Not quite. Depth-stencil formats are weird because they describe two
different things at the same time. In our hardware (post Sandy Bridge) the
depth and stencil components are actually stored in different surfaces but
in the same VkImage.  We certainly can handle 32-bit depth with stencil, we
just need to get the blits working.
