[R] Unsightly lines from x*y grid in levelplot with Postscript

When I generate levelplot figures with Postscript, the lines from
the underlying grid (i.e., the x and y in z ~ x* y)
show up as faint white lines in the output.  If I have a dense grid,
the lines wash out the contour colors.  I can avoid the problem if
I use png instead, but that brings up other problems.  Any
ideas for how I can get Postscript to not show those lines around
the cells?
