    Render *string* with *font*.  For each character in *string*, yield a
    (glyph-index, x-position) pair.  When such a pair is yielded, the font's
    glyph is set to the corresponding character.

    Parameters
    ----------
    string : str
        The string to be rendered.
    font : FT2Font
        The font.
    kern_mode : int
        A FreeType kerning mode.

    Yields
    ------
    glyph_index : int
    x_position : float
