[R-sig-Geo] axes when plotting polys

[Roger Bivand]

Stéphane, Christophe,

I've submitted maptools_0.3-8.tar.gz to CRAN, if it is accepted, it should 
show up soon. I've moved the ... to the plot function setting the plotting 
region, removed ... from the polygon() call, but added the specifically 
polygon() arguments to the plot.polylist() method, which now does do 
shading with density and angle properly - the clipping argument is also 
passed to polygon(). Please let me know if this helps (once it shows up).
