The biggest beef I have with the GTK wheel handling is that the use of
button4 & button5 as the wheel events is hardcoded in gtkmain.c:

      if ((grab_widget == event_widget) &&
	  (event->button.button == 4 || event->button.button == 5))

And this fails for people that have complicated mice where it would be
better to have buttons 1-5 be 'real' buttons and 6-7 be the wheel.
