'position_tex_color_normal.fsh' and 'position_tex_color_normal.vsh' are no longer need in 1.21.2 and up
'rendertype_clouds.vsh' is no longer needed for 1.21.2 and up, they finally fixed the cloud offset! Yay!

'rendertype_clouds.fsh' Applies the fade.

We create fogFactor by smoothsteping the distance by a min of 200, and a max of 350.
Now we invert that fogFactor, 1.0 - fogFactor
and then multiply the alpha in the output color.
