Long Text being cut down

### Describe the bug
In ManimGL v1.6.1 with manimpango v0.4.1, when passing a long string to `Text`, parts outside the screen are cut.

**Code**:
```py
class Textbug(Scene):
def construct(self):
text = "The study of this language does not require a bulky knowledge of numerous parts of mathematics; although some preliminary acquaintance with calculus and algebra is more than welcome."
text_box = Text(text, font="Consolas").scale(0.7)
self.add(text_box)
```

**Wrong display or Error traceback**:


Look at the Text class in manim, likely in manim/mobject/svg/text_mobject.py or similar. The bug is about text rendering and clipping; start by understanding how manimpango renders text and where the clipping occurs. Check the scene's camera or viewport settings. Run the provided example to reproduce the issue, then trace through the rendering pipeline to see where the text gets cut off.
