title: setting UIImageVIew of UITableViewCell as opaque
body: <p>I and profiling using Core Animation and my UIImageView on a UITableViewCellStyleSubtitle is showing as blending (in red) instead of being opaque.</p>
  
  <p>I am setting the image like so:</p>
  
  <pre><code>    // This is just a helper method that loads a .jpg from the disk
      UIImage *img = [Helpers getThumbnailImageIfExists:[obj valueForKey:@"PhotoName"] withManufacturer:self.client.ManufacturerID];
      cell.imageView.image = img;
     [cell.imageView setOpaque:YES];
  </code></pre>
  
  <p>I thought this should do it but it still shows as not being opaque.  I am having the same issues with some UIButtons that I am adding to my contentView</p>
