    themingengine: Remove hack to draw backgrounds instead of checks
    
    This was a hack we added in early 3.x to allow themes to customize their
    checkmarks.
    Now that we want to properly support real backgrounds everywhere,
    supporting this feature would cause double draws of backgrounds.
