 * A simple theme provider.

 * that manipulates the font size by setting the execution's attribute
 * directly. Thus, it cannot be cached by the client.
 * On the other hand, {@link CacheableThemeProvider} is another example
 * that manipulates the URI for different font size such that
 * the client can cache the result.
