Support for visiting image files
Defines a file-name-handler hook that transforms visited (or inserted) image files so that they are displayed by Emacs as images. This is done by putting a `display' text-property on the image data, with the image-data still present underneath; if the resulting buffer file is saved to another name it will correctly save the image data to the new file.
