Code Review
This pull request addresses a rendering artifact issue with superellipses in Impeller by ensuring the device buffer is flushed after vertex data is written. The fix in RoundSuperellipseGeometry is accompanied by a new unit test that verifies this flushing behavior. The changes are logical and the fix is well-contained. I have one suggestion to improve the test implementation's adherence to the project's C++ style guide.
