  25  * Tests the TEXTURE_IMMUTABLE_LEVELS parameter.
  26  *
  27  * The GL ES 3.0 spec says:
  28  *
  29  *     "If the command is successful, TEXTURE_IMMUTABLE_FORMAT becomes
  30  *      TRUE and TEXTURE_IMMUTABLE_LEVELS becomes levels."
  31  *
  32  * where <command> is either glTexStorage2D or glTexStorage3D.
  33  *
  34  * Test by calling glTexStorage*D with <levels> = 3, <width>, <height>, and
  35  * <depth> = 32; and then confirming that TEXTURE_IMMUTABLE_LEVELS was
  36  * correctly set to <levels>.
