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.
