title: Eliminating the border of a grouped table cell
body: <p>I have a grouped table view; the table's background is a custom image.  In one type of cell, I have just an image, and it doesn't fill up the entire cell width, and it's centered in the cell.</p>
  
  <p>I've set that's cell's background to UIColor -clearColor, so that the table's background view shows through, but the cell is still drawing the light gray border (the rounded rectangle outline).  I need it to NOT do that!</p>
  
  <p>I've tried setting the cell's contentView's background to clear as well, and I've tried setting the table separator style to none, but still the outline draws.</p>
  
  <p>Is it possible to prevent that from drawing?</p>
