Better Blur
Not required in 24w11a and above!
Note: This resource pack requires a full game restart to load correctly. A restart is also required after disabling the pack.
Improves the blur algorithm used in 24w09a's new GUI.
The vanilla blur algorithm uses an unweighted average of surrounding pixels, which produces a blocky appearance (especially look around the hotbar):
This resource pack slightly modifies the algorithm to reduce the weight of further away pixels, which produces a much nicer blur effect:
This is the entire patch to the vanilla blur shader:

Given the `strength` and `totalStrength` variables are already in the vanilla shader but are unused, it seems possible that the blur algorithm was originally intended to be more similar to this resource pack.
I release this under CC0 1.0 Universal, although it probably isn't substantial enough to be eligible for copyright anyway.
