One note for rgb's in xpm's.

When I wrote library for images and first I used xpm's as inserting
and extracting format, I found that there is no way (without
/usr/lib/rgb.txt) to get out RGB values from the xpm API without 
connection to the X server. I needed this for calculating color-
distancies (normal-rgb), when unifying color set to one image. 

So I decide to use ppm format for the file. And use pbmplus
package to conversion.
