Airglow/atmospheric scattering at night

Currently, the sky after sunset becomes completely dark. However, atmosphere is never completely dark and during night, when rayleigh scattering stops dominating, some phenomena appear like airglow or moonlight scattering...

In the demo shader `atmosphere/demo/demo.glsl`, when testing whether the view ray intersects with the ground: ```glsl p = camera - earth_center; p_dot_v = dot(p, view_direction); p_dot_p = dot(p, p); float...
