Right.  I think that's an obvious thing to put in `image-map' to make it
easier to change the size of a single image.

(It's not just in image-mode -- that map is on all images inserted by
`insert-image'.)

I don't have a mouse myself, so it'd be nice if somebody with one
created a patch so that they could test it.  image-map is in image.el.
