;;; Commentary:
|
|
;;
|
|
;; Supporting Image display for Emacs 20 and less, Emacs 21, and XEmacs,
|
|
;; is a challenging task, which doesn't take kindly to being byte compiled.
|
|
;; When sharing speedbar.elc between these three applications, the Image
|
|
;; support can get lost.
|
|
;;
|
|
;; By splitting out that hard part into this file, and avoiding byte
|
|
;; compilation, one copy speedbar can support all these platforms together.
|
|
;;
|
|
;; This file requires the `image' package if it is available.
