 *  the richness of a TextFlow, you should consider using
 *  Label instead.</p>
 *
 *  <p>At compile time, you can simply put TLF markup tags inside
 *  the RichText tag, as in
 *  <pre>
 *  &lt;s:RichText&gt;Hello &lt;s:span fontWeight="bold"&gt;World!&lt;/s:span&gt;&lt;/s:RichText&gt;
 *  </pre>

 *  right-to-left (RTL) text such as Arabic, and bidirectional text
 *  such as a French phrase inside of an Arabic one.
 *  If the predominant text direction is right-to-left,
 *  set the <code>direction</code> style to <code>rtl</code>.
 *  The <code>textAlign</code> style defaults to <code>"start"</code>,
 *  which makes the text left-aligned when <code>direction</code>
 *  is <code>ltr</code> and right-aligned when <code>direction</code>
 *  is <code>rtl</code>.
 *  To get the opposite alignment,
 *  set <code>textAlign</code> to <code>end</code>.</p>
 *
 *  <p>RichText uses TLF's StringTextFlowFactory and TextFlowTextLineFactory
 *  classes to create one or more TextLine objects to statically display
 *  its text.
 *  For performance, its TextLines do not contain information
 *  about individual glyphs; for more info, see the TextLineValidity class.</p>
