A Vector2 containing the most recent values from the Gamepad's right axis stick.
This is updated automatically as part of the Gamepad.update cycle.
The H Axis is mapped to the Vector2.x
property, and the V Axis to the Vector2.y
property.
The values are based on the Axis thresholds.
If the Gamepad does not have a right axis stick, the values will always be zero.
