Update Coordinates - Always Redraw

I'm attempting to track the coordinates of a function, but I don't seem to be able to get always_redraw as it is not defined to work. Is this a new feature?

```
def construct(self):
self.wait()
self.setup_axes()
graph = self.get_graph(lambda x: x**3, x_min=-5, x_max=5)

initial_x = -5
final_x = 5
track = ValueTracker(initial_x)

coor = self.coords_to_point
dot = track.get_value
func = graph.underlying_function
moving_dot = always_redraw(lambda: Dot(coor(dot(), func(dot()))))

self.add(graph, moving_dot)
self.play(track.set_value, final_x, run_time=5)
self.wait()
```

Look for the definition of 'always_redraw' in the manim codebase, likely in a module like mobject/updaters.py or scene/scene.py. Check if it's imported or if there's an alternative method like 'always_redraw' as a decorator or function. Run the provided code snippet to see the error and verify the fix by ensuring the dot updates with the ValueTracker.
