AtmosphereTransforms

“Atmosphere space” uses local up for the zenith so the horizon-detail parameterization concentrates texels at the viewer’s horizon. Azimuth uses a world-fixed reference so the terminator stays stable when tilting the camera.

world_from_atmosphere: mat4x4<f32> ,
atmosphere_from_world: mat4x4<f32> ,
