SwipeGestureRecognizerDirectionThreshold Property

For set directions, this is the amount that the swipe must be proportionally in that direction vs the other direction. For example, a swipe down gesture will need to move in the y axis by this multiplier more versus moving along the x axis. Default is 1.5, which means the swipe down gesture needs to be 1.5 times greater in the y axis vs. the x axis. Less than or equal to 1 means any ratio is acceptable.
