  Method: getCanvasStyle
  
  Returns the specified canvas style data value property. This is useful for
  querying special/reserved <Graph.Node> canvas style data properties (i.e.
  dollar prefixed properties that match with $canvas-<name of canvas style>).
  
  Parameters:
  
  prop  - (string) The name of the property. The dollar sign is not needed. For
  example *getCanvasStyle(shadowBlur)* will return *data[$canvas-shadowBlur]*.
  type  - (string) The type of the data property queried. Default's *current*. You can access *start* and *end*
  data properties also.
  
  Example:
  (start code js)
  node.getCanvasStyle('shadowBlur');
  (end code)
