  25  * Tests the TEXTURE_IMMUTABLE_LEVELS and TEXTURE_VIEW_NUM_LEVELS parameters.
  26  *
  27  * The ARB_texture_view spec says:
  28  *
  29  *     "If the command is successful, TEXTURE_IMMUTABLE_FORMAT becomes TRUE,
  30  *      TEXTURE_IMMUTABLE_LEVELS and TEXTURE_VIEW_NUM_LEVELS become <levels>."
  31  *
  32  * where <command> is glTexStorage?D.
  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>.
