What hardware are you running on? Prior to sky lake, depth pitch makes so
sense for us. On sky lake and above it should be exactly the same as array
pitch. One thing we should do is not report array pitch for 3D and maybe
report a depth pitch of zero on broadwell and earlier.

With a 3d image of 2x2x3, vkGetImageSubresourceLayout currently reports :
VkSubresourceLayout = { offset = 0,
size = 160,
rowPitch = 16,
arrayPitch = 96,
depthPitch = 96 }
depthPitch should be 32.
