Python < 3.10 - TypeError: 'staticmethod' object is not callable

[jeertmans]

Describe the bug

It looks like ManimGL is no longer compatible with Python < 3.10, as, prior to this Python version, @staticmethod were not regular callable (hence, using them as a wrapper didn't work).

See here https://stackoverflow.com/a/76237739.

Code:

from manimlib import *

Wrong display or Error traceback:

manim_slides/slide/manimlib.py:4: in <module>
    from manimlib import Scene, ThreeDCamera
.venv/lib/python3.9/site-packages/manimlib/__init__.py:12: in <module>
    from manimlib.window import *
.venv/lib/python3.9/site-packages/manimlib/window.py:20: in <module>
    class Window(PygletWindow):

    def on_mouse_motion(self, x: int, y: int, dx: int, dy: int) -> None:
E   TypeError: 'staticmethod' object is not callable

Additional context

See:

Static methods (@staticmethod) and class methods (@classmethod) now inherit the method attributes (module, name, qualname, doc, annotations) and have a new wrapped attribute. Moreover, static methods are now callable as regular functions. (Contributed by Victor Stinner in bpo-43682.)
