  UIxMailPartViewer
  
  This class is the superclass for MIME content viewers.
  
  Since part-viewers can be reused for multiple parts, you need to be careful
  in subclass to properly reset your specific state by overriding
    - resetPathCaches

  The part viewers have access to the rendering state using the
    
    [[self context] mailRenderingContext]
    
  object. This class provides several convenience methods to access mailpart
  content.
