Rayleigh v2

[Mc-Pain]

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.

What's the best way to test this? What am I looking for?
You mentioned that it might be slow but do you mean slower than the existing version?

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:

This also makes water reflect rays from skylight, bringing realistic Earth colors.

[Mc-Pain]

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.
