[gradsusr] one colobar for multiple images

[Jeff Duda]

The trick I use is to set the plotting area to cover a very small corner on
the virtual page, display the field you want a color bar for, then display
the color bar using the appropriate arguments.  You can then use the draw
polyf command to draw a white/black filled rectangle over the very small
plotting window you just displayed over.
