It would probably be a good idea to add support for some kind of
"simultaneous preview" to the nxml-mode when editing an SVG, such that
it creates an auxiliary buffer in image-mode and updates it e.g. when
you save the file.

The same probably holds for other similar text+image formats, like XPM
and PostScript.

Maybe it should be some kind of `image-minor-mode` which lets you either
switch between `image-mode` and some other mode (like now) or display
the image in an auxiliary buffer.
