-Windoze) does
;; not yet support images.  It is a pity that neither icons nor tool-
;; bars will not be displayed in such systems.
