Improved head offset accuracy by a lot and some other small changes.
The data for analysing head pos: https://www.geogebra.org/classic/uaphpn2k

Wasn't aware that the camera zoom changed, which I use to get higher pixel density, but that's fixed now.

Updated 3d Projection Demo.

Changed the code for roll to:
math.atan(math.sin(tiltSensor.left * tau), math.sin(tiltSensor.up * tau))

Instead of:
math.asin(math.sin(tiltSensor.left*tau)/math.sin((.25-tiltSensor.forward)*tau)
if tiltSensor.up < 0 then ang.y = math.pi-ang.y end


Yields the same accurate output, but the former is a lot nicer.

Uploaded 3d Projection Demo to the Workshop.
