title: Getting custom annotations (Ti.Map) pixelated
body: <p>I've tried with different images in several resolutions (50x30, 70x50, 100x70). All of them are good enough out of titanium app, but I cannot get custom pins without pixel effect into the app. </p>
  
  <p>I'm using Titatnium 3.0. </p>
  
  <p>How can I make my custom images to obtain a best visual result?</p>

  <p>Code:
  <code></p>
  
  <pre><code>var annot = Titanium.Map.createAnnotation({
      longitude : franchise.direction.loc[0],
      latitude : franchise.direction.loc[1],
      title : franchise.name,
      subtitle : franchise.direction.address,
      image : "testing_pin.png",
      animate : false,
      draggable : false
  });                 
  $.mapView.addAnnotation(annot);
  </code></pre>
