Subject: bug#22172: 25.1.50; Wishlist: There should be a way to say to Emacs that is should rescale all images with a certain factor

This has now been implemented and pushed.  Try playing with it a bit and
see whether it's annoying or not.  If it's annoying, we'll do something
else...

To test:

(insert-image (create-image "~/src/emacs/trunk/etc/images/gnus/gnus.png"))

and use the - + r o commands on the image.

Which reminds me: the `o' command doesn't really know what the image
format is, so it'll allow saving a png as foo.tiff.  It would be nice if
we could guide the user here.

Is there a way to make ImageMagick tell you what the format of the image
really is?
