64   surface's layout in memory.
66   A surface's width and height, in units of logical pixels, is not affected by
67   the surface's sample count. For example, consider a VkImage created with
68   VkImageCreateInfo{width=w0, height=h0, samples=s0}. The surface's width and
72   For example, the logical array length of a 3D surface is always 1, even on
73   Gen9 where the surface's memory layout is that of an array surface
78   For a multisampled surface, this unit has the obvious meaning.
79   A singlesampled surface, from ISL's perspective, is simply a multisampled
80   surface whose sample count is 1.
82   For example, consider a 2D single-level non-array surface with samples=4,
84   pixels). If the surface's multisample layout is ISL_MSAA_LAYOUT_INTERLEAVED,
85   then the extent of level 0 is, in units of physical surface samples,
95   If the surface's pixel format is compressed, such as ETC2, then a surface
97   a surface element is equivalent to a surface sample. As a corollary, for
98   a given surface a surface element is at least as large as a surface sample.
102 ISL acquired the term 'surface element' from the Broadwell PRM [1], which
105    An element is defined as a pixel in uncompresed surface formats, and as
106    a compression block in compressed surface formats. For MSFMT_DEPTH_STENCIL
