Unofficial backport of Sodium with a toggle added for planar fog. This build contains a number of upstream changes, and additionally makes the entity culling option have no effect on the entity count in the top left of the debug hud, so speedrunners can now exploit that ("microlense") with entity culling on. On the other hand entity culling now disables the blockentities entry in the rendering section of the profiler, so it'll need to be off if you want to exploit that ("pie ray"). This is to prevent the option giving any sort of advantage over vanilla for locating chests and such.
