Custom PPSSPP shaders

[LunaMoo]

Really just redownload, function for gamma was nowhere close line 456 so I'm guessing you used some outdated version from before I added some new effects. Yeah I have a somewhat bad practice of not versioning my shader;p, but the link while always same, is getting updated whenever I change anything and I usually write when I'm updating it.

Also Gamma never used any ints for anything and I don't remember correcting anything in it since it wasn't copy pasted effect, really it's just one line of code that I wrote after reading how gamma should work. The only reason it even used mix through is because I forgot to remove it while reorganizing how the shader works, it wasn't using int at my file, so really don't know how you got it there, but removed that line completely just now along with the effect mentioned earlier.;]
