Re: [w3c/pointerlock] Provide more information about movementX/Y for unadjusted movements (Issue #98)

kvnloo left a comment (w3c/pointerlock#98)

For games, converting raw counts into screen coordinates loses one useful property: stable physical mouse sensitivity.

Native engines commonly reason in device counts and let the game apply sensitivity independently of OS pointer acceleration/display scaling.

It may be worth exposing enough metadata to distinguish raw device counts from screen-space movement rather than forcing `unadjustedMovement` into the adjusted coordinate model.

A cross-browser experiment with identical hardware at multiple OS scaling settings would make the tradeoff measurable.
