505 * containers for host VRAM objects like textures, vertex
506 * buffers, and depth/stencil buffers.
508 * Surfaces are hierarchial:
510 * - Surface may have multiple faces (for cube maps)
512 * - Each face has a list of mipmap levels
514 * - Each mipmap image may have multiple volume
515 * slices for 3D image, or multiple 2D slices for texture array.
517 * - Each slice is a 2D array of 'blocks'
519 * - Each block may be one or more pixels.
520 * (Usually 1, more for DXT or YUV formats.)
522 * Surfaces are generic host VRAM objects. The SVGA3D device
523 * may optimize surfaces according to the format they were
524 * created with, but this format does not limit the ways in
525 * which the surface may be used. For example, a depth surface
526 * can be used as a texture, or a floating point image may
527 * be used as a vertex buffer. Some surface usages may be
528 * lower performance, due to software emulation, but any
529 * usage should work with any surface.
