* \brief ASTC decompression tests
*
* \todo Parts of the block-generation code are same as in decompression
* code in tcuCompressedTexture.cpp ; could put them to some shared
* ASTC utility file.
*
* \todo Tests for void extents with nontrivial extent coordinates.
*
* \todo Better checking of the error color. Currently legitimate error
* pixels are just ignored in image comparison; however, spec says
* that error color is either magenta or all-NaNs. Can NaNs cause
* troubles, or can we assume that NaNs are well-supported in shader
* if the implementation chooses NaNs as error color?
