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

- Add in THistPainter::GetObjectInfo the case of TProfile2D to print also bin entries and bin error
and disable printing bin information for 3D objects. Print in that case only x and y
_ Remove TProfile::GetObjectInfo, use now the inherited one from TH1 which is impelmented using THistPainter::GetObjectInfo

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.

aaply patch from Andrei to have a lazy allocation of the TArray[x] of histograms and profiles.
The allocation is done only if a SetBinContent() or AddBinContent() is called.
This feature can be activated via the static TH1::SetLazyAllocation(kTRUE)

merge changes from development branch done mainly by David
TH1
- Add a method, TH1::ResetStats() to reset the internal statistics and force then the re-calculation suing the bin center first time is needed
- Fix some problem with the statistics (in particular the number of entries) after some of the histogram operations
TH2
Consider in the projection of TH2 the axis range set by the user. This fix the issue https://savannah.cern.ch/bugs/index.php?47946
TH3
- Add TH3::ProjectionX and TH3::ProjectionY to complement the already existing ProjectionZ. They are all impelmented using the Project3D method.
- Re-implement the TH3::Project3D method using the internal methods DoProject1D and DoProject2D depending on the option. This new implementation is faster in case sub-ranges are selected and fix this issue (https://savannah.cern.ch/bugs/index.php?45494). A similar new implementation is done for TH3::ProjectProfile.
TProfile, TProfile2D
Fix a bug in GetStats method.
WrappedTF1, WrappedMultiTF1
- make possiible to wrap TF1 objects defined with dimension N ( N > 3) and return correct dimension
- fix a problem with a static data member on Windows

merge changes from math development branch.
In details the changes are
TH1
-----
add new functions IsBinUnderflow(bin), IsBinOverflow(bin) using global bin number
- fix a problem in TH1::Sumw2() when called from constructor of TProfile()
TProfile,TProfile2D and TProfile3D
----------------------------------
- add a new data member (TArrayD fBinSumw2) for storing the sum of weight square per bin. This is needed for correct error calculation in case of profile filled with weights different than 1. The new structure is filled only when TProfile::Sumw2() is called or when TH1::SetDefaultSumw2() is set.
- at the same time the TProfile classes have been improved by factoring out some common implementations of some methods like Add and Merge
TH2, TH3
------------------
change projection into TProfile's in case Sumw2() is set to correctly project the
errors.

define kNStat as an enumeration in TH1 and not as a static type in all the implementation classes.
This avoids having wrong values of kNstat.
Before we had in TH1 kNstat=11, instead of 13, the value needed by TProfile3D.
This bug was found by running stressHistogram with a TProfile3D

- implement in the Profile the existing option G to get the bin error in the case of combination of measurements y
with gaussian error dy. In this case the profile must be filled
with a weight = 1./dy**2 and the correct error from the combination (1./sqrt(Sum(1./dy**2) ) ) will be obtained.
This option was requested by Yuri Fisyak.

- merge implementation from David of TH2::ProjectionX and TH2::ProjectionY in a common method
- fix a coubple of bugs in projections of TH3 found thanks to the new projection test from David
- improve KolmogorvSmirnov test in 2D and 3D. Make it also working for weighted histograms.
For the 3D tests use as probing max distance the one obtained using all possible axis combination for the order.
It is arbitrary (as in the 2D case), but at least consistent. A better method, like the one proposed by Peacock,
should be used for the multi-dim KS test.
- add some extra comments for projections of profiles to histograms using option "W". Fix also an un-wanted
extra calls to Sumw2()

Add a new optional argument to TH1::Rebin and TProfile::Rebin.
This new argument can be used to rebin a fixed bin histogram into a variable bin size histogram.
TH1 *TH1::Rebin(Int_t ngroup, const char*newname, const Double_t *xbins)
// -case 1 xbins=0
// if newname is not blank a new temporary histogram hnew is created.
// else the current histogram is modified (default)
// The parameter ngroup indicates how many bins of this have to me merged
// into one bin of hnew
// If the original histogram has errors stored (via Sumw2), the resulting
// histograms has new errors correctly calculated.
//
// examples: if h1 is an existing TH1F histogram with 100 bins
// h1->Rebin(); //merges two bins in one in h1: previous contents of h1 are lost
// h1->Rebin(5); //merges five bins in one in h1
// TH1F *hnew = h1->Rebin(5,"hnew"); // creates a new histogram hnew
// //merging 5 bins of h1 in one bin
//
// NOTE: If ngroup is not an exact divider of the number of bins,
// the top limit of the rebinned histogram is changed
// to the upper edge of the bin=newbins*ngroup and the corresponding
// bins are added to the overflow bin.
// Statistics will be recomputed from the new bin contents.
//
// -case 2 xbins!=0
// a new histogram is created (you should specify newname).
// The parameter is the number of variable size bins in the created histogram.
// The array xbins must contain ngroup+1 elements that represent the low-edge
// of the bins.
// If the original histogram has errors stored (via Sumw2), the resulting
// histograms has new errors correctly calculated.
//
// examples: if h1 is an existing TH1F histogram with 100 bins
// Double_t xbins[25] = {...} array of low-edges (xbins[25] is the upper edge of last bin
// h1->Rebin(24,"hnew",xbins); //creates a new variable bin size histogram hnew

