◆ setupRelocateDrag()

void setupRelocateDrag ( )

Terminal builder operation: establish the infrastructure for the already defined participants to be involved into a dragging gesture, for the purpose of relocating the subject.

Remarks: Typical example would be dragging a Clip within the timeline. This invocation would then create a suitable InteractionState subclass and use the previously given Subject to hook up signal bindings for the trigger condition to start forming the "drag a clip" gesture.
