It would seem that this PR should be merged, assuming this is the intent of the pixel size factor. However, any user code will now generate with smaller dots than previously, as previously it acted as though pixelSizeFactor was 1, and the default is 0.8. Test hashes will need to be updated.

Perhaps the default should be set to 1.0 going forward, to match the previous version's default behavior (??)
