- 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 svn path=/trunk/netsurf/; revision=6361
