Passing two values to jQuery Animate for backgroundPosition
<p>I need to animate a background image using backgroundPosition.</p>

<p>The problem is, if I animate on the X axis, the value passed by default to the Y Axis is CENTER.</p>

<p>This causes the image to jump vertically. I've seen some plugins to help alleviate that, but I'd like to keep the code as lean as possible.</p>

<p>Now that jQuery 1.8 includes new animation options, is there an easier way to do this? I need to apply easing.</p>
