Actually, look_at is provided to avoid all of those rotational calculations
and make it easier to aim the camera with more precision. The 'direction'
keyword is the original and more traditional way to specify the amount of
zoom. I prefer the newer 'angle' keyword. But for photographers and the like
who are more used to thinking in terms of focal length, fstops, and whatnot,
I suspect 'direction' is easier to deal with.
