Make Overview swipe gesture independent from "Natural Scrolling" setting
Feature summary
The "Natural Scrolling" setting currently changes the direction of the Swipe Gesture needed to enter the Overview.
We should decide if we want this switching behaviour as it might cause troubles for people coming from Mac OS.
On Mac OS the Overview / Exposé gesture is always Swipe Up, independent from the Natural Scrolling setting.
How would you like it to work
The Natural Scrolling setting should not influence the Swipe Gesture Direction to enter / close Overview.
