/**
* \file texture-compressed-block.c
*
* Verify conditions defined on the spec for the following pnames:
* * TEXTURE_COMPRESSED_BLOCK_WIDTH
* * TEXTURE_COMPRESSED_BLOCK_HEIGHT
* * TEXTURE_COMPRESSED_BLOCK_SIZE
*
* In all those three the spec says :
*
* "If the internal format is not compressed, or the resource is not
* supported, 0 is returned."
*
* One could guess which internalformats are compressed, but
* TEXTURE_COMPRESSED is already there to know that.
*
* So this test just verifies that if TEXTURE_COMPRESSED or
* INTERNALFORMAT_SUPPORTED are false, all those pnames should return
* 0.
*
* In that sense, this test is generic-pname-checks on those pnames,
* plus a TEXTURE_COMPRESSED check.
