do_ellipse - Calculates all the points in an ellipse. Allegro game programming library.

       Calculates  all  the points in an ellipse around point (x, y) with radius rx and ry, calling the supplied
       function for each one. This will be passed a copy of the bmp parameter, the x and y position, and a  copy
       of the d parameter, so it is suitable for use with putpixel(). Example:

          void draw_explosion_ring(BITMAP *bmp, int x, int y, int d)
          {
             ...
          }

             do_ellipse(screen, SCREEN_W/2, SCREEN_H/2,
                       SCREEN_H/16, SCREEN_H/32, flame_color,
                       draw_explosion_ring);
