524 * Surfaces are hierarchial:
526 * - Surface may have multiple faces (for cube maps)
528 * - Each face has a list of mipmap levels
530 * - Each mipmap image may have multiple volume
531 * slices for 3D image, or multiple 2D slices for texture array.
533 * - Each slice is a 2D array of 'blocks'
535 * - Each block may be one or more pixels.

538 * Surfaces are generic host VRAM objects. The SVGA3D device
539 * may optimize surfaces according to the format they were
540 * created with, but this format does not limit the ways in
541 * which the surface may be used. For example, a depth surface
542 * can be used as a texture, or a floating point image may
543 * be used as a vertex buffer. Some surface usages may be
544 * lower performance, due to software emulation, but any
545 * usage should work with any surface.
