LunaMoo Scalable Shader (fxaa, gaussian 8.0, xbr variant 2):

I noted in my shader those effects shouldn't be used together;p, heh I don't know why I even bother, noone reads it.
Also upscaling shaders require extra switch in ini file, which also is noted in the shader. Such combination results in non working xbr(if xBR was actually activated as variants doesn't do anything on it's own) or gaussian blur.
