More live filters

[kirk23]

1.  pattern / warp offset as live filter over a group without necessity to rasterize it

2. Sobel filters like  normal  and depth image to curvature/cavity

4. depth to SSAO

5. depth to normal map

6 normal map as vector to deform/displace another "linked" layer

7. same as #6 doing it in  several iterations loop,  fading in  each next iteration
