Hi Fabian,
I'm adding your changes, and we should agree on an indent style. After
skimming indent(1) I propose to use indent -kr.
I'm not giving up on the brightness thing unless I can be proven the
split screen isn't worked around with it, but we should add a flag for
enabling/disabling it.
I'd just like to add the following (don't take me wrong, I'm not mad or
anything even closer :) ):
You can't really replace...
	 * Copyright © 2008 Rui Miguel Silva Seabra <rms at 1407.org>
	 *
	 * Inspired upon Chris Ball's rotate, this is a totally new rewrite.
With...
	 * Copyright (c) 2008 Fabian Henze <hoacha at quantentunnel.de>
	 *
	 * Based on Rui Miguel Silva Seabra's rotate, but more optimized for
	 * speed memory usage and a better algorithm.
So in the mix and matching I'm doing, I'm writing:
	 * Copyright © 2008 Rui Miguel Silva Seabra <rms at 1407.org>
	 * Copyright © 2008 Fabian Henze <hoacha at quantentunnel.de>
	 *
	 * Inspired upon Chris Ball's rotate, this is a totally new rewrite.
Fine with you?
Can you get a google mail account (just for having an account on code.google.com)
so I can add you as a project member?
Best,
Rui
