Face Node
The Face node outputs a positive value of 1 if the rendered surface is facing the camera or a negative value of -1 if its facing away from the camera.
NOTE: This node initially was only valid over fragment ports as it uses a face semantic over the fragment function signature to get the value. Now it also work on vertex ports but at the expense of additional instructions as it needs to be manually calculated and its not as precise as the one given by the face semantic.
