Enables the stabilization of the shadow's edges. (default is <code>true</code>)
This prevents shadow edges from flickering when the camera moves.
However, it can lead to some loss of shadow quality in particular scenes.

 @param stabilize <code>true</code> if the stabilization has to be enabled and <code>false</code> otherwise.
