title: IKImageBrowserView inside padding
body: <p>I'm customizing an <code>IKImageBrowserView</code> and I would like to change the space between cells.</p>
  
  <p>I'm using this method <code>[_imageBrowser setIntercellSpacing:NSMakeSize(0, 0)]</code> to set the spacing between cells to 0 pixels and it works.</p>
  
  <p>But I notice an inside padding of 10 pixels in the IKImageBrowserView : </p>

  <p>Any Idea?</p>
