title: getting wrong coordinates of child sprite
body: <p>First of all thumbs up to Nicolas for his great engine. </p>
  
  <p>What I a doing is...
  1) I created a sprite, lets call is a parent sprite
  2) I created another sprite, lets call it child sprite
  3) I set child positing using convertLocalToSceneCoordinates
  4) I rotated this child sprite to -90 degree
  5) I Added this sprite to parent sprite and finally added parent sprite to scene</p>
  
  <p>Now its looking fine and moving along with parent but when I try to add another sprite at the position of child sprite it give me wrong coordinates. i.e X and Y.</p>
  
  <p>Please tell me how to fix?</p>
  
  <p>code:</p>
  
  <pre class="lang-java prettyprint-override"><code>mRocketPod = new RocketPod(0, 0, this.mTRRocketPod);
  float points[] = mRocketPod.convertLocalToSceneCoordinates(119, 10);
  mRocketPod.setPosition(points[0], points[1]);
  mRocketPod.setRotation(-90);
  mBossEarth.attachChild(mRocketPod);
  </code></pre>
  
  <p>It will give me wrong coordinates of mRocketPod.</p>
