title: Animate rotate negative (jQuery GSAP)
body: <p>I'm having a problem with animating transform rotateX and rotateY. I'm using the GSAP jQuery plugin.</p>
  
  <p>Basically executing this:</p>
  
  <pre><code>$(element).animate({transform: "rotateX(-180deg)"});
  </code></pre>
  
  <p>has the same effect as executing:</p>
  
  <pre><code>$(element).animate({transform: "rotateX(180deg)"});
  </code></pre>
  
  <p>I do have perspective set up, in case you were wondering.</p>
  
  <p>Is there a special way I have to define negative values or is this a bug?</p>
  
  <p><strong>UPDATE:</strong> I have found a property "shortRotationX" and "shortRotationY" mentioned here: <a href="http://codepen.io/GreenSock/pen/ydIgf" rel="nofollow">http://codepen.io/GreenSock/pen/ydIgf</a></p>
  
  <p>However this seems to be a temporary workaround. I would like to know what the correct way is to animate rotations with jQuery + GSAP.
  Thank you guys!
