ThreeDScene.move_camera() results in NotImplementedError

Commit 62050bbb04a1f8e481972e1db36f2634dfbae425 changes the pass statements of some methods in Mobject() into NotImplementedError .

This causes the move_camera method in a ThreeDScene or SpecialThreeDScene to fail, throwing a NotImplementedError, as it uses the interpolate_color method of Mobject.

from manim import *

class TestScene(SpecialThreeDScene):
    def construct(self):
        self.move_camera(
            **self.default_angled_camera_position,
            run_time=1,
        )

The snippet above triggers the NotImplementedError in the interpolate_color method of Mobject()

This could be fixed by reverting the NotImplementedError of the interpolate_color method back into the pass statement that it originally was.

I think it would also prove fruitful if the methods become_partial and pointwise_become_partial also just had pass statements as they could also result in another method somewhere else not working properly.

Yes, become_partial is really useless because its function may be the same as pointwise_become_partial, and the latter is implemented by subclass.

Oh, I see what you mean. That’s a better way.

Also, this is slightly unrelated, but I found that the method become_partial is not mentioned anywhere in the code other than as its definition in Mobject. Should it be removed outright?
