%% SPHERE_STEREOGRAPH_DISPLAY_TEST displays stereographic mappings.
%
%  Discussion:
%
%    The first test displays a calculation in which points on the
%    sphere are mapped to points on the plane.
%
%    The second displays a case in which points on a circle in the
%    plane are mapped to points on the sphere.
