RadialFollow: Add cursor reset and tweak defaults

This change prevents bounce back in relative
mode and prevents cursor from getting stuck
in the corner in some fringe cases

 Inner radius defines the max distance the tablet reading can deviate from the cursor without moving it.

 ### Smoothing Coefficient
 Smoothing coefficient determines how fast or slow the cursor will descend from the outer radius to the inner.
 
 Possible value range is 0.0001..1, higher values mean more smoothing (slower descent to the inner radius).

 ### Soft Knee Scale
 Soft knee scale determines how soft the transition between smoothing inside and outside the outer radius is.
 
-Possible value range is 0..10, higher values mean softer transition.  
+Possible value range is 0..100, higher values mean softer transition.  
 The effect is somewhat logarithmic, i.e. most of the change happens closer to zero.

 ### Smoothing Leak Coefficient
 Smoothing leak coefficient allows for input smooting to continue past outer radius at a reduced rate.
