-/**
- * Make an element draggable in the given [orientation].
- *
- * The main difference with [multiPointerDraggable] and
- * [androidx.compose.foundation.gestures.draggable] is that [onDragStarted] also receives the number
- * of pointers that are down when the drag is started. If you don't need this information, you
- * should use `draggable` instead.
- *
- * Note that the current implementation is trivial: we wait for the touch slope on the *first* down
- * pointer, then we count the number of distinct pointers that are down right before calling
- * [onDragStarted]. This means that the drag won't start when a first pointer is down (but not
- * dragged) and a second pointer is down and dragged. This is an implementation detail that might
- * change in the future.
