Multitouch trackpad 2 fingers gestures implementation
- 2 fingers scroll (MOUSEPAN / GHOST_kTrackpadEventScroll event) pans/scrolls the view
- 2 fingers pinch (MOUSEZOOM / GHOST_kTrackpadEventMagnify event) zooms the view
And in 3D view:
- alt + 2 fingers scroll rotates the view
- 2 fingers rotation (MOUSEROTATE / GHOST_kTrackpadEventRotate) orbits the view.
The implementation uses a new GHOST event type: GHOST_kEventTrackpad, that is then dispatched as Blender MOUSEPAN, MOUSEZOOM
or MOUSEROTATE events.
This is currently fully implemented for OSX (GHOST Cocoa fires the new events), with auto-detection of the source peripheral, so that a regular mouse still sends MOUSEWHEEL events.
