* {@link DefaultFont} implementation that maps to a value in the current theme.

* This is typically useful to make sure that a font always defaults to the same value as another theme property.
* Care should be exercised when using this class, however: it doesn't check for infinite recursion, meaning it's
* entirely possible to freeze muCommander by linking a font to itself as a default.
