I hacked it. There should have been a way for me to do it properly, but I didn't. This is bad for the 0.616-ResearchProject and technically it's wonky for pieces that can "face" different directions (like our knight).

Every other version uses quaternions to rotate and then offset before drawing. For sure 1.14.4 has a similar thing and we should undo this hack, probably on both the production 1.14.4 and the ResearchMilestone branches.
