After giving this some thought this morning in the shower,
I'm almost certain that if I were writing a cgPolarContour
program, I would not do it this way. I think I would
actually put the contour plot on a Polar Stereo map
projection. That way, the polar plot would look, uh,
polar, and you could use your map annotation programs
(e.g., cgMap_Grid) to annotate the plots with circles
and radial lines, which is how a polar plot *should*
be labeled, I think.

Cheers,

David
