DESCRIPTION

       d.northarrow displays a north arrow symbol the graphics monitor at the given screen  coordinates.  If  no
       coordinates  are  given  it will draw the north arrow in the bottom right of the display. It can draw the
       north arrow in a number of styles (see the wiki page for details).

TODO

       Add options to use an arbitrary rotation angle for when grid north and true north diverge, and add a flag
       to calculate that convergence angle and apply the rotation automatically.
