Fansliders are lovely ideas, but the current implementation is pretty
crappy, and I haven't look at the code in years and didn't have a
clear idea about what I was doing with it last time anyway. Now that x
composite is a lot more common it would be easier. I'm surprised
Thorsten hasn't jumped in to the knob discussion yet. If anyone else
wants to fix fan sliders feel free to give me a yell.

I still think knobs are pretty evil though. :)
