Displays regions in a window.

disp_region displays the regions in DispRegions in the output window. The parameters for output can be set with the procedures set_color, set_gray, set_draw, set_line_width, etc.

The color(s) for the display of the regions are determined with set_color, set_rgb, set_gray or set_colored. If more than one region is displayed and more than one color is set, the colors are assigned in a cyclic way to the regions.

The form of the region for output can be modified by set_paint (e.g. encompassing circle, convex hull). The command set_draw determines if the region is filled or only the boundary is drawn. If only the boundary is drawn, the thickness of the boundary will be determined by set_line_width and the style by set_line_style.

/* Output with 12 colors: */
set_colored(WindowHandle,12) 
disp_region(SomeSegments,WindowHandle).

/* Symbolic representation: */
set_draw(WindowHandle,'margin') 
set_color(WindowHandle,'red') 
set_shape(WindowHandle,'ellipse') 
disp_region(SomeSegmentsWindowHandle).

/* Representation of a margin with pattern: */
set_draw(WindowHandle,'margin') 
set_color(WindowHandle,'blue') 
set_line_style(WindowHandle,[12,3]) 
disp_region(Segments,WindowHandle).

disp_region returns 2 (H_MSG_TRUE).

disp_region is reentrant, local, and processed without parallelization.
