;;; Requirements:
-;; Artist requires Emacs 19.28 or higher.
-;;
;; Artist requires the `rect' package (which comes with Emacs) to be
;; loadable, unless the variable `artist-interface-with-rect' is set
;; to nil.
;;; Known bugs:
-;; The shifted operations are not available when drawing with the mouse
-;; in Emacs 19.29 and 19.30.
-;;
;; It is not possible to change between shifted and unshifted operation
;; while drawing with the mouse. (See the comment in the function
;; artist-shift-has-changed for further details.)
