RootLayoutPanel is a container that takes up all the visible area and
always resizes to cover the whole viewport.
Other than that, it's a LayoutPanel, so it wraps all its children
within a div to be able to accurately manage their position and size
in all supported browsers. And it creates an additional, hidden, div
(two in the case of IE6) as a way to measure EMs and EXs in pixels.
So, yes, those divs are necessary.
But RootLayoutPanel and RootPanel are not interchangeable, they have
distinct purposes.
