- Constify parameters of struct plotter_table::polygon and struct plotter_table::path

- riscos/save_draw.c(ro_save_draw_plotters): Make it static.
- desktop/save_pdf/pdf_plotters.c(pdf_plot_path): fix broken implementation (coordinates path were wrong, no clip/text mode update, transformation matrix was overwritten); only update fill and/or 
stroke color when fill and/or stroke is done.
  (pdf_begin): disable compression when PDF_DEBUG is set
