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 Timur:
MacOS X native Cocoa/Quartz based backend. To build this version do:
./configure --enable-cocoa
Code is still rough but will be refined quickly for the May release.

Implement two new static functions in TColor
Int_t TColor::GetColorBright(Int_t n)
// Static function: Returns the bright color number corresponding to n
// If the TColor object does not exist, it is created.
// The convention is that the bright color nb = n+150
Int_t TColor::GetColorDark(Int_t n)
// Static function: Returns the dark color number corresponding to n
// If the TColor object does not exist, it is created.
// The convention is that the dark color nd = n+100

-Move the following functions from TStyle to TColor
static Int_t CreateGradientColorTable(UInt_t Number, Double_t* Length,
Double_t* Red, Double_t* Green, Double_t* Blue, UInt_t NColors);
static Int_t GetColorPalette(Int_t i);
static Int_t GetNumberOfColors();
static void SetPalette(Int_t ncolors, Int_t *colors);
-Move the data member fPalette previously in TStyle as a static member of TColor.
-In TColor::InitializeColors, add the call to TColor::CreateColorWheel
to create all the ROOT ColorWheel colors.

from Axel:
Change the signature of SavePrimitive from
void SavePrimitive(ofstream &out, Option_t *option);
to
void SavePrimitive(ostream &out, Option_t *option = "");
With this change one can do, eg
myhist.SavePrimitive(std::cout);
WARNING: do rm -f tree/src/*.o

From Axel:
Patch to set a canvas in grayscale mode (default is color).
New functions in TCanvas and TColor
void TCanvas::SetGrayscale(Bool_t set /*= kTRUE*/)
Set whether this canvas should be painted in grayscale, and re-paint
it if necessary.
One can toggle between a grayscale preview and the regular
colored mode using TColor::SetGrayscale(). Note that in grayscale mode,
access via RGB will return grayscale values according to ITU
standards (and close to b&w printer grayscales), while access via
HLS returns de-saturated grayscales.
TCanvas::SetGrayScale is available via the TCanvas context menu.

We added a new member fAlpha in TColor, but the ClassDef was not changed.
This problem was detected in the auto schema evolution tests for x.root
and x.xml files that we are currently running with Sergei Linev.

From Valeriy Onuchin:
- massive update of TImage/TASImage class.
- update rose_image.C macro to demonstrate new features.
- new example hist2image.C added
I'll try to add more example and documentation asap.
- bug fixes in ROOT gui builder
- TGToolBar, TGShutter now "compatible" with hierarchical cleaning
- mods in TGPicture allow create masked pictures from images.

From Ilka:
code for saving any user
specified color via color widgets in a macro. Any color different from
the standard root colors is saved via hex rgb string. Up to now colors
were save via the index and if this index > 228 the running macro causes
SegV.
A new static method SaveColor() is added in TColor class.

From Ilka:
Any ROOT GUI can now be saved as a macro. Executing this macro brings back
the current GUI (minus the action handling). This very important development
allows to get easily the source for any GUI, which can then be inspected or
used to create other GUI's. Also this will allow a GUI builder to save and
restore GUI's.
To save the source of a GUI use the methods TGMainFrame::SaveSource() or
TGTransientFrame::SaveSource(), where the latter saves the source for dialogs.
To trigger the saving of any GUI just use ctrl-s.

new method GetPixel() and static method Number2Pixel(). Use these methods
to get the pixel value associated with the TColor. This pixel value can
be directly used in the TGxxx GUI classes. For example:
TCanvas *c = new TCanvas;
widget->ChangeBackground(TColor::Number2Pixel(c->GetFillColor()));

added three new static methods:
TColor::GetColor(Int_t r, Int_t g, Int_t b) with r,g,b in range [0,255]
TColor::GetColor(Float_t r, Float_t g, Float_t b) with r,g,b in range [0,1]
TColor::GetColor(const char *hexcolor) with hexcolor of form "#rrggbb"
these methods try to find the color with the specified rgb value in the
list of existing colors, if the color does not exist it will create a
new TColor with the name "#rrggbb", add it to the global list of colors
and return the color number.
Also made the methods HLStoRGB() and RGBtoHLS() static.

delay the calling of XAllocColor() for systems with >8 planes, also optimize
the number of times XAllocColor() is called for the _dark and _light colors.
XAllocColor() is very expensive since it waits for an answer from the X server
before returning. This optimization reduces the startup time of root.exe from
30sec to 10sec over a 64Kbps ISDN line.

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.
This form allows you to request diffs between any two revisions of this file.
