Water Shader Update & Atmosphere Added

I reintegrated the atmosphere shell/shader and updated the water shell with a heightmap of the terrain under it so I can have the water depth affect the transparency and color and I think it adds a lot - although now everything looks tropical - which I don't mind.

Water Depth Effects:

Also I made my underwater texture have fake caustics (static) on them which is subtle but nice:

And here are some pictures of the atmosphere and water shader together from various spots on the planet.

- I pretty much eliminated banding in the generated terrain texture images by increasing the resolution of my terrain height maps from 8bit to 16bit.
- The atmosphere still has problems and needs tweaking - there is no sun and the sky to space transition is too abrupt amongst other things.
- PSSM VSM shadows slowed the frame rate down too like 30-40 fps so I left them out for now.
- I need to solve the issue of how noticable texture repeating is from up in the atmosphere and I need to add some noise to the texture generation to make things more interesting.
