A plot is accepted when it matches any of several reference images, so a matplotlib upgrade that changes the rendering only needs an extra reference image (<stem>.<tag>.png) rather than replacing the existing one.
Rendered with the matplotlib shipped in DIRACOS for Python 3.14, so the plot comparison tests pass on both the previous and the new matplotlib.

No need for release notes as this is just a test suite compatibility fix.
I also add support for comparing multiple reference images to make the transition easier.
