Internally, it's a visual effect, which means we have to manually activate the cross-section mode
with 'v.set_cross_section(True). This activates the cross-section with default values for the plane.
You can change the plane description with v.cross_section(origin, normal), where 'origin' is a point
on the plane, and 'normal' is the normal of the plane.
To deactivate the cross-section, just use 'v.set_cross_section(False)'.
