~~stretch~~ is used to scale a ~~Mobject~~ about the center of the ~~Mobject~~ by the specified scale_factor parameter, scale_factor, according to the specified parameters.

def scale_about_point(self, scale_factor, point)

~~stretch~~ is used to scale a ~~Mobject~~ about the specified point parameter, point, by the specified scale_factor parameter, scale_factor, according to the specified parameters.

def stretch(self, factor, dim, **kwargs)

~~stretch~~ is used to stretch a ~~Mobject~~ about the point parameter, point by the specified factor parameter, factor, with respect to the specified dim parameter, dim, according to the specified parameters.

def stretch_about_point(self, factor, dim, point)

~~stretch_about_point~~ is used to stretch a ~~Mobject~~ about the specified point parameter, point, by the specified factor parameter, factor, with respect to the specified dim parameter, dim, according to the specified parameters.

def stretch_in_place(self, factor, dim)
