I'll chime in here because I know someone is creating arrows
using polygons.  I have found that *any* width along the
edge is a problem for arrows: they must be *only* filled and
not stroked or they look like they point to the wrong point.
(Perhaps 0.3 point unscaled would not be a serious problem
for many uses, but remember there is a join at the tip!)
So: is it possible to fill a polygon without stroking the
edge (or to set the edge with to approximate 0)?

By way of comment: this was a real problem in gnuplot up to
version 3.8.  (I've been meaning to check whether it was
fixed in 4.0.)  The arrows were stroked as well as filled,
and they often looked very wrong.

fwiw,
