[gembud] IMCBAR overlay

Howdy!

Surely this has been answered before, but I can't seem to find any answers
in the archives.  I am generating radar images via csh scripts and would
like to overlay an IMCBAR without any transparency such that maps don't
overwrite the IMCBAR.  Please see
http://meso-file1.tosm.ttu.edu/nexrad3/lbb_n0q_12.gif for an example.

Thanks!
