I've looked a bit deeper, noticing that iTools on Unix does indeed
have depressed bitmap buttons, and found that the magic keyword
required under Unix (and not Windows) is /TOOLBAR (added with v5.6).
This will dispense with the radio button, and space the buttons close
together, indicating selection status by "depressing" them. Interesting
disparity between Windows/Motif, but I guess the Motif version is a bit
more consistent.
