Changes the Moon texture to look like a square version of the Moon in real life, while keeping a low-ish resolution to fit with vanilla.
This version also rotates the texture and fixes the phases so it is physically correct. It will probably look weird to you at first, but this is not an error. It looks best with shaders that have sun/moon angle (Set the angle to negative [your latitude] in your shader settings).
A version with the same phases/rotation as vanilla is available here.
