	//	summary
	//	Scroll the passed node into view, if it is not.

	// don't rely on that node.scrollIntoView works just because the function is there
	// it doesnt work in Konqueror or Opera even though the function is there and probably
	//	not safari either
	// native scrollIntoView() causes FF3's whole window to scroll if there is no scroll bar 
	//	on the immediate parent
	// dont like browser sniffs implementations but sometimes you have to use it
	// #6146: IE scrollIntoView is broken
	// It's not enough just to scroll the menu node into view if
	// node.scrollIntoView hides part of the parent's scrollbar,
	// so just manage the parent scrollbar ourselves
	var parent = node.parentNode;
	var parentBottom = parent.scrollTop + dojo.marginBox(parent).h; //PORT was getBorderBox
	var nodeBottom = node.offsetTop + dojo.marginBox(node).h;
