When background images can be displayed on arbitrary positions in the
buffer (I understand that this is possible with Miles' code) they
could be used for other fancy things, not only for decorative
background images in the actual sense of the word. I am thinking of
widgets implemented as pictures behind the text or similar things.

Moreover, as soon as some kind soul implements a way to change images
in the image cache directly, this type of background images could
allow simple vector graphics. Like drawing arrows from one part of the
text to other parts, drawing a vertical ruler line and such stuff. :-)

I assume this is about the XPM images for the toolbar and the splash
screen?  I would like to do the conversion as soon as I have a
GNU/Linux on my new computer; this will be in a week or two
(university has just started again ...).

But: While replacing the XPM with PPM would have the benefit that even
an Emacs compiled without XPM support could have coloured icons on the
toolbar, getting rid of the PBMs would cause a problem for mono
displays (black&white, not grayscale), wouldn't it?
