  * This Filter does basically the same as a PointLightShadowRenderer except it
  * renders the post shadow pass as a fullscreen quad pass instead of a geometry
  * pass. It's mostly faster than PointLightShadowRenderer as long as you have
  * more than about ten shadow receiving objects. The expense is the drawback
  * that the shadow Receive mode set on spatial is ignored. So basically all and
- * only objects that render depth in the scene receive shadows. See this post
- * for more details
