Things to do:

1.  Add slide show capability, single image viewing from command line

2.  Add JPEG, Sun Raster, Portable PixMap, RIX image support.

3.  Add configuration file capability, color selection capability,
    and configuration editing window (colors, standard toggles, sort modes,
    etc)

4.  Add mouse support of some kind

5.  Add support of BGR and RGB truecolor display types

The next two items are REAL low on the priority list, and may not be
implemented.

5.  Add full GIF89a support (at this point, should be little more than
	expanding the viewer and image descriptors, and adding support in
	the ShowPic function).

6.  Add image save capability.
