Thank you Ian for the clear use case write up (and to Artillery for progress on a great product), Florian Brandon and Glenn for discussion & contributions. As Florian mentioned, we did discuss this use case in 2011 and at that time I attempted to summarize the situation in the pointer lock spec FAQ [1]. Please do read that discussion of the related 3 topics of clipping, motion while clipped, and raw data. One way to move forward on those topics is to prototype functional solutions on Windows, Mac, and Linux and illuminate a practical solution that browsers may adopt. I did an investigation in 2011 and did not find a solution. For clipping only I believe Mac was the only platform I didn't find a solution for. Windows has ClipCursor() and Linux has XGrabPointer(). Once we know we can implement the functionality, we can discuss how to express this in an API.
