If that's the case (i.e. ALL of these toolkits assume that Button 4 and
5 events are triggered by the scroll-wheel) we could *maybe* do the
same, although one has to wonder what will happen on that odd mouse
where Buttons 4 and 5 are something totally different (e.g. thumb
buttons).  If you find anymore information about this, I would love to
hear.
