Optional parameter to test horizontal position of element on screen (as well as vertical).

[jshjohnson]

For example:

    var animate = new Animate({
        offset: [0.5, 0.25],
    });

This would test to see whether at least 50% of the elements height was within the viewport as well as 25% of the elements width. Useful for horizontal scrolling pages.
