Optimize Light Recalculations The server triggers light recalculations even if the new block is the same as the old block. At this time, BlockData Properties do not impact light calculations. So the only way light should change, is if the block itself changes from 1 block to another. Additionally, as of 1.13, water now only blocks 1 light level instead of 3, meaning that light level decreasing is the same as air. This means, transitions between water and air also do not need to recalculate light, which saves a TON of updates caused by fluids flowing.

Subject: [PATCH] Optimize Light Recalculations
The server triggers light recalculations even if the new block
is the same as the old block. At this time, BlockData Properties
do not impact light calculations.
So the only way light should change, is if the block itself
changes from 1 block to another.
Optimize some light chunk access light calculations repeatedly looks up the same chunk while going down on the Y access. Pass the chunk to it to skip many round trips to the map lookup process. while the gains arent as big since we have last access cache, it should hopefully avoid many callstacks of depth and improve inlining, as well as avoids entering a synchronized code block. The avoiding of entering synchronized section is the main goal here.

Also optimizes to not repeatedly look up the same chunk for
light lookups.
