/**  Implementation of Test 6 from CTS_EXT_texture_border_clamp. Description follows
 *
 *    Verify that GL_TEXTURE_BORDER_COLOR_EXT state is correctly retrieved
 *    by glGetSamplerParameter*() and glGetTexParameter*() functions.
 *
 *    Category: Functional tests;
 *              Optional dependency on EXT_texture_cube_map_array.
 *    Priority: Must-have.
 *
 *    Verify default border color is set to (0.0, 0.0, 0.0, 0.0) and
 *    (0, 0, 0, 0).
 *
 *    Verify setting signed integer border color of (-1, -2, 3, 4) using
 *    glSamplerParameterIivEXT() / glTexParameterIivEXT() call affects the values
 *    later reported by glGetSamplerParameterIivEXT() and glGetTexParameterIivEXT().
 *    These values should match.
 *
 *    Verify setting unsigned integer border color of (1, 2, 3, 4) using
 *    glSamplerParameterIuivEXT() / glTexParameterIuivEXT() call affects the values
 *    later reported by glGetSamplerParameterIuivEXT() and glGetTexParameterIuivEXT().
 *    These values should match.
 *
 *    Verify setting floating-point border color of (0.1, 0.2, 0.3, 0.4)
 *    affects the values later reported by glGetSamplerParameterfv() /
 *    glGetTexParameterfv(). These values should match.
 *
 *    Verify setting integer border color of
 *    (0, 1, 2, 4) using glSamplerParameteriv()
 *    / glTexParameteriv() affects the values later reported by
 *    glGetSamplerParameteriv() / glGetTexParameteriv(). The returned values
 *    should correspond to the outcome of equation 2.2 from ES3.0.2 spec
 *    applied to each component.
 *
 *    All texture targets available in ES3.1, as well as
 *    GL_TEXTURE_CUBE_MAP_ARRAY_EXT (if supported).
