      - TFormula::EvalPar() is not changing parameters (the fParams data member) when a user passes his own uparams array as a second argument. Before - sometimes it did, sometimes it didn't.
      - TF1::GradientPar() is now 0 on fixed parameters
      - TFitter::GetConfidenceIntervals() is now taking the fixed parameters into account
      - TLinearFitter::GetConfidenceIntervals()  is now taking the fixed parameters into account
      - TLinearFitter::FixParameter() can now be called before a first fit is performed (an accidently found bug :))
      - TLinearFitter::Eval() now returns 1 if there are errors in the fit. According changes in:
        --TH1
        --TGraph
        --TGraph2D
        --TMultiGraph

        Fixes for few bugs in reading multi-image gif files by
        Sasha Vasko and Valeriy Onuchin
      
      - TASImage.cxx
        o Several image formats can support subimages e.g.
          GIF, TIFF, BMP, XCF, ICO etc. The famous ones are
          animated GIF files.
          Possiblity to read subimages from multi-image files added.
            For example,
              i1 = TImage::Open("anim.gif.0"); // read the first subimage
              i2 = TImage::Open("anim.gif.1"); // read the second subimage
              i4 = TImage::Open("anim.gif.3"); // read the forth subimage
      
        o TASImage::Draw method. Take into account the
          gStyle->GetScreenFactor() when a new canvas displaing an image is created.
      
      - TImageDump.cxx
        o Small correction in comment

      extend functionality of TFormula::GetExpFormula, adding an optional argument · 7b36a6d8
      Rene Brun authored
      TString TFormula::GetExpFormula(Option_t *option) const
      //*-*  if option contains "p" the returned string will contain the formula
      //*-*  expression with symbolic parameters, eg [0] replaced by the actual value
      //*-*  of the parameter. Example:
      //*-*  if expression in formula is: "[0]*(x>-[1])+[2]*exp(-[3]*x)"
      //*-*  and parameters are 3.25,-4.01,4.44,-0.04, GetExpFormula("p") will return:
      //*-*   "(3.25*(x>+4.01))+(4.44*exp(+0.04*x))"
