[Mesa-dev] [PATCH] anv: image: report correct depthPicth for 3d images

[Lionel Landwerlin]

With a 3d image of 2x2x3, vkGetImageSubresourceLayout currently reports :

VkSubresourceLayout = { offset = 0,
                        size = 160,
                        rowPitch = 16,
                        arrayPitch = 96,
                        depthPitch = 96 }

depthPitch should be 32.
