TouchJoysticksnapStickToTouch Property

If true, the stick disc will snap immediately to the touch position when initially touched. This results in the stick disc being centered to the touch position. This will cause the stick to generate input immediately when touched if not touched perfectly centered. If false, the stick disc will remain in its current position on touch, and when dragged will retain the same offset. The stick's center point will be set to the position of the touch. The initial touch will not cause the stick to pop in any direction.
