I've done that now.

I've done that now.

 * The same as D_symbol(), but it uses a primary and secondary color
 * instead of line and fill color. The primary color is used to draw
 * stroke lines (STRINGs) and as the fill color for polygons. The
 * secondary color is used for polygon outlines.
TODO: merge duplicate D_symbol() code into common lib fns in symbol.c

don't know, can you reproduce it with a spearfish map?
make distclean? ;)

In the past segfaults had arisen from untested combinations of
color=none and fcolor=none leading to uninit'd variables, but I think
I've caught all those. One thing I haven't tested is using with
rgb_column, but I haven't touched that part of d.vect so I think it'll
still be ok.
