    Anyhow: in Emacs images are either overlays (in which case it is
    impossible to copy them anyway) or text properties.  While there is
    the special case of empty overlays also, in general an image covers
    an underlying text.

When you copy text that includes image properties, these properties
will either be kept or discarded depending on yank-excluded-properties.
Perhaps we should make that include `display' in some cases.
