The problem is OpenJDK return value is different compared to oracle JDK. 
Only rotate X and. Zoom in/out events coming from the Mac trackpad.

Previously, we check e.getWheelRotation(), and it always returns 0 in the 
trackpad.  Now we check e.getPreciseWheelRotation()
too to have the zoom in/out and rotate X.
