Description

To support visual regression testing, I am requesting a new feature.

ImageSharp already contains Image comparison in the Test namespace located here:
https://github.com/SixLabors/ImageSharp/tree/master/tests/ImageSharp.Tests/TestUtilities/ImageComparison

These methods call internal methods in the main ImageSharp library and so I'm currently resorting to reflection to do this.

Could these be moved to a separate NuGet library for public consumption?

Research direction

Start in tests/ImageSharp.Tests/TestUtilities/ImageComparison, where the existing image comparison utilities are located, and review the internal ImageSharp methods they call. Determine the package boundary and public API needed for visual regression testing. Done means the utilities are available through a separate NuGet library for public consumption without reflection.
