 When `OverlayManager#setMyLocationEnabled(true)` is called, an icon is displayed to allow centering the map on the user's current location upon click. While enabled, the `OverlayManager` will continue to update the latest location but will only update the map when the button is clicked. When `OverlayManager#setMyLocationEnabled(false)` is called, this icon is hidden and location updates are stopped.
