Define the line width for region contour output.
set_line_width defines the line width (in pixel) in which a region contour is displayed (e.g. with disp_region, disp_line, disp_polygon, etc.) The procedure get_line_width returns the current value for the window. Some output devices may not allow to change the contour width. If it is possible for the current device, it can be queried with query_line_width.
The line width is important if the output mode was set to 'margin' (see set_draw). If the line width is greater than one, regions may not always be displayed correctly.

set_line_width returns 2 (H_MSG_TRUE) if the parameter is correct and the window is valid. Otherwise an exception handling is raised.
set_line_width is reentrant and processed without parallelization.
