I've not even heard of the Thumbnail Managing Standard.  Does it deal with
transparency?  Or is it a tangential question?

I guess you can delete ~/.emacs-thumbs since thats no longer used by
thumbs.el.  Unifying them presupposes an understanding of the requirements.
By all accounts both thumbs and tumme are immature, so I'm not sure that we're
