+A control with a continuous range of values.  A button is treated as either 1
+or 0.  Axis values are mapped to absolute value.
+
+Two smooth controls can also be paired to each other.  Motion on one control of
+the pair will cause negative motion on the other.  This works best when the
+controls are bound to the opposite sides of the same joystick axis.
