function circle_sector_print_2d ( r, center, theta1, theta2 )

%*****************************************************************************80
%
%% circle_sector_print_2d() prints a circular sector in 2D.
%
%  Discussion:
%
%    A circular sector is formed by a circular arc, and the two straight line
%    segments that join its ends to the center of the circle.
%
%    A circular sector is defined by
%
%      ( X - CENTER(1) )^2 + ( Y - CENTER(2) )^2 = R^2
%
%    and
%
%      Theta1 <= Theta <= Theta2
