Window.convertPointFromNodeToPage()
Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
 Given a WebKitPoint specified in a particular DOM Node's coordinate system, the Window method convertPointFromNodeToPage() returns a Point which specifies the same position in the page's coordinate system. This method is non-standard and should not be used.
