Displays crosses in a window.
disp_cross displays one or several crosses in the output window. A cross is described by the coordinates of the center point (Row,Column), the length of its bars Size and the orientation Angle. The procedures used to control the display of regions (e.g. set_color, set_gray, set_draw, set_line_width) can also be used with crosses. Several crosses can be displayed with one call by using tuple parameters. For the use of colors with several crosses, see set_color.
