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.
Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
Given a WebKitPoint specified in a particular DOM Node's coordinate system, the Window method webkitConvertPointFromNodeToPage() returns a Point which specifies the same position in the page's coordinate system. This method is non-standard and should not be used.
Warning: Please review the Browser compatibility section before using this method, as it's not widely supported (nor is the WebKitPoint object it uses).
