Definition of the region output shape.
set_shape defines the shape for region output. It is only valid for the active window. The output shape is used by disp_region. The available shapes can be queried with query_shape.
Available modes:
'original'
The shape is displayed unchanged. Nevertheless
modifications via parameters like set_line_width or
set_line_approx can take place. This is also true for
all other modes.
'outer_circle'
Each region is displayed by the smallest surrounding
circle. (See smallest_circle.)
'inner_circle'
Each region is displayed by the largest included
circle. (See inner_circle.)
'ellipse'
Each region is displayed by an ellipse with the same
moments and orientation (See elliptic_axis.)
'rectangle1'
Each region is displayed by the smallest surrounding
rectangle parallel to the coordinate axes. (See
smallest_rectangle1.)
'rectangle2'
Each region is displayed by the smallest surrounding
rectangle. (See smallest_rectangle2.)
'convex'
Each region is displayed by its convex hull (See
convex.)
'icon'
Each region is displayed by the icon set with
'set_icon' in the center of gravity.
Caution is advised for greyvalue output procedures with output parameter settings that use region output, e.g. disp_image with set_paint(::'histogram':) and set_shape(::'convex':). In that case the convex hull of the greyvalue histogram is displayed.

set_shape returns TRUE, if the parameter is correct and a window is active. Otherwise an exception is raised.
