Remarks:
The EffectControlPath class provides access to all effects that are attached to a path. A control path is a curve that determines the shape of an Artistic Media stroke. When you edit an Artistic Media stroke, you edit the control path of the stroke. The stroke itself is a closed path following the control path. When you shape the control path, the stroke shifts according to how you edit the control path. If you want to edit the closed path directly, you must first separate it from the control path.
