When Michael designed the 4.0 color tables, I stressed how nice and
simple the 3.0 format was, and that somebody was going to want the
old format. So I urged him to provide backwards compatibility. I
am happy to say that it is there. All you need to do is
set the environment flag: FORCE_GRASS3_COLORS and then
any color tables that are created will be written in that format.
I think a g.resample will force the color table to be rewritten as
well as the cell file itself.
