       _X_s_h_o_w_t_r_a_c_e takes a RADIANCE octree and a picture file and  displays  it
       on  an X11 window server using _x_i_m_a_g_e_(_1_)_.  The picture should have been
       created from a previous _r_p_i_c_t_(_1_) or _r_v_u_(_1_) calculation using the  given
       octree.   Once the image is displayed, the user can use the 't' command
       of _x_i_m_a_g_e to select points on  the  image  to  display  the  ray  tree.
       _R_t_r_a_c_e  then produces a ray tree, which _x_s_h_o_w_t_r_a_c_e will display (in red
       on a color screen).  The _-_s option slows the display of each ray traced
       to make it easier to follow the process.

       If  the pointer is moved between the time 't' is pressed and _x_s_h_o_w_t_r_a_c_e
       starts drawing rays, the rays will be displaced.
