* Add Post Processing Effects * fix events and shader issues * fix gtk upscale slider value * fix bgra games * don't swap swizzle if already swapped * restore opengl texture state after effects run * addressed review * use single pipeline for smaa and fsr * call finish on all pipelines * addressed review * attempt fix file case * attempt fixing file case * fix filter level tick frequency * adjust filter slider margins * replace fxaa shaders with original shader * addressed review
