A new Equalize command on the Image Modification dashboard, which equalizes nonuniform illumination.

Translucent colors for marking selected pixels, making it easier to see what's been selected. The opacity can be adjusted in the graphics menu. A -quit command line option, forcing ppm2oof to quit quietly after running a script.
Numerous bug fixes.
