stop

Stops or pauses the active operation of this control.

This typically involves pausing content playback, animations, or data fetching, and potentially reducing resource consumption. The control should retain its state so it can be resumed by #start().

Calling stop()} on an already stopped control should be a no-op.

If the marquee is currently running (scrolling), this method will interrupt the drawing thread, wait for it to finish, and then set the running state to false. The drawing thread reference is also set to null.
