        This class behaves identical to PyChan's Font class except in
        initialization. Ratherthan take a name and a get object, this class
        takes a fontdef and settings object as explained below. This class is
        necessary because the original Font class was too restrictive on how it
        accepted objects

        @param fontdef: defines the font's name, size, type, and optionally 
                        row spacing as well as glyph spacing.
        @type fontdef: dictionary
        
        @param settings: settings object used to dynamically determine the
                         font's source location
        @type settings: parpg.settings.Settings object
