Send a joint's turn over the network in four bytes without it flipping or drifting

A full body has many joints and each one's rotation is four numbers. Sending them all as they are is far too heavy, and the obvious shrinking either breaks the rotation or makes arms flip when two screens round differently. Here is a packing that keeps joints stable.

Why this works

A turn has a fixed total size, so once three parts are known the fourth follows, and leaving it out costs nothing. Dropping the biggest part keeps the rest small and precise, and flipping the sign gives the same turn only one spelling, so two screens never round differently.

When not to use it

Wrong for a few important joints, such as a camera or a weapon, where full precision is cheap and an error shows up large. Also unneeded when the pose is replayed from a clip: send the clip and the time, not the joints.
