We've deprecated this for over 20 years but not been very loud about it.


  Extended drawing commands
    GNU pic does not produce troff escape sequences employing these
    extensions if its -n option is given.

    Df n
        Set the shade of gray used to fill geometric objects to n, which
        must be an integer.  0 corresponds to white and 1000 to black.
        A grayscale ramp spans the two.  A value outside this range uses
        the stroke color as the fill color.  The fill color is opaque.
        Normally the default is black, but some drivers may provide a
        way of changing this.  Df is obsolete since 2002, superseded by
        DFg below.

        The corresponding \D'f' escape sequence should not be used: its
        argument is rounded to an integer multiple of the horizontal
        motion quantum, which can limit the precision of n.


Get louder.  We want the formatter to howl about these as escape sequences and
the output drivers to howl about them as commands.
