[R-sig-Geo] spplot, polygons, and line density fill

[Matthew Landis]

Hello again R-sig-geo-ers,

Does anyone know how to convince spplot to create a figure like 
http://r-spatial.sourceforge.net/gallery/#fig15.R

I would like to overlay some polygons onto a raster, and I need to do it 
with spplot for the lattice functionality.  I've looked at the help and 
the function code for sp.polygon and grid.polygon, as well as searched a 
bit on Google, but I'm not finding anything promising, but then, I'm not 
that familiar with grid graphics.

Since we're talking about R, I have a hard to time believing the answer 
is "it's not possible".
