Fix #9195 It looks like vf_vibrance.c is similar to https://github.com/zachsaw/RenderScripts/blob/master/RenderScripts/ImageProcessingShaders/SweetFX/Vibrance.hlsl and https://github.com/kevinlekiller/kwin-effect-shaders_shaders/blob/main/Vibrance.frag Originall written by Christian Cann Schuldt Jensen ~ CeeJay.dk. They use same matrix coeff.
