It is not an error if the border skin does not implement IBorder. 
  In this case, however, the container using the skin cannot determine 
  the border metrics of the border. 
  Therefore, the container places content starting at its top-left edge 
  (adjusted for padding, if any). 
  For the HaloBorder class, the borderThickness style 
  usually determines the value of the borderMetrics style. 
  For graphical skin classes, Flex examines the scale9Grid
  property to determine the value of the borderMetrics style.
