Fix for 26.40

[IndeedItzGab]

I removed the rounded clouds terrain in this branch incase my code isn't good enough.

• Fixed aurora at night time.
  • Problem: FogColor no longer return a value as expected in Clouds material. However, it works as expected in RenderChunk (I have not tested FogColor from other materials)
  • Solution: Instead of using FogColor, we use TimeOfDay as an alternative since it is time accurate than fog color. Also allowing the aurora to be compatible with some texture packs or addons that manipulates fog color.
• Fixed dimension detection
  • Problem: As of now, I've checked DimensionID, WeatherID, and BiomeID (maybe all materialID) are not working.
  • Solution: I tested FogColor uniform and it is still working. Therefore, we will go back to the old method of detecting dimensions again.
• Fixed rainbow underwater
  • Problem: Prolly precision issue with a certain GPU
  • Solution: Added conditional if/else statement if the camera is in underwater or not. I expect no branching is going to happen since every rendered results are going to be the same per vertices/fragments.

I'll test all override uniforms to all materials that newb shader used later.

Uniform reference, uniform marked as non-upgradable might be broken (from veka):

resolving #99 and #100

I forgot to change the config.h to soft clouds, will be changed later after I fixed the white cloud

[IndeedItzGab]

my bad there are no white clouds at night time :)

I was just using the calculation where it makes the night darker as soon as it hits the expected value in my variant, making newb clouds lighter after sunset/before sunrise.

Fixed rainbow underwater
Problem: Prolly precision issue with a certain GPU

This is not precision issue with some GPUs. This is just overlapping with my rain detection logic. If you are underwater rain value becomes > 0

Fixed aurora at night time.
Problem: FogColor no longer return a value as expected in Clouds material. However, it works as expected in RenderChunk
Solution: Instead of using FogColor, we use TimeOfDay as an alternative since it is time accurate than fog color. Also allowing the aurora to be compatible with some texture packs or addons that manipulates fog color.

I'm okay with this

Fixed dimension detection
Problem: As of now, I've checked DimensionID, WeatherID, and BiomeID (maybe all materialID) are not working.
Solution: I tested FogColor uniform and it is still working. Therefore, we will go back to the old method of detecting dimensions again.

I'm okay with this also

But I can't merge this PR. It needs some more refactoring

[IndeedItzGab]

• Added ActorMultiTexture support for 26.40 changes and removed unused uniform "Day" to all other materials and detection.
• nightFactor was adjusted for aurora borealis to properly sync it with newb's night time. (Before it was showing on sunset/sunrise time)

[devendrn]

remove this?

[devendrn]

undo this

[devendrn]

pass env.dayFactor to function. handle masking of aurora inside it. should be like:

renderAurora(cloudPos.xyy, t, env.rainFactor, env.dayFactor)
