I’ve implemented a preliminary cut at head faking, and hooked up the “look at” primitive!

It’s not content based yet (it procedurally turns just the head, up to a certain amount), nor have I finished adjusting it, but it basically works!

The ideal content based approach (which we can move to if the current implementation doesn’t look good enough) could use an artist-supplied animation of the head (and possibly other bones like the shoulders) turning from the left most extreme to the right most extreme, so the artist could control the extremes and the timing (slowing down the turn as it nears the extremes), but right now those parameters are adjustable constants wired into the code. …
