OpenGL - Cairo discrepancy: Can't use more than one argument for shift

Nobody has claimed this yet.

## Description of bug / unexpected behavior

The shift function of all Mobjects accepts an arbitrary number of summed-together movement vectors. On OpenGL however, more than one argument gives a strange error.

## Expected behavior

The multiple arguments should either be an error on both renderers or work on both renderers.

## How to reproduce the issue

Code for reproducing the problem

```py
class Example(Scene):
def construct(self):
# any mobject works
text = Text('blah')
text.shift(UP, LEFT)
```

## Logs
Terminal output

TypeError: OpenGLMobject.shift() takes 2 positional arguments but 3 were given
```

Start by running the provided Example scene with Text('blah') and text.shift(UP, LEFT) using the OpenGL renderer, then compare the shift entry point shown in the traceback, OpenGLMobject.shift, with the Cairo behavior. Done means multiple shift vectors either work consistently in both renderers or are rejected consistently, without the reported TypeError.
