+ * Detects a drag gesture **without** trying to filter out any misclicks. This is useful in menus
+ * where items are dragged around, where the usual misclick guardrails would cause unexpected lags
+ * or strange behaviors when dragging stuff around quickly. For other use cases, use
+ * [androidx.compose.foundation.gestures.detectDragGestures] or
+ * [androidx.compose.foundation.gestures.detectDragGesturesAfterLongPress].
+ *
+ * @param beginDragGesture called when the user first touches the screen (down event) with the
+ * pointer position, should return `true` if the receiver wants to handle this gesture, `false`
+ * otherwise.
+ * @param handleDragGestureChange called with the current pointer position, every time the user
+ * moves the finger after [beginDragGesture] has returned `true`.
+ * @param endDragGesture called when the drag gesture finishes after [beginDragGesture] has returned
+ * `true`.
