48 * For cubemap and 2d array, each layer contains all of it's mipmap

51 * 3d textures are layed out as on a3xx, but unknown about 3d-array
54 * In either case, the slice represents the per-miplevel information,
55 * but in layer_first layout it only includes the first layer, and
56 * an additional offset of (rsc->layer_size * layer) must be added.
