I've made the config version a Float so that we can increment it without

The light map was calculating brightness incorrectly by accidentally offsetting the
sun angle by half a day.

Took me ages to realise that OpenGL actually just has a built-in fog feature. I spent quite
a while searching around the decompiled vanilla sources and shaders to find the exponential
fog equation to no avail (before realising that it's actually just a documented built-in
GL feature).

The sky plane is rendered exactly how it is in Vanilla (or so I hope).

This means that fixed time dimensions now have their sky/fog rendered correctly. The nether

Before this change, directional sunrise fog was incorrect when in camera 3, and you'd
get water fog when the camera was above water but the player was below

Still has a few issues, the main one being a weird color banding effect as the translucent
geometry passes through the fog, but at a distance it's not quite as noticeable. Will need
to revisit OIT at some point to make it a bit more accurate. Or alternatively I could just
optimize regular translucency rendering with smarter sorting.

Turns out it's just a 200x200x200 textured cube, the more you know. All the cool
shimmery effects are just a result of Moire patterns.
