The simplest way to do is is exactly as done, in that demo. It uses the
"backgroundColor" property of widgets, which can be used with any widget.
The only thing you really need to be careful of is that many widgets use
decorators that completely fill the widget, so the background is covered.
For drawing simple colored rectangles, unless you have a large number of
them, the method is simple and reasonably efficient, using the DOM's "div"
elements.
