  26  *
  27  * Verify conditions defined on the spec for the following pnames:
  28  *  * TEXTURE_COMPRESSED_BLOCK_WIDTH
  29  *  * TEXTURE_COMPRESSED_BLOCK_HEIGHT
  30  *  * TEXTURE_COMPRESSED_BLOCK_SIZE
  31  *
  32  * In all those three the spec says :
  33  *
  34  * "If the internal format is not compressed, or the resource is not
  35  *  supported, 0 is returned."
  36  *
  37  * One could guess which internalformats are compressed, but
  38  * TEXTURE_COMPRESSED is already there to know that.
  39  *
  40  * So this test just verifies that if TEXTURE_COMPRESSED or
  41  * INTERNALFORMAT_SUPPORTED are false, all those pnames should return
  42  * 0.
  43  *
  44  * In that sense, this test is generic-pname-checks on those pnames,
  45  * plus a TEXTURE_COMPRESSED check.
