// Khan Shatyr Minified JS ("Royal Marquee") (see http://en.wikipedia.org/wiki/Khan_Shatyr_Entertainment_Center).

// 
// Works pretty much like a marqee tag, but smoother. Uses jQuery animation for that.
// 
// Options:
// * pause:       The pause when changing the direction. Defaults to 300.
// * delay:       The duration for the animation (aka "speed"). Defaults to 2000.
// * max_kerning: Try to fit content up to this kerning. Defaults to -0.07.
// * easing:      Animation easing function. Defaults to 'linear'.
// 
// Features:
// * Doesn't scroll content that already fits.
// * Adjustable pause when changing direction.
// * Tries to fit content by reducing the fonts kerning.
// * Detects content changes and reinits the scroller.
