           Summary: spatial coords should just be in metres

"The units used in the coordinate system are not defined, and do not need to be
because the effects calculated with these coordinates are independent/invariant
of any particular units such as meters or feet."

This is true as far as the subsequent example goes, but is in conflict with the
doppler algorithm, which compares velocities against
AudioListener.speedOfSound, which is explicitly in metres per second.

I suggest the quoted sentence about unit independence just be removed, and that
the spacial fields be clarified to always use metres for length.
