// (1) RT Alignment (GMM Don't Care: Occurs Naturally)
// (2) ClearRect Alignment
// (3) ClearRect Scaling (GMM Don't Care: GHAL3D Matter)
// (4) Non-MSAA CCS Sizing
// Gen8+:
// Since mip-mapped and arrayed surfaces are supported, we
// deal with alignment later at per mip level. Here, we set
// tiling type only. TileX is not supported on Gen9+.
// Pre-Gen8:
// (!) For all the above, there are separate entries for
// 32/64/128bpp--and then deals with PIXEL widths--Here,
// though, we will unify by considering 8bpp table entries
// (unlisted--i.e. do the math)--and deal with BYTE widths.
// (1) RT Alignment -- The surface width and height don't
// need to be padded to RT CL granularity. On HSW, all tiled
// RT's will have appropriate alignment (given 4KB surface
// base and no mip-map support) and appropriate padding
// (due to tile padding). On BDW+, GMM uses H/VALIGN that
// will guarantee the MCS RT alignment for all subresources.
// (2) ClearRect Alignment -- I.e. FastClears must be done
// with certain granularity:
// TileY: 512 Bytes x 128 Lines
// TileX: 1024 Bytes x 64 Lines
// So a CCS must be sized to match that granularity (though
// the RT itself need not be fully padded to that
// granularity to use FastClear).
// (4) Non-MSAA CCS Sizing -- CCS sizing is based on the
// size of the FastClear (with granularity padding) for the
// paired RT. CCS's (byte widths and heights) are scaled
// down from their RT's by:
// TileY: 32 x 32
// TileX: 64 x 16
// ### Example #############################################
