[Bf-committers] User Preferences Option for Multitouch Gestures

Patch reviewed -- looks good to me! For the most part...

Doing this in the WM has the additional benefit of affecting all
platforms, not just MacBooks. Yay!

Posting a GHOST event is an okay solution like you say, but might as
well go for the best, right? Which WM event type is generated in
response to a GHOST_kEventWheel? Just make one of those and let the
rest of that function handle it in the usual way. I'm guessing
wm_event_add_ghostevent puts things at the end of the queue, so the
(new) wheel event would be processed after events that actually
happened later. Does this matter? Maybe, maybe not. But it's simple to
avoid the issue by constructing a WM event instead.

Hope this was helpful!
