Fortunately the only GUI programming I have done was FLTK, so I might
have some hope of deciphering it a little. In my previous app (nothing
to do with ITK) I observed that the updating from the widgets only gets
done 'when necessary' according to FLTK, which can be tweaked endlessly
it seems. I ws thinking of short circuiting that event-driven update
and including an 'update' button somewhere that would just update the
point set, and possibly the down stream calculations.
