I added a test to ensure that certain image operations are invariant over the subpixel precision of an image. This property is important to make APIs behave consistently, especially for
DynamicImagewhich abstracts over different precisions.I only test a few operations for now. 3 operations have their tests ignored, because they are currently not precision invariant. Relevant issues/PRs are mentioned.
