TextShape.visual_bounding_rect was not taking the text rotation into
account. I manually tested drawing the new bounding box on top of the
text for various rotations & anchor settings. For example:
<img width="191" alt="image"
src="https://github.com/user-attachments/assets/56528fc7-7e7d-45af-b92a-c1cd307ff205"
/>
The unit test I added will fail without this patch, but perhaps doesn't
add much value.
