Title: Fix left/right scroll on OSX/trackpad

Relates to #1541

Speculative change - this fixes left/right scrolling for me. However
it is entirely possible that it breaks left/right scrolling for other
trackpads that issue wheel events - none of my other devices issue
left/right wheel events (and perhaps such devices are few and far
between). Submitted to see whether anyone else is impacted.
