public interface FontConvertible

This is an interface which describes the feature to be convertible into a font.

A font specification can either be a font stored in a font register or one of the fonts used for math typesetting.

The formal description is the following:

    ⟨font⟩
        →  ⟨loaded font⟩
         |   \textfont ⟨8-bit number⟩
         |   \scriptfont ⟨8-bit number⟩
         |   \scriptscriptfont ⟨8-bit number⟩
         |   \font
