RITEG-VHS

This shaderpack is a post-processing port of a VHS filter pipeline I initially developed for my shader sandbox software [RITEG](https://untodesu.github.io/riteg); this shaderpack specifically includes the following effects: - Attempt to force the image into lower dynamic range with non-linear color curves - YIQ bleeding (not really made by me, see attribution) - Luminance and chrominance noise Attribution: - The shaderpack itself is based on [Base-Shader by Bestsoft101](https://github.com/Bestsoft101/Base-Shader) - The original pipeline and this port loosely base its VHS mangling on [VHS compression shader](https://www.shadertoy.com/view/tsfXWj)
