And a third filter for your enjoyment. Staying with the "old movies" theme for another day, this one gives you black and white. (Well, strictly speaking, from an artist's point of view, it's greyscale, but that's what we normally mean when we talk about black and white movies.)
This filter doesn't have any options associated with it yet - it just strips out all the colour information.
Usual disclaimers apply: this is really early dev code, not representative of final quality, and we don't have a release date for it.
