  25  *
  26  * From the GL_ARB_uniform_buffer_object spec:
  27  *
  28  *     "If any index is greater than or equal to the value of
  29  *      ACTIVE_UNIFORMS, the error INVALID_VALUE is generated.
  30  *
  31  *      For GetActiveUniformsiv, <uniformCount> indicates both the
  32  *      number of elements in the array of indices <uniformIndices>
  33  *      and the number of parameters written to <params> upon
  34  *      successful return.  <pname> identifies a property of each
  35  *      uniform in <uniformIndices> that should be written into the
  36  *      corresponding element of <params>.  If an error occurs,
  37  *      nothing will be written to <params>.
  38  *
  39  *      The error INVALID_VALUE is generated by GetUniformIndices,
  40  *      GetActiveUniformsiv, GetActiveUniformName,
  41  *      GetUniformBlockIndex, GetActiveUniformBlockiv,
  42  *      GetActiveUniformBlockName, and UniformBlockBinding if
  43  *      <program> is not a value generated by GL.
  44  *
  45  *      The error INVALID_ENUM is generated by GetActiveUniformsiv and
  46  *      GetActiveUniformBlockiv if <pname> is not one of the accepted
  47  *      values."
