/**
* Test that when target is TEXTURE_RECTANGLE, the correct error messages are
* generated when certain texture parameter values are specified.
*
* Section 3.8.8(Texture Parameters) of OpenGL 3.3 Core says:
*
* "When target is TEXTURE_RECTANGLE, certain texture parameter values may
* not be specified. In this case, the error INVALID_ENUM is generated if
* the TEXTURE_WRAP_S, TEXTURE_WRAP_T, or TEXTURE_WRAP_R parameter is set
* to REPEAT or MIRRORED_REPEAT. The error INVALID_ENUM is generated if
* 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!
