Sorry, I mis-stated my problem. I'd like dialog to come up with same
widget values next time GIMP is started up.

Thanks, I think it I read that bit in the Scheme manual and forgot

Sorry, mis-stated by requirement.
parasites are just what I need. Can't find much about them.
(list "WRF_BIT_WIDTH" 1 (number->string bit-width)))
First list member: parasite ID string.
What's the second list member? Flags, I understand from one search
result I found. Used?
Third list member: parasite value (must always be a string). So an
RGB colour value would have to be stringified. unstrbreakup maybe?
Generally: do all the gimp-*-parasite-attach methods suffer from same
bug, so should be reapplied til they work?
Public speaking is very easy.
