/**
* If you'd like the inbetween values in a tween to always get rounded to the nearest integer, use the roundProps
* special property. Just pass in an Array containing the property names that you'd like rounded. For example,
* if you're tweening the x, y, and alpha properties of mc and you want to round the x and y values (not alpha)
* every time the tween is rendered, you'd do: <br /><br /><code>
*
* TweenMax.to(mc, 2, {x:300, y:200, alpha:0.5, roundProps:["x","y"]});<br /><br /></code>
*
* <b>IMPORTANT:</b> roundProps requires TweenMax! TweenLite tweens will not round properties. <br /><br />
*
* <b>USAGE:</b><br /><br />
* <code>
* import com.greensock.TweenMax; <br /><br />
*
* TweenMax.to(mc, 2, {x:300, y:200, alpha:0.5, roundProps:["x","y"]}); <br /><br />
