gnuplot graphics: Fix MarkerFaceColor invalid and MarkerEdgeColor 'none' bugs (bug #47974).

* __gnuplot_draw_axes__.m: If after calling do_linestyle_command() the style
  is empty, use 'points' as a placeholder point-type but leave the data empty.
  (gnuplot_pointtype): Treat '.' point type as having no marker face and
  therefore no color.