Check -> R__CHECK
Change the TCollection.h macro:

This to avoid potential problems due too trivial macro names.
The old macros will be removed in the next release. Currently
they will print out warning messages with the advice to move
to the new macro names.

From Valeriy Onuchin:
this patch fixes all compilation problems for
ROOT under windows with VC6 compiler.
- The main problem is that VC6 compiler does not recognize
"long long" type in rootcint generated dictionaries,
To fix this, wherever "long long" type was writen in dictionary file it was
replaced with native win32 "long long" type_string "__int64".
Modified files are: cint/src/val2a.c, cint/src/newlink.c, cint/src/Class.cxx
Other changes:
- many classes contained "list" variables.
That produced name_clash with std::list class name.
- many classes contained
for (int i=0; ..) {..}
for (int i=0; ..) {..}
which caused "duplication of initialisation" bug.
- gl/src/CsgOps.cxx had outside declared templated parameter used inside
internal function.
- TString Atoi, Atof - std namespace was removed.
_ TASimage - custom Streamer was changed. Reading/writing class version
was added. That allows to keep "future compatibility"/"schema evolution"
Demo files galaxy.root, gallery.root were rewritten.
- I rolled back changes in TGPicture class which are related to reading
of XPM files because of problems under win32.
- TASImage::GetMask method was reimplemented.
- libAfterImage.tar.gz - fix all compilation problem under win32 (vc6)

same limits. If the limits are different the overflows are ignored.
The same in TH2::Merge, TH3::Merge, TProfile::Merge and TProfile2D::Merge.
- Cleaning fHistogram (and this kind of) variables, so that the drawn
plots aren't deleted in the TProofDrawXXX's destructor.
- Removed TProofNTuple from TProofDrawTGraph.
- Put the initialization code of fFeedback and fPlayer (=MakePlayer())
in TProof in to Init().
- Added TGraph::Merge(). Added TPolyMarker3D::GetPoint(Int_t, Float&,
Float&, Float&).
- Removed TProofNTuple from TProofDrawPolyMarker3D.
- Fixed cleaning output lists after processing (set option = "nodelete").
Now the objects are on the player outputlist and are removed (but not
deleted) from the selector's outputlist.
- Fixed TPolyMarker3D::Merge() - it seems that nobody has ever tried to
run this function.
- Added setting tree attributes (like MarkerStyle, MarkerSize, LineColor etc.)
to a drawn TGraph and TPolyMarker3D in TProofDrawGraph and
TProofDrawPolyMarker3D.

From Marek Biskup:
major new PROOF developments:
- access to PROOF directly via the TChain interface (creating a TDSet
in the background).
- access to PROOF based trees via the TTreeViewer
- fully implemented the TChain/TDSet::Draw() interface.
- PROOF sessions can now be browsed via the TBrowser

From Gero Flucke:
I implemented the rebinning for histograms with variable bin sizes for
1-D, 2-D and 1D-profile hist.
The main task was to implement
TH1::SetBins(Int_t nx, const Axis_t *xBins);
and
TH1::SetBins(Int_t nx, const Axis_t *xBins, Int_t ny, const Axis_t *yBins);
analog to SetBins(Int_t nx, Axis_t xmin, Axis_t xmin ...) and to overwrite
the methods in TProfile(2D).
For 2-D hists I decided not to distinguish between hists that are variable
bin sized in only one or both dimensions, for simplicity.
For concistency I changed the TProfile::SetBins(...Double_t...) to
SetBins(...Axis_t...) since this is their signature in the bas class.
I fixed usage of strlen without checking for NULL-pointers. :-)
Note that I also removed a check in TH2::Rebin2D that I consider not to be
needed.

