Comment 8 for bug 802755

I'm not sure what Paul had in mind. The only route that occurs to me is for someone to arrange renaming of the all the files in the jp2.zip so they can become an orig_jp2.tar instead, and then modify the scandata to specify that each image should be rotated. Then the deriver would do the rotation while making a new set of processed jp2s from what will have become orig jp2s.
