[pointerevents] Limit the precision of floating point event fields (#517)

jyasskin has just created a new issue for https://github.com/w3c/pointerevents:

== Limit the precision of floating point event fields ==
There's a history of factory calibration information being used to fingerprint individual devices. I haven't investigated whether this is possible on common pointing devices, but as a precaution, would it make sense to establish a normative limit on the precision of the fields in pointer events, similar to what was done for deviceorientation and accelerometer? See https://github.com/w3c/deviceorientation/pull/86, which limited angle measurements to 0.1 degrees.
