* chore(dragging): Rename core/interfaces/i_draggable.ts Rename core/interfaces/i_draggable.ts to core/interfaces/i_draggable.old.ts to make room for new IDraggable. Do not rename actual interface as it's not yet clear that it will be necessary for both to coexist as imports in the same file. * feat(dragging): Introduce new IDraggable interface * feat(dragging): Introduce new IDragger interface --------- Co-authored-by: Beka Westberg <bwestberg@google.com>
