Actually I have implemented a new "CellFill" method that fills the
cells of a grid individually.
Unlike the raster mode it draws the actually shape of a cell as
projected rather than giving a pixelated
approximation, and allows transparency for unfilled areas. It also has
options for drawing lines around the cell boundaries. It will
hopefully be available in the next version of NCL.
I attached some example gifs to a note earlier today but it has been
held back apparently because of limitations on the size of messages
posted to ncl-talk.
