Log Message:
-----------
Implement simple test of plfill for the case where the polygon is just
outside the window to demonstrate a current bug (no fill) for this situation.
If you reverse the sign of eps so the polygon is just inside the window,
then the fill occurs properly.  If one side of the polygon is just
inside the window (replace xmin = xmin - eps with xmin = xmin +eps), then
the fill occurs in that case as well.
