They still maintain an orthogonal coordinate system (I am not clear if
what you want to do does).
They modify the coordinate system, but with data provided by the
G-code, not external data.
The R value is passed through from the G-code interpreter to the
motion system (I think). This also probably explains why only one
rotation is available.
