Applied nebula lit shader to "planets" and asteroids
Modified gas giant shader to accept nebula lighting and to be a bit less crappy in general
Fixed raymarching depth sampling perspective distortion
New asteroid models
Asteroid belts have a custom width curve = tighter belts
Zone Generator uses color theory now
Zone gravity well is much deeper, filled with ambient glow
Gravity waves flow over time
Fog follows gravity waves
Gas Giant shader fixed, offsets distort albedo properly
Fog sample distances follow exponential curve
Fog noise offsets sampling position instead of subtracting density = more natural looking noise
Fog brightness fades out at max view distance
