BTW, the last parameter in texture() (bias) is optional, so you might omit the 0.

Thanks for the input. There was a perfectly valid reason for texelFetch, but since I can't remember it's probably not relevant anymore. I removed it as well as integer reference in favor of mod. I also created a version using a permutation matrix instead of the if statement, but I have a hard time believing it "better", I added it to the question, care to comment if it's better than the if it replaces?
