/*************************************************************
LumaSharpen version 1.5.0 for Reshade 3.x
by Christian Cann Schuldt Jensen ~ CeeJay.dk
It blurs the original pixel with the surrounding pixels and then subtracts this blur to sharpen the image.
It does this in luma to avoid color artifacts and allows limiting the maximum sharpning to avoid or lessen halo artifacts.
This is similar to using Unsharp Mask in Photoshop.
Adapted to sfall by Mr.Stalin
