[R-sig-Geo] graticules for projected data

[Hadley Wickham]

> As you can tell from the final example, I really appreciate the look and feel of ggplot2 and use it for most of my non-map plots. However, I have, maybe wrongly, presumed fortify only works for spatial polygons and lines. I often have a need to map spatial points, pixels or grids and so have stuck with spplot for most of my mapping.

Those are (fairly) easily added - but I don't have any test cases and
no one has asked for them before...
