  25  *
  26  * From the GL_ARB_uniform_buffer_object spec:
  27  *
  28  *     "<uniformBlockIndex> is an active uniform block index of
  29  *      <program>.  If <uniformBlockIndex> is greater than or equal to
  30  *      the value of ACTIVE_UNIFORM_BLOCKS, or is not the index of an
  31  *      active uniform block in <program>, the error INVALID_VALUE is
  32  *      generated.
  33  *
  34  *      If no error occurs, the uniform block parameter(s) specified
  35  *      by <pname> are returned in <params>. Otherwise, nothing will
  36  *      be written to <params>.
  37  *
  38  *      The error INVALID_VALUE is generated by GetUniformIndices,
  39  *      GetActiveUniformsiv, GetActiveUniformName,
  40  *      GetUniformBlockIndex, GetActiveUniformBlockiv,
  41  *      GetActiveUniformBlockName, and UniformBlockBinding if
  42  *      <program> is not a value generated by GL.
  43  *
  44  *      The error INVALID_ENUM is generated by GetActiveUniformsiv and
  45  *      GetActiveUniformBlockiv if <pname> is not one of the accepted
  46  *      values."
