Plasma part doesn't retain the original bugs :)

If you check a capture of the original demo, you'll see that the grayscale plasma isn't actually grayscale - that's because you fixed their bug ;)

Thanks Gargaj, I will check and analyze this later. (I'm currently writing about the techno part and it's probable that the plasma part will be the next one being analysed, it may result in changes in my implementation!)
