//Clarity by Ioxa
//Version 1.5 for ReShade 3.0

//>Clarity Settings<\\

//#include "ReShadeUI.fxh" Removed when porting over to Astray.fx Repo.
//Notes:

//The goal here is port and store this shader since the main repo is going away.
//I am taking over a few shaders I feel should be saved and don't have textures.
//The rest of the shaders will be moved to a other repo. That Ceejay.dk tells me.
//Any changes done to the shaders for now will be for compatablity. Other then that,
//I don't see any licenceing so I am worried about this since here is no due diligence.
//Anyways I think it should be fine and thank you Ioxa for a shader staple in ReShade.
//Also to anyone else if you see issues in the shader please report them to the AtrayFX repo.
//Thank you.
