-/* Texture Layout on a3xx:
- *
- * Each mipmap-level contains all of it's layers (ie. all cubmap
- * faces, all 1d/2d array elements, etc).  The texture sampler is
- * programmed with the start address of each mipmap level, and hw
- * derives the layer offset within the level.
- *
- * Texture Layout on a4xx:
- *
- * For cubemap and 2d array, each layer contains all of it's mipmap
- * levels (layer_first layout).
- *
- * 3d textures are layed out as on a3xx, but unknown about 3d-array
- * textures.
- *
- * In either case, the slice represents the per-miplevel information,
- * but in layer_first layout it only includes the first layer, and
- * an additional offset of (rsc->layer_size * layer) must be added.
