Discussion
By default, the action message is changeFont:. This action method causes the receiver to send its action message up the responder chain.
When a responder replies by providing a font to convert in a convert(_:) message, the receiver converts the font by sending a convert(_:) message to the Font panel. The panel in turn may send convert(_:toFamily:), convert(_:toHaveTrait:), and other specific conversion methods to make its change.
