/**
 * ### `useControlsContext`
 *
 * Internal registry of the controls instances mounted within the current
 * `<Canvas>`. Each controls component (`<OrbitControls>`,
 * `<TrackballControls>`, `<CameraControls>`, `<TransformControls>`) registers
 * itself here on mount and clears its entry on unmount.
 *
 * It powers two things:
 * - `<TransformControls>` reads the camera controls to enable/disable them
 *   while a transform gizmo is being dragged.
 * - The public `useCameraControls`, `useOrbitControls`, `useTrackballControls`
 *   and `useTransformControls` hooks expose the registered instance to user
 *   code.
