Description
Consider the following scene:
```python
class Test(Scene):
def construct(self):
test = Tex("M")
test.set_stroke(color = RED, width = 8)
self.add(test)
```
This is the result with the cairo renderer:
I would expect those devil horns not to be there. Interestingly, while the problem seems to be there in the opengl renderer as well, it's not nearly as pronounced.

Research direction
Start with the provided scene using Tex("M") and set_stroke(width=8), rendering it with both the cairo and opengl renderers to reproduce the difference. Trace the stroke handling for Tex objects from this entry point. Done means the cairo result no longer shows the unintended devil horns and remains consistent with the opengl result.
