The rich text can contain clickable hyperlinks and inline graphics that are either embedded or loaded from URLs. RichEditableText does not have scrollbars, but it implements 
the IViewport interface for programmatic scrolling so that it can be controlled by a Scroller, which does provide scrollbars. It also supports vertical scrolling with the mouse wheel." />
