When a locked basic drawer's item quantity is fluctuating between 0 and positive, it is causing a lot of chunk updates which is most likely not necessary. For reference, this issue does not happen to the compacting drawer.

========================================

Also, do you mind back-porting these 2 commits for the re-rendering issue back to the 1.7.10 branch. I Know it is a obsolete branch, but when I tried to build it myself, it failed due to the missing dependency from mobiusstrip.eu, I have no clue which repo can replace for those files.

So, I manage to apply the patch to the jar through dirty bytecode editing, find out that this will break the fill level upgrade. That being said, I am still happy with the FPS improvement :)

Thanks
