The UYLTextStyleViewController shows the standard way to listen for
13+
and respond to changes to the users preferred text size using the
14+
built-in UIFont Text Styles.

20+
The UYLScaledTextStyleViewController extends the basic approach by
21+
showing how to scale the preferred fonts using a UIFontDescriptor.
22+
A convenience method to return the scaled font is added as a
23+
category of UIFont for this purpose.
