Unofficial fork of Phosphor for 1.12

If Phosphor has made an improvement in performance for you, please consider pledging to my Patreon! Every pledge goes directly towards funding development and allows me to continue making Minecraft mods.
Phosphor is a free and open-source Minecraft mod (under GNU GPLv3) aiming to save your CPU cycles and improve performance by optimizing one of Minecraft's most inefficient areas-- the lighting engine. It works on both the client and server, and can be installed on servers without requiring clients to also have the mod.
For more information about how these results were obtained, please see my writeup on the benchmarking methodology.
Phosphor is designed to be as minimal as possible in the changes it makes, and as such, does not modify the light model or interfaces of vanilla Minecraft. Because of this, Phosphor should be compatible with many Minecraft mods (so long as they do not make drastic changes to how the lighting engine works.) If you've ran into a compatibility problem, please open an issue!
Phosphor makes a variety of modifications to the vanilla lighting engine in order to improve performance. The key highlights can be found below.
This list is still incomplete and a technical writeup of how Phosphor achieves such significant gains is in the works.
