Updated Code 
//native elem.scrollIntoView() works similar to an #anchor, putting top-left of element at top-left of viewport

//set document scroll position
//optionally, specify a particular window/frame
function setDocumentScrollPosition(top, left, windowFrame)
{
	windowFrame = windowFrame || window;
	var w = new WindowDimensions(windowFrame);
	if(isNaN(top)) top = w.window.scroll.top;
	if(isNaN(left)) left = w.window.scroll.left;
	
	//note: window.pageX/YOffset is read-only; the other two seem to depend on whether the browser is in quirks mode or not
	windowFrame.document.body.scrollLeft = left;
	windowFrame.document.documentElement.scrollLeft = left;
	windowFrame.document.body.scrollTop = top;
	windowFrame.document.documentElement.scrollTop = top;
}

//set element scroll position

{
	elem.scrollLeft = left;
	elem.scrollTop = top;
}
