Use case

The paints matcher is missing the ability to test RSuperellipse drawing. I think it is crucial to allow users to test the rounded superellipse drawing after the recent drawRSuperellipse introduction.

flutter/engine/src/flutter/lib/ui/painting.dart

Lines 6022 to 6027 in bb81a93

/// Draws a rounded superellipse with the given [Paint]. The shape is filled,
/// and the value of the [Paint.style] is ignored for this call.
///
/// ![](https://flutter.github.io/assets-for-api-docs/assets/dart-ui/canvas_rsuperellipse.png#gh-light-mode-only)
/// ![](https://flutter.github.io/assets-for-api-docs/assets/dart-ui/canvas_rsuperellipse.png#gh-dark-mode-only)
void drawRSuperellipse(RSuperellipse rse, Paint paint);

Proposal

Add the ability to test rounded superellipse drawing.
