The value of TBasket:;fBasket was incorrect in some cases when using
the TTreeCloner. This is solved (and thread safetly is improved) by
removing the gBranch global variable and using alternative mechanism
to set TBakset::fBasket.

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.

// 29 May
- Add the following note in the TPave, TPaveLabel and TPaveText constructors:
IMPORTANT NOTE:
Because TPave objects (and objects deriving from TPave) have their
master coordinate system in NDC, one cannot use the TBox functions
SetX1,SetY1,SetX2,SetY2 to change the corner coordinates. One should use
instead SetX1NDC, SetY1NDC, SetX2NDC, SetY2NDC.
28 May
- Modify THistPainter::PaintStat and PaintStat2 to use the TLatex character #pm
instead of +-
// 27 May
- Add new member functions:
Int_t TVirtualTreePlayer::GetDimension()
Int_t TTreePlayer::GetDimension()
GetDimension returns the number of dimensions in the TTree::Draw expression.
- Add new function in TTree;
void TTree::UnbinnedFit(const char *funcname ,const char *varexp, const char *selection="",Option_t *option=""
,Int_t nentries=1000000000, Int_t firstentry=0);
This function (origin Stephen Bailey) performs an unbinned fit to the
variable(s) given in varexp.
- Remove unused data member fDimension from class TTree.
- Introduce support for "Virtuality" in TLeafObject.
New data member fVirtual added and corresponding IsVirtual/SetVirtual functions.
By default, fVirtual is kTRUE.
This change allows new interesting possibilities in split mode. For example
if a member is TShape *fShape, a real object may be now of any type
derived from TShape (eg, TTUBE, TBRIK, etc).
With the previous version, the fShape object had to be of the declared
type TShape only.
When writing a TLeafObject, the class name of the object is now written in
the branch buffer by TLeafObject::FillBasket. When TLeafObject::ReadBasket
is called, an instance of the real class is built and its Streamer function
called.
This change is backward compatible. Old files can still be processed.
It is possible to set the virtuality for the branch to kFALSE via
TLeafObject::SetVirtual. Setting the virtuality to kFALSE makes
writing and reading faster and the file slightly smaller. In this case,
a TLeafObject must be of the type declared only.
- New minor changes in TGaxis (Damir Buskulic) for date/time format
in case the start time is not an integer value.
- Modify tutorial psexam.C to set the TPaveText TextFont to 61 instead of 62.
Font precision 1 bypass the TLatex logic.
- Mods in TLatex to remove the special treatment for characters ' and ".
Strings like l'#acute{e}toile are now correctly processed.
- Fix a bug in TGraph::GetFunction. (thanks Damon Spayde). The test
if (fFunctions) return 0; replaced by
if (!fFunctions) return 0;
