  24 /**
  25  * Test that when target is TEXTURE_RECTANGLE, the correct error messages are
  26  * generated when certain texture parameter values are specified.
  27  *
  28  * Section 8.10 (Texture Parameters) of the OpenGL 4.5 Core spec (30.10.2014)
  29  * says:
  30  *      "An INVALID_ENUM error is generated if the effective target is
  31  *      TEXTURE_RECTANGLE and either of pnames TEXTURE_WRAP_S or
  32  *      TEXTURE_WRAP_T is set to either MIRROR_CLAMP_TO_EDGE , MIRRORED_REPEAT
  33  *      or REPEAT."
  34  *
  35  *      "An INVALID_ENUM error is generated if the effective target is
  36  *      TEXTURE_RECTANGLE and pname TEXTURE_MIN_FILTER is set to a value other
  37  *      than NEAREST or LINEAR (no mipmap filtering is permitted)."
  38  *
  39  *      "An INVALID_OPERATION error is generated if the effective target is
  40  *      TEXTURE_RECTANGLE and pname TEXTURE_BASE_LEVEL is set to any value
  41  *      other than zero."
  42  *
  43  * Note that the third error condition above directly conflicts with what
  44  * Section 3.8.8(Texture Parameters) of OpenGL 3.3 Core says:
  45  *
  46  *     "When target is TEXTURE_RECTANGLE, certain texture parameter values may
  47  *     not be specified. In this case, the error INVALID_ENUM is generated if
  48  *     the TEXTURE_WRAP_S, TEXTURE_WRAP_T, or TEXTURE_WRAP_R parameter is set
  49  *     to REPEAT or MIRRORED_REPEAT. The error INVALID_ENUM is generated if
  50  *     TEXTURE_MIN_FILTER is set to a value other than NEAREST or LINEAR (no
  51  *     mipmap filtering is permitted). The error INVALID_VALUE is generated if
  52  *     TEXTURE_BASE_LEVEL is set to any value other than zero."
  53  *
  54  * This conflict is resolved in favor of the GL 4.5 spec because the OpenGL ES
  55  * 3.1 spec (Section 8.10, Texture Queries, 29.10.2014) says:
  56  *
  57  *      "An INVALID_OPERATION error is generated if target is
  58  *      TEXTURE_2D_MULTISAMPLE, and pname TEXTURE_BASE_LEVEL is set to a
  59  *      value other than zero."
  60  *
  61  * Therefore, the change from INVALID_VALUE to INVALID_OPERATION moves OpenGL
  62  * toward improved consistency.
  63  *
  64  *
  65  * The GL_ATI_texture_mirror_repeat_once spec is silent on the topic of
  66  * rectangle textures, but GL_ARB_texture_mirror_clamp_to_edge says:
  67  *
  68  *     "The error INVALID_ENUM is generated when TexParameter* is called with
  69  *     a target of TEXTURE_RECTANGLE and the TEXTURE_WRAP_S, TEXTURE_WRAP_T,
  70  *     or TEXTURE_WRAP_R parameter is set to REPEAT, MIRRORED_REPEAT, or
  71  *     MIRROR_CLAMP_TO_EDGE."
  72  *
  73  * And GL_NV_texture_mirror_clamp says:
  74  *
  75  *     "Certain texture parameter values may not be specified for textures
  76  *     with a target of TEXTURE_RECTANGLE_NV.  The error INVALID_ENUM is
  77  *     generated if the target is TEXTURE_RECTANGLE_NV and the TEXTURE_WRAP_S,
  78  *     TEXTURE_WRAP_T, or TEXTURE_WRAP_R parameter is set to REPEAT,
  79  *     MIRRORED_REPEAT_IBM, MIRROR_CLAMP_EXT, MIRROR_CLAMP_TO_EDGE_EXT, and
  80  *     MIRROR_CLAMP_TO_BORDER_EXT."
  81  *
  82  * So also verify that the GL_MIRROR_CLAMP_* values also generate
  83  * GL_INVALID_ENUM.  Note that we don't need to check for the extensions for
  84  * this test.  If the extensions are not supported, the values should generate
  85  * GL_INVALID_ENUM anyway!
