kr<|d }d}q 1 if one scrolls fast. Flicking the wheel
generates up to maybe 20 events with n up to 10 or more 1.
Macs use wheel down (delta = 1*n) to scroll up, so positive
delta means to scroll up on both systems.
X-11 sends Control-Button-4,5 events instead.
The widget parameter is needed so browser label bindings can pass
the underlying canvas.
This function depends on widget.yview to not be overridden by
a subclass.
