“floor level” reference frame for non Unity apps?

In the latest release notes for the Oculus Utilities for Unity 5 it mentions:
Added “floor level” reference frame for apps that need accurate floor height.

How can applications using the Oculus SDK directly get values in the same space? I haven't seen anything in the 1.3.0 SDK documentation that addresses it.

    I believe I recall from watching a presentation at GDC2016 that the Oculus SDK supports retrieving positional data in either a "standing" reference frame, or in a "head-relative" reference frame. One shouldn't be too difficult to derive from the other. You can likely make the assumption that the player's feet are directly below the HMD and subtract the user's inputted height in "standing mode".

    Tangentially related: when you run the 1.3 Oculus setup and it tries to ascertain your standing height I am not completely clear given the wording how this relates if you intend to use the Rift for a purely sitting experience.

    For example if you should be sitting in the setup when it asks you to stand? (as stupid as that sounds!), and the implications this may have for tracking data via the SDK or it's supposed reference floor height?
