Comment 3 for bug 1292073

Expected behavior:
By default, Ristretto zooms in when turning the scroll-wheel forward, and zooms out when turning the scroll-wheel backward.
This setting can be inverted by navigating to Edit -> Preferences -> Control tab, and check the "Invert zoom direction" check box.

What is actually happening:
After checking the "Invert zoom direction" check box it's still zooming in when turning the scroll-wheel forward and zooming out when turning the scroll-wheel backward.
