- Add wxWidgets patch to support Cocoa's NSEventTypeMagnify from the Magic Trackpad. 

This was originally submitted by Jared Boone in http://trac.wxwidgets.org/ticket/14322
    and has been updaetd to apply cleanly to wxWidgets-3.0 (and less cleanly to 3.0.1 an 3.0.2).
    The ticket is marked as accepted but not scheduled, so no idea if it will ever make it in.
