Resolution Note (fix version 2019.3):
Touch.Radius hadn't been implemented since many Windows touch devices doen't seem to support it.
The Surface line of devices does support this API, and so it will now return non-zero values for both the Editor and Standalone player when running on a 'Surface'. However, for other touch-enabled devices, it may still return 0.
