title: How to get CCSprite's size after changing scale
body: <p>This does not work:</p>
  
  <pre><code>CCSprite *testscale=[CCSprite spriteWithSpriteFrame:starFrame];
          testscale.scale=0.5;
  float starWidth=testscale.contentSizeInPixels.width;
          CCLOG(@"contentpixels: %f contentsize: %f",starWidth, testscale.contentSize.width);
  </code></pre>
  
  <p>The two  outputs in CCLOG both show the original pixel size of the sprite, not the size after scaling.</p>
  
  <p>Is there a way to get it <em>without</em> doing this?...</p>
  
  <p><code>float displayWidth=starWidth*testscale.scale;</code></p>
