Sticky panning means that the map panning is restricted, user is able to freely pan the map, but zooming and rotating gestures can't be performed at the same time. User is still able to switch between zooming and rotating the map but it takes a bit more effort compared to FREE panning.
Final sticky panning: like sticky panning, but once the gesture type is determined the user is stuck with either zooming or rotating until at least one of the two fingers is lifted.
Free panning means that the map panning is unrestricted, user is able to zoom, rotate and pan the map at the same time without any artificial limits.
