title: cocos2d-html5 onMouseDown, how to get converted position in browser?
body: <p><Br></p>
  
  <p>In cocos2d-html5,<br>
  I can get mouse event using this method,</p>
  
  <pre><code>onMouseDown:function( event ) {
      var loc = event.getLocation();
      console.debug( loc );
  }
  </code></pre>
  
  <p>So in Chrome browser console, I can see the clicked location.<Br/>
  but, the location is not position of the cocos2d screen. <br>
  the location is browser size relative position. I mean,</p>
  
  <p>reference image~

  But, I want to get cocos2d-screen relative position like this,</p>
  
  <p><img src="https://i.stack.imgur.com/jPh8q.png" alt="enter image description here"></p>
  
  <p><br/></p>
  
  <p>is there any way to get the position directly or <br/>
  any way to convert into the location?</p>
  
  <p><br/>
  My project is for browser based not simulator or phone. </p>
