Summary: plfill fails to fill if the polygon is outside the window

Initial Comment:
The 7th subpage of the first two pages of example 25 are empty when they should be filled (with red).  examples/python/test_fill.py demonstrates the issue in a much simpler way.  For the committed version of that simple test, the plfill polygon boundary is just outside the window and for this case plfill fails to fill.  However, if you move the boundary just inside the window (by reversing sign on eps)  or if you put the xmin boundary just inside the window with the rest of the polygon boundary outside the window, then plfill, fills properly.  (Presumably, that is also the case for the xmax, ymin, and ymax boundaries as well.)
