I think you need to temporarily turn on decomposed color to get the
button background color correct. The bummer of Motif is that you
can't get depressed buttons in Exclusive/Non-exclusive bases, so this
routine helps us little. Instead, you always get a little diamond
next to the button, be it text or bitmap, to indicate selection
status. I've worked around this by simulating my own exclusivity and
changing the button value bitmap to look different when selected.
It's not ideal. I'm not sure if this is a Motif limitation or an IDL
limitation (buttons *do* depress when you click them).
