Clearcoat can disable texture normals

Also:

* terrain gimmick
  * makes some hardcoded shit into params
  * add alternative normal evaluation methods
    * stochastic method gives best results without getting into analytic
      normals
  * add FBM noise texture slot to improve perf
  * add initial raytrace to sphere
    * stabilizes appearance as camera moves
  * add backtracking
    * eliminates sharp lines without sacrificing perf
* fog 00 can render on a plane now, in addition to cylinder
* add epilepsy protection filter
