Detailed Description

Analog axis deadzone filtering.

Axis is scaled appropriately, so position is continuous from -1.0 to 1.0:

       |    / 1.0
       |   /
     __|__/
    /  |
   /   |--| Deadzone

-1.0 / |

After deadzone filtering, the value will be:

• Negative in the interval [-1.0, -deadzone)
• Zero in the interval [-deadzone, deadzone]
• Positive in the interval (deadzone, 1.0]
