/*    Implementation of (Test 7) from CTS_EXT_texture_buffer. Description follows:
 *
 *    Test whether functions TexBufferEXT and TexBufferRangeEXT generate errors
 *    as specified in the extension specification.
 *
 *    Category: API.
 *              Dependency with OES_texture_storage_multisample_2d_array
 *
 *    Check if for all targets apart from TEXTURE_BUFFER_EXT functions
 *    TexBufferEXT and TexBufferRangeEXT report INVALID_ENUM error.
 *
 *    Check if for GL_DEPTH_COMPONENT32F internal format functions
 *    TexBufferEXT and TexBufferRangeEXT report INVALID_ENUM error.
 *
 *    Check if for buffer id not previously returned by genBuffers and
 *    not equal to zero functions TexBufferEXT and TexBufferRangeEXT report
 *    INVALID_OPERATION error.
 *
 *    Check if for offset parameter that is negative, size parameter that is less
 *    than or equal to zero or offset + size that is greater than the value of
 *    GL_BUFFER_SIZE for the buffer object bound to TEXTURE_BUFFER_EXT target
 *    function TexBufferRangeEXT reports INVALID_VALUE error.
 *
 *    Check if in case of offset parameter not being an integer multiple of
 *    value(TEXTURE_BUFFER_OFFSET_ALIGNMENT_EXT) function TexBufferRangeEXT
 *    reports INVALID_VALUE error.
