(From update of attachment 5406)
Maybe there should be a FIXME in WebHTMLView where it creates the NSImage
saying that it would be better to delay the actual NSImage instantiation? It
seems that in an overwhelming majority of cases, the WebElementImageKey isn't
used.

Another option, instead of using a proxy or an NSImage subclass, is to use an
NSMutableDictionary subclass for the result of -[WebHTMLView elementAtPoint:]
that knows how to generate the value of the WebElementImageKey from the
WebCoreElementImageRendererKey.
