- * - Stencil Actors can be used to influence the result of hits on renderable actors within a layer.
- * If a Stencil Actor exists on a layer and that Actor is marked visible then a successful
- * hit on a renderable actor can only take place in the area that the stencil Actor marks as visible.
- * The hit can be in any Stencil Actor in that layer, but must be in the region of one of them.
- * Stencil Actor inheritance behaves as with rendering in that any child of a Stencil Actor will
- * also be considered a Stencil Actor.
- * Non-renderable actors can be hit regardless of whether a stencil actor is hit or not.
