Description

Description of the proposed feature

The feature I want to propose is a zoom deactivation system It would look like this.

from manim import *
class Basic(ZoomedScene):
    def construct(self):
             self.activate_zooming(animate=False)

             self.deactivate_zooming(animate=False)

I would like to do this because we can activated zooming but not deactivate it.

How can the new feature be used?

In cases where you would like to zoom in for a little bit but then remove the zoom.

Research direction
Examine the ZoomedScene class in manim/scene/scene.py to understand the activate zooming implementation. Implement a deactivate zooming method that reverses the zoom behavior. Ensure the animate parameter is handled consistently. Look at existing tests for zooming (e.g., test zoomed scene.py) to add a corresponding test for deactivation.
