That’s… interesting. So by putting the morph I care about into a ‘fake morph’ that doesn’t even enclose it and rotating that in a TransformationMorph it does pretty much what I need. Really clever and completely not what I’d ever expect.
Has to be a more easily usable approach that we can come up with to do this, surely. What is the purpose of the entire rotationCenter thing if not to make it be the center of any following rotations?
