[X3D-Ecosystem] OSC mocap support in X3D Browsers

[John Carlson]

Here’s a sample VMC implementation in C#, but I don’t know how it
interfaces with hardware yet:
https://github.com/sh-akira/VirtualMotionCaptureProtocol/tree/master/sample/VRM1

It also focuses on bones, and perhaps X3D wants to focus on joint
rotations, which may require IK and calibration, potentially provided by
hardware.

Bone position and rotation are provided.
