- The signatures of the two SetPointError methods were incomplete. The shift

  values in the various directions were missing. To preserve the backward 
  compatibility, the missing parameters have been added with default value = 0.
  The new signature is now used in SavePrimitive which allows a correct saving
  of the TGraphBentErrors.
