ARFrame.displayTransform(withViewPortSize: Orientation) documentation unclear (or the method behaves incorrectly)

Number:rdar://33342700 Date Originated:
Status: Resolved:
Product:ARKit Product Version:IOS 11 beta 3
Classification:But Reproducible:
I expected the displayTransform(withViewPortSize: Orientation) method on ARFrame to return a transform which, applied to normalized coordinate (0 to 1.0) inputs would produce output suitable to the viewPort coordinate system. Instead, applying the transform to normalized coordinates produces output which are also normalized.

The documentation at does not make it clear that the transform returned produces normalized output.
