Definition of a contour output pattern.
set_line_style defines the output pattern of region contours. The information is used by prodedures like disp_region, disp_line, disp_polygon etc. The current value can be queried with get_line_style. Style contains up to five pairs of values. The first value is the length of the visible contour part, the second is the length of the invisible part. The value pairs are used cyclical for contour output.
set_line_style does an implicit polygon approximation (see set_line_approx(::3:)). It is only possible to enlarge it with set_line_approx.

stroke line set_line_style(::[20,7]:). point-stroke line set_line_style(::[20,7,3,7]:). passing line (standard) set_line_style(::[]:).
set_line_style returns TRUE, if the parameter is correct and a window is active. Otherwise an exception is raised.
