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.

Fix https://savannah.cern.ch/bugs/?93931.
A time axis defined with the GMT option, saved into a root file in a given time zone, was different when displayed in an other time zone. The time zone offset in which the axis was created is now saved with the time axis offset allowing to make the right adjustments when the axis is displayed in an other time zone.

the way along the axis, only between the lowest and the highest major tick.

TGaxis* a = new TGaxis(0.1,0.4,0.9,0.4, "f", 50510, "-");

- On log-scale TGAxis, with labels having lower values than 1 and ticks marks
set to the positive side, alignement issues seem to come up.
The following example shows four TGAxis drawn respectively with the
following options: RG-, RG+, LG-, LG+. For the RG+ and LG+ options,
the 10E-1 and 10E-2 labels were ill-aligned, showing a shift to the right
compared to the 1E2, 1E1 and 1 labels.

- Remove a stupid construct in PaintAxis. In the "fFunction" case there was
an if statement like:
if (optionNoopt && !optionInt) {
dxtick=(binHigh-binLow)/Double_t(nticks-1);
} else {
dxtick=(binHigh-binLow)/Double_t(nticks-1);
}
Now replaced by the simple line:
dxtick=(binHigh-binLow)/Double_t(nticks-1);
This code was like that since at least May 2000.

- To remove axis' labels ROOT's users set the LabelOffset to a large value
(very often 99). This ended up with some text drawn at very "far away"
positions. Some low level text painting functions (like the TASImage one)
were "not happy" with such big values and produced a Seg-Fault. This
problem is visible since the text clipping is done directly in TPDF and
TPostScript and not any more in TPad (TPad text clipping was wrong).
Now, if the label offset is set that way (ie "big"), the option "UnLab"
is automatically turned ON.

- From Bertrand and Olivier:
The flag tm_isdst in the "tm" structure is now set to 1 to put the
daylight saving on. We have also checked that this fix is compatible
with the fixes done in Revision 1.86 and 1.93. Also, a protection has
been added against negative timeoffset after a call to mktime (it
occurs sometimes on windows).

With:
gStyle->SetLabelFont(131,"x");
gStyle->SetLabelFont(131,"y");
the axis labels in log scale showed up without the latex markup rendered
properly. 1000 appeared as the ascii "10^{3}", not the rendered 10 with a
superscript 3.
The following little script reproduces the problem:
{
gStyle->SetLabelFont(131,"x");
gStyle->SetLabelFont(131,"y");
TH1F h("h", "h", 100, 0, 1000000);
h.SetBinContent(10, 1000000);
h.SetBinContent(50, 100);

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."

From Bertrand:
Fix a problem in TGaxis due to a special behaviour of "mktime" on Windows
If successful, *mktime* sets the values of *tm_wday* and *tm_yday* as
appropriate and sets the other components to represent the specified
calendar time, but with their values forced to the normal ranges. The final
value of *tm_mday* is not set until *tm_mon* and *tm_year* are determined.
When specifying a *tm* structure time, set the *tm_isdst* field to:
* Zero (0) to indicate that standard time is in effect.
* A value greater than 0 to indicate that daylight savings time is
in effect.
* A value less than zero to have the C run-time library code compute
whether standard time or daylight savings time is in effect.
(The C run-time library assumes the United States' rules for implementing
the calculation of Daylight Saving Time.) *tm_isdst* is a required field. If
not set, its value is undefined and the return value from *mktime* is
unpredictable. If /timeptr/ points to a *tm* structure returned by a
previous call to *asctime*, *gmtime*, or *localtime*, the *tm_isdst* field
contains the correct value.

Before it was -1. -1 meant "daylight saving time is not available". 0

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

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).

From Damir and Olivier:
Correct a few remaining problems for time axis. Now, the time stored in
the format is always expressed in UTC. The local time is calculated
only at display time if the "gmt" option of SetTimeOffset is not used.
This allows to send a plot to someone in another time zone without
discrepancies on the time displayed.
If the plot uses "gmt", it will always show the same, whatever time
zone. If not, the time displayed will be the one local to the
displaying machine.

- 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.

From Olivier:
In TGaxis and TAxis the time offset in now managed without using TDatime.
Using TDatime was not a good idea because its starting date is 1995. The
new mechanisms uses now 1970 (like UNIX) as starting date. Note that the
functionality and examples given in the HowTo page and documentation
remains exactly the same.

From Olivier:
It is now possible to set a time offset equal to zero for time axis. When
the time offset is zero, the axis limits are considered as absolute times.
The following example shows how it works:
{
TDatime T1(1998,01,05,00,00,00); // First date
int X1 = T1.Convert();
TDatime T2(2002,12,31,00,00,00); // Second date
int X2 = T2.Convert();
TH1D *iT = new TH1D("iT","time axis",1000,X1,X2);
iT->GetXaxis()->SetTimeDisplay(1);
iT->GetXaxis()->SetTimeFormat("%d\.%m\.%y");
iT->GetXaxis()->SetTimeOffset(0);
iT->GetXaxis()->SetLabelSize( 0.03 );
iT->Draw();
}

Implement extension of TLatex by Damir Buskulic.
A TLatex string may be split in two lines (like a fraction without the line)
with the new command #splitline{top}{bottom}.
TAxis and TGaxis have been modified to take advantage of the new feature.
For example a new option in the time axis can show the date/time over two lines
with eg: #splitline{21 April 2003}{14:23:56}

Add a new optional argument drawGridOnly to TGaxis::PaintAxis.
By default, this argument is false. If set to true, the function PaintAxis
paints only the grid (if gridx or/and y have been activated in the pad)

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.

Add a new member function TGaxis::SetNoExponent to disable the notation
with 10^N when drawing the axis. This option is automatically selected
when drawing TAxis objects having this property.
Note that this option is implicitly selected if the number of digits
to draw a label is less than the fgMaxDigits global member.

Add a static member fgMaxDigits with the corresponding getter and setter.
fgMaxDigits is the maximum number of digits permitted for the axis
labels above which the notation with 10^N is used.
For example, to accept 6 digits number like 900000 on an axis
call TGaxis::SetMaxDigits(6). The default value is 5.

Change the maximum authorized exponent from 30 to 200 in TGaxis::Optimize.
This change allows drawing axis with the maximum precision in case of very large
or very small values.
The change was also necessary to avoid a buffer overflow in the function
drawing labels.

Add the following missing description of option "S" in TGaxis::PaintAxis
// Size of tick marks
// ------------------
// By default, tick marks have a length equal to 3 per cent of the
// axis length.
// When the option "S" is specified, the length of the tick marks
// is equal to fTickSize*axis_length, where fTickSize may be set
// via TGaxis::SetTickSize.

// 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;
