Hi Michael,

> Update Mac trackpad/Magic Mouse handling.

Two thumbs up on these changes! I use MOI on a MacBook Pro (without a mouse) & the V4 trackpad handling was inconsistent as you know. I haven't spent a lot of time with the beta but am noting with pleasure that I can use 2-finger drags to get panning reliably...used to be that sometimes it would get stuck and zoom instead. Now I have to "teach" myself to use it as intended! ;-}
