Adds a new option to scale analog stick diagonal inputs, correcting for the drop off caused by modern controllers having a square pickup zone as opposed to the DS2 which was round and could sustain full input on diagonals.
A possibly cleaner alternative to axis scaling, so full input can still be achieved on diagonals without having to crank axis scaling and causing cardinal directions to max out noticeably before hitting the actual edge of the stick housing.
