[Rd] Re: polygon border colors

[Denis White]

I think I see in do_polygon() in plot.c that border colors are
not cycled, and that changes in the lines

...
    PROTECT(border = FixupCol(CAR(args), dd->gp.fg));	args = CDR(args);
...
		GPolygon(i-start, x+start, y+start, USER,
			 INTEGER(col)[num%ncol], INTEGER(border)[0], dd);
...
	    GPolygon(nx-start, x+start, y+start, USER,
		     INTEGER(col)[num%ncol], INTEGER(border)[0], dd);
...

following the pattern for "col" might make cycling possible.

Is this a change that I should try locally, or could this be
considered for the standard version?

thanks,

Denis

Subject: polygon border colors

Simple question: is it true that 

  polygon (x, y, col=vec, border=vec, ...)

will cycle through the vec colors for fills but not for
the border colors when sending multiple polygons?

thanks,
