Split Depth Stencil Aspects: Depth pixel stride includes stencil or uses stencil row pitch · case 04

The returned physical layout descriptor disagrees with the declared buffer mapping at depth_address.

Case contract

A toy depth-stencil image stores three depth bytes per texel in one plane and one stencil byte per texel in a second plane. Depth rows have one pad byte, stencil rows two; planes begin with distinct four- and six-byte tags. Return the named intermediate layout descriptor and final address fields; all quantities are integer byte offsets unless explicitly stated.
