Hmm, this surprised me but I just confirmed it. In older versions of
gtk, if I recall correctly and maybe Steve can confirm, you could get
scroll events as buttons 4 and 5 on button_press_event, but it looks
like you now have to explicitly connect to scroll_event apparently.
mpl should encapsulate the scroll_event across backends, me thinks.
For now you should be able to do
canvas.connect('scroll_event', yourfunc)
but these will be GTK events and callbacks so they will have a
different signature than the mpl callback and will not have the mpl
metadata like xdata and ydata.
