So they are both client-side renderings. In the first case, the render
should extend RendererBase, then directly spit out Dojo-based widget for
client-side rendering (using the utilites classes); And in the later
case, it is just talking about page authour's own JavaScript that
depends on Woodstock's theme and dojo libraries, etc., is my
understanding right?
