Define the region fill mode.
dev_set_draw defines the region fill mode. If DrawMode is set to 'fill', output regions are filled, if set to 'margin', only contours are displayed. It is used by region output like dev_display, disp_region, disp_circle, disp_rectangle1, disp_rectangle2, disp_arrow, etc. If the mode is 'margin', the contour can be affected by dev_set_line_width, set_line_approx and set_line_style.
If dev_set_draw should be used for exported Code (C++), please note the description of set_draw due to the different semantics in C++.
