+; 0.30 - some code cleanup
+; now uses the rotate plug-in to improve speed
+; 0.40 - changes to work with gimp-1.1
+; if the image was rotated, rotate the whole thing back when finished
+; 0.41 - changes to work with gimp-2.0, slightly correct text offsets,

+; TODO: - change the script so that the film is rotated, not the image

+; The script works on RGB and grayscale images that contain only

+; 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.
