Another way to solve these problems would be to use ppm files for the
color icons, since ppm support is built in to Emacs.

Currently we do the following:

1. if display supports >= 256 colors, try low-color/IMAGE_NAME.xpm if it
exists
2. try IMAGE_NAME.xpm (color icons - requires libxpm)
3. try IMAGE_NAME.pbm (monochrome icons - support built in)
4. try IMAGE_NAME.xbm (monochrome icons - support built in)

Personally I think we should try looking for png images early in the
process, since that is the source format for the images
