Background

As part of the PR05 grant project, development of visual-regression-engine has been completed and the npm package published.
This engine provides the core functionality for comparing images and detecting visual regressions.

Phase 2 is now ready to begin: implementing a comprehensive visual testing framework for the Processing Core library.
This will help us catch rendering bugs and ensure consistent visual output across all supported platforms and future versions.

Hence before implementing, I was hoping to get a thorough discussion of possible implementations and how will they benefit the contributors.
