Interface DragOptions

Coalesce moves: each DragSession.move only remembers its pose, and the latest one is applied once at the next Scene.commitFrame (or DragSession.end). For pointer events at 120–250 Hz: without it, every move recomputes the eager fields. Until the frame, Scene.placement and Scene.matrix4 show the last applied pose. WorkerScene drags always coalesce. Defaults to false.
