Urgh, I've had a look at the aterm source and the gtk source and it does
seem to be the only way to trap wheel motion.  I must admit that for a
while I was confused as to the direction of the mapping, which delayed
my understanding.

This is what debates are for.  You are completely right and now I'm also
100% sure of your solution.  Please keep working on your patch: I think
it's a good idea if we could integrate this into VTK.  An extra
interaction possibility is always welcome! :)

Thanks for your patience,
Charl
