From: Nanley Chery <nanley.g.ch...@intel.com>
These tests run through every ASTC configuration, comparing the
render of a compressed texture against a render of the decompressed
version of that compressed texture. The compressed and decompressed
texture was generated with a reference codec.
v2. numerous changes (Chad).
v3. upgrade required GLES version to 2.

+/**
+ * \file
+ * \brief Test texturing from an ASTC miptree of a real image.
+ *
+ * This test is an adaptation of the oes_compressed_etc1_rgb8_textures test.
+ *
+ * The files under compressed/ contain full miptrees, in the
+ * GL_*_ASTC_* formats, of a 2D texture of waffles and fruit [1]. The base
+ * level size was shrunken to 160x106 pixels. The files under the decompressed
+ * 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/.