Upgrade the histogram buffer algorithm such that it can be used in a
coming version of the rebinner of the TH1,2 editors.
When the histogram buffer is active (TH1::SetBuffer has been called),
the buffer is kept alive as long as the number of entries can
be accomodated by the buffer.
When calling the Draw/Paint functions, the histogram is reset and
refilled from the buffer.
The buffer is also preserved by the I/O operations.
The calling sequence of TH1::BufferEmpty has been modified to support
3 cases instead of 2.
Int_t TH1::BufferEmpty(Int_t action)
// action = -1 histogram is reset and refilled from the buffer (called by THistPainter::Paint)
// action = 0 histogram is filled from the buffer
// action = 1 histogram is filled and buffer is deleted
// The buffer is automatically deleted when the number of entries
// in the buffer is greater than the number of entries in the histogram

Add a new static member
Bool_t fgStatOverflows;
and a corresponding setter
static void StatOverflows(Bool_t flag=kTRUE)
All histogram Fill functions modified to test this new flag.
By default the flag is off.
Note that the mean value/RMS is computed using the bins in the currently
defined range (see TAxis::SetRange). By default the range includes
all bins from 1 to nbins included, excluding underflows and overflows.
To force the underflows and overflows in the computation, one must
call the static function TH1::StatOverflows(kTRUE) before filling
the histogram.

Add a new static function
void TProfile::Approximate(Bool_t approx=kTRUE);
When the flag is true, the function GetBinError will approximate the bin error
with the average profile error on all bins in the following situation only:
- the number of bins in the profile is less than 1002
- the number of entries in the bin is small (<5)
- the estimated bin error is extremely small compared to the bin content.
By default GetBinError does not make this approximation.

mega patch to remove almost all compiler warnings on MacOS X where the
compiler is by default in pedantic mode (LHCb also like to use this option).
The following issues have been fixed:
- removal of unused arguments
- comparison between signed and unsigned integers
- not calling of base class copy ctor in copy ctor's
To be done, the TGeo classes where we get still many hundred warnings of
the above nature. List forwarded to Andrei.

Modify TProfile::GetBinError to disable the optimisation when the number
of bins is greater than 1000. The time of the old algorithm was proportional
to the number of bins, generating a N^2 problem when projecting a TProfile
with a large number of bins (eg 100000).

Add new function
Int_t Merge(TCollection *list)
All classes created by TTreePlayer::DrawSelect have now a Merge function.
This function will be called by the PROOF system currently in development
to merge the list of objects generated by each slave processor on
the master server.
In case of histograms (1,2,3-D, profiles) Merge computes the min/max for
the x, y or z axis, the new number of bins, if necessary. iT add bin contents,
errors and statistics.
The function returns the merged number of entries if the merge is
successfull, -1 otherwise.
In case of polymarkers (2 or 3-d), Merge adds the list of markers in
the collection to the current object.
An example to merge a list of histograms with different binning, but
having a lowest common denominator bin size is shown below:
void atest() {
TH1F *h1 = new TH1F("h1","h1",110,-110,0);
TH1F *h2 = new TH1F("h2","h2",220,0,110);
TH1F *h3 = new TH1F("h3","h3",330,-55,55);
TRandom r;
for (Int_t i=0;i<10000;i++) {
h1->Fill(r.Gaus(-55,10));
h2->Fill(r.Gaus(55,10));
h3->Fill(r.Gaus(0,10));
}
TList *list = new TList;
list->Add(h1);
list->Add(h2);
list->Add(h3);
TH1F *h = (TH1F*)h1->Clone("h");
h->Reset();
h.Merge(list);
h->Draw();

Add new functionality to the histogram package via the new functions
SetBuffer, BufferFill and BufferEmpty.
virtual void SetBuffer(Int_t buffersize, Option_t *option="");
virtual Int_t BufferFill(Axis_t x, Stat_t w); //protected
virtual Int_t BufferEmpty();
Add new members:
Int_t fBufferSize; //fBuffer size
Double_t *fBuffer; //[fBufferSize] entry buffer
When SetBuffer is called, a dynamic buffer is created to hold up to
fBufferSize entries. When the standard Fill functions are called,
the arguments are put in the buffer, if a buffer is specified.
When the number of entries in the buffer is greater than fBufferSize,
the function BufferEmpty is automatically called.
BufferEmpty will fill the histogram with the entries in the buffer.
In case one of the axis has its lower limit greater or equal
to its upper limit, BufferEmpty calls the THLimitsFinder::FindGoodLimits
to compute the axis limits based on the entries in the current buffer.
When an histogram is created with an axis lower limit greater or equal
to its upper limit, the SetBuffer is automatically called with an
argument fBufferSize equal to fgBufferSize (default value=1000).
fgBufferSize may be reset via the static function TH1::SetDefaultBufferSize.

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.
