> + * \file
> + * \brief Test texturing from an ASTC miptree of a real image.
> + *
> + * The files under compressed/SLICED3D/{hdr, ldrl, ldrs} contain full miptrees,
> + * in the GL_*_ASTC_* formats, of a sliced 3D texture of waffles and fruit [1].
> + * The base level size was shrunken to 160x106 pixels. The files under the
> + * decompressed/SLICED3D/{hdr, ldrl, ldrs} directory contain the same miptree in
> + * GL_RGBA format. Each miplevel was obtained by decompressing the corresponding
> + * ASTC texture with astcenc [2].
> + *
> + * This test draws miplevels of the compressed textures in a space-efficient
> + * manner. It does the same when drawing the decompressed texture on the right.
> + * Each miplevel of both images are compared for equality after being drawn.
> + *
> + * [1] The reference image is located at:
> + * http://people.freedesktop.org/~chadversary/permalink/2012-07-09/1574cff2-d091-4421-a3cf-b56c7943d060.jpg.
> + * [2] astcenc is the reference ASTC compression tool, available at:
> + * http://malideveloper.arm.com/develop-for-mali/tools/software-tools/astc-evaluation-codec/.
