; Rounds the corners of an image, optionally adding a drop-shadow and
; a background layer
;
; The script works on RGB and grayscale images that contain only
; one layer. It creates a copy of the image or can optionally work
; on the original. The script uses the current background color to
; create a background layer. It makes a call to the script drop-shadow.
;
; This script is derived from my script add-shadow, which has become
; obsolete now.
