- New implementation of Film Grain that doesn't suck, so we can turn it up a nod by default. Supports RGB noise and shaping the distribution curve to control noise modulation. The previous implementation was just a placeholder, it was very basic. - Greatly increased Anti-Aliasing quality in default preset. - Include license headers to make clear that all my contributions are released on the public domain under the terms of the Unlicense. Anyone can do whatever they want with this.
