Returns which of the sixteen compass directions is associated with the specified angle
theta. <em>Note:</em> that the angle supplied is assumed to increase clockwise around the
origin (which screen angles do) rather than counter-clockwise around the origin (which
cartesian angles do) and <code>NORTH</code> is considered to point toward the top of the
screen.
