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?
