We have been expanding this experiment, and found that we are following
previous rob's post on cmap2rgb() etc.   Ok!, I got the problem right, I think.
The general solution, however, may not be so easy... Then, we'll try to solve
the problem under some local assumptions.

We have many 8bit depth greyscaled images, and want to display them on
8bit and truecolor (>=16bit) display.

We made a Plan 9 pic formatted file, begin with m8, and k8 :-).
The latter works fine on a truecolor display, but only 16 grey shades on
8bit display(pseudocolor).   This doen't change when we changed the
colormap to say /lib/cmap/c7291.56.

The former (m8), instead, works fine on the 8bit dosplay with colormap of
that c7291.56, but shows colors ^_^ on a true color display.  Where we 
should check?
