from Gabriel:
- through use of RetrieveBinContent / GetBinErrorSqUnchecked and code cleanup -> achieved a 1.5x-2x speedup for TH1::Chi2Test
- reverted changes made to GetBinContent methods for 2 or 3 dimensions: these should still call TH1::GetBinContent since it is possible to have to call BufferEmpty
- made TAxis::GetLabels const -> as a consequence, deleted unnecessary const casts in TH1 code
- replaced GetBinError(bin) * GetBinError(bin) with GetBinErrorSqUnchecked(bin) in TH1::Merge

from Gabriel:
Introduce possibility to rebin each axis individually
see https://savannah.cern.ch/bugs/?89628
Added a new bit in TAxis to tag an axis as alphanumeric
(i.e. when it contains only labels)
fixed kDecimal problem. Put now as Bit 7 of TObject bits, instead of using TAxis::fBits2
Add new methods:
TH1::SetCanRebin() which can enable/disable rebinning for all axes or for each axis individually
This will replace the TH1::kCanRebin bit which will be deprecated
TH1::CanRebinAllAxes() added to provide the functionality of TestBit(TH1::kCanRebin)
inline some TAxis methods
update stressHistogram to use new methods SetCanRebin and CanRebin

Remove
using namespace std;
from Riostream.h, which has huge consequences for all of ROOT.
Riostream.h is now a simple wrapper for fstream, iostream, iomanip for backward compatibility; Riosfwd.h simply wraps iosfwd.
Because of templates and their inline functions, Riostream.h needed to be included in headers, too (e.g. TParameter.h), which violated the assumption that Riostream.h is not exposing its using namespace std to headers.
ROOT now requires R__ANSISTREAM, R__SSTREAM, which does not change the set of supported compilers.
Without "using namespace std", several identifiers are now prefixed by std::; e.g. roofit/* source files now have a using namespace std to keep their coding style.
TFile::MakeProject() now generates "using namespace std" to convert the CINT-style class names into C++ ones.

From Chris Crawford. see : https://savannah.cern.ch/patch/?3978
Implement a new function (also in context menu)
void TAxis::ZoomOut(Double_t factor, Double_t offset)
// Zoom out by a factor of 'factor' (default =2)
// uses previous zoom factor by default
// Keep center defined by 'offset' fixed
// ie. -1 at left of current range, 0 in center, +1 at right

Implement a new function as suggested at http://root.cern.ch/phpBB2/viewtopic.php?t=8263
Double_t TAxis::GetBinCenterLog(Int_t bin) const
{
// Return center of bin in log
// With a log-equidistant binning for a bin with low and up edges, the mean is :
// 0.5*(ln low + ln up) i.e. sqrt(low*up) in logx (e.g. sqrt(10^0*10^2) = 10).
//Imagine a bin with low=1 and up=100 :
// - the center in lin is (100-1)/2=50.5
// - the center in log would be sqrt(1*100)=10 (!=log(50.5))
// NB: if the low edge of the bin is negative, the function returns the bin center
// as computed by TAxis::GetBinCenter

From Federico Carminati:
"I have implemented all copy and equal operators needed to silence all
warnings in AliRoot, as requested. I have implemented shallow copies as
would do the default operators synthetized by the compiler.
Most operators are protected. If users complain, you just have to move
them into the public area, but class derivation is of course supported.
It has been a terrible job, I have modified 278 files, but the changes
are backward compabile, and this goes a long way to permitting user to
use the effc++ flag with root headers."

In TAxis class
==============
Add a new data member
UShort_t fBits2; //second bit status word
Add new enum kDecimals
Add new functions:
Bool_t GetDecimals() const;
virtual void SetDecimals(Bool_t dot=kTRUE); // *TOGGLE*
// Set the Decimals flag
// By default, blank characters are stripped, and then the
// label is correctly aligned. The dot, if last character of the string,
// is also stripped, unless this option is specified.
// One can disable the option by calling axis.SetDecimals(kTRUE).
// The flag (in fBits2) is passed to the drawing function TGaxis::PaintAxis
in TGaxis class
===============
Add new function:
virtual void SetDecimals(Bool_t dot=kTRUE);
(same as TAxis::SetDecimals)
Modify TGaxis::PaintAxis to take into account the SetDecimals:
// Format of labels.
// -----------------
//
// Blank characters are stripped, and then the
// label is correctly aligned. the dot, if last
// character of the string, is also stripped,
// unless the option "." (a dot, or period) is specified.
// if SetDecimals(kTRUE) has been called (bit TAxis::kDecimals set).
// all labels have the same number of decimals after the "."
// The same is true if gStyle->SetStripDecimals(kFALSE) has been called.

From Olivier:
Implement suggestion from Damir Buskulic:
- Take into account the decimal part of the time offset.
- New parameter "option" in SetTimeOffset. Default value is "local"
meaning the time offset should be consider as a local time. It can
be set to "gmt" meaning the time offset should be consider as GMT time.

Add new function TAxis::SetMoreLogLabels to draw more labels in case
of an axis in log scale with a small number of decades.
The options is kept in TAxis via the new bit kMoreLogLabels.
The corresponding changes in TGaxis to automatically import the TAxis option.
The bits in TGaxis duplicating the bits in TAxis have been removed.
The new function SetMoreLogLabels is visible in the TAxis context menu.

Add a new option in TAxis and TGaxis to center the bin labels
on the center of the bin instead of the tick marks.
This option makes sense only when the number of bins is equal
to the number of tick marks.
The new function TAxis::CenterLabels sets the bit kCenterLabels.
CenterLabels is visible in the TAxis context menu.

W A R N I N G !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
==================================================================
A very long list of changes in this pre-release of version 3.00.
We have modified the signature of many functions (in particular TObject)
to introduce more constness in the system.
You must change your code if your class derives from TObject and uses
one of the modified functions such as ls, Print, Compare, Hash, etc.
The modified functions in TObject have the following signature:
virtual TObject *Clone() const;
virtual Int_t Compare(const TObject *obj) const;
virtual void Delete(Option_t *option=""); // *MENU*
virtual void DrawClass() const; // *MENU*
virtual void DrawClone(Option_t *option="") const; // *MENU*
virtual void Dump() const; // *MENU*
virtual TObject *FindObject(const TObject *obj) const;
virtual char *GetObjectInfo(Int_t px, Int_t py) const;
virtual ULong_t Hash() const;
virtual void Inspect() const; // *MENU*
virtual Bool_t IsEqual(const TObject *obj) const;
virtual void ls(Option_t *option="") const;
virtual void Print(Option_t *option="") const;
A similar operation has been done with classes such as TH1, TVirtualPad,
TTree, etc.
