That doesn't work because it gives the screen position of the top/left 
edge of the browser window, not of the content are the web page is 
rendered into.  So if you have a screen coordinate and you want to 
translate it into page-relative coordinates, this won't do what you 
want: you'll be off by the size of the window decorations and the 
browser chrome.
