As indicated in https://github.com/immersive-web/webxr/pull/342
The enums and some of the attributes involved in the WebXR input system were changed recently, and Chrome's implementation should be updated to match.
Renames:
XRPointerOrigin -> XRTargetRayMode
"head" -> "gazing"
"hand" -> "pointing"
"screen" -> "tapping"
XRInputSource.pointerOrigin -> XRInputSource.targetRayMode
XRInputPose.pointerMatrix -> XRInputPose.targetRayMatrix*
*targetRayMatrix may soon be replaced with targetRay, depending on the outcome of https://github.com/immersive-web/webxr/pull/357
