Rayleigh v2#6285

What's the best way to test this? What am I looking for? |
Try to look at Venus or Titan, it should not have any sharp edges
A little bit, not that catastrophic drop from 50 FPS to 3 FPS using uniform arrays and doing mix() between its elements With my GPU, it was like 55 -> 51 FPS drop |

If this is slower, this would be an optional setting.
In the original PR @Mc-Pain mentions:

It's still an optional setting along with legacy atmosphere |
|
Will make some time to benchmark this soon, and I'd like to investigate the possibility of using a similar precomputation method for other objects in the scene. |

this approach is still slow and buggy - need to move calculating into vertex shaders - need to move water/lava flags into another texture map - vertexColor manipulating may break something

Experimental approach to improve rayleigh shaders:
Might be slow, but still accurate pre-calculated density LUT's and synced models within physics and graphics engines.
