------

- Enhanced ambient occlusion is based on Capt Tatsu's ambient occlusion used in
  BSL Shaders:

I am not a graphics developer, I made this shader out of curiosity and
my personal use, but I think it is good enough to be shared.

I have not copied, but have tried to learn, adapt and modify
other people's ideas in favor of the shader.
