[Piglit] [PATCH 2/2] texture_rectangle: Also test the other mirror wrap modes

[Ian Romanick]

From: Ian Romanick <ian.d.romanick at intel.com>

These aren't part of GL 3.3, but they should generate GL_INVALID_ENUM
when used.

  *     TEXTURE_MIN_FILTER is set to a value other than NEAREST or LINEAR (no
  *     mipmap filtering is permitted). The error INVALID_VALUE is generated if
  *     TEXTURE_BASE_LEVEL is set to any value other than zero."
+ *
+ * The GL_ATI_texture_mirror_repeat_once spec is silent on the topic of
+ * rectangle textures, but GL_ARB_texture_mirror_clamp_to_edge says:
+ *
+ *     "The error INVALID_ENUM is generated when TexParameter* is called with
+ *     a target of TEXTURE_RECTANGLE and the TEXTURE_WRAP_S, TEXTURE_WRAP_T,
+ *     or TEXTURE_WRAP_R parameter is set to REPEAT, MIRRORED_REPEAT, or
+ *     MIRROR_CLAMP_TO_EDGE."
+ *
+ * And GL_NV_texture_mirror_clamp says:
+ *
+ *     "Certain texture parameter values may not be specified for textures
+ *     with a target of TEXTURE_RECTANGLE_NV.  The error INVALID_ENUM is
+ *     generated if the target is TEXTURE_RECTANGLE_NV and the TEXTURE_WRAP_S,
+ *     TEXTURE_WRAP_T, or TEXTURE_WRAP_R parameter is set to REPEAT,
+ *     MIRRORED_REPEAT_IBM, MIRROR_CLAMP_EXT, MIRROR_CLAMP_TO_EDGE_EXT, and
+ *     MIRROR_CLAMP_TO_BORDER_EXT."
+ *
+ * So also verify that the GL_MIRROR_CLAMP_* values also generate
+ * GL_INVALID_ENUM.  Note that we don't need to check for the extensions for
+ * this test.  If the extensions are not supported, the values should generate
+ * GL_INVALID_ENUM anyway!
