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 Bertrand:
Added drag and drop support for Linux (Xdnd) and Windows (Clipboard).
It is now possible to drag an histogram (or any other graphical object)
from an opened file in TBrowser to any TCanvas.
It is also possible to drag a text file from TBrowser to a TGTextView
or TGTextEdit widget (i.e. in TGTextEditor).
On Linux, it is even possible to drag from a Root application to another
one, or to drag a text file (i.e. a macro) from the ROOT browser to an
external editor (i.e. Kate).
On Windows, drag and drop only works within the same ROOT application
(for the time being).

From Valeriy Onuchin:
TGView, TGTextView, TGTextEdit classes
The main changes :
o restructuring and revisiting the code
- move all text methods from TGView to TGTextView class.
o new methods
TGTextEdit::SetSelectBack - setting selection background color
TGTextEdit::SetSelectfore - setting color for slected text
TGText::AsString - return content as ROOT string.
o improved painting: exposed events, resizing
- compression of exposed events added which
eliminates flickering when text_edit widget is resized or
exposed.
- repaint only whose areas which where modified or
overlapped.
o undo management on Ctrl-Z
o autoscrolling when text is selected
o many small bug fixes:
- crash on double click on blank field
- selected text in some cases was not correctly removed
- etc.

Instead of providing default implementations for copy ctor's and assignment
operators we better make them private (and not implemented) to avoid people
from accidentally using them. Especially the collections classes and the
TQObject derived classes. In these classes the default implementations would
cause havoc due to multiple deletions of the same objects and other
potential memory corruptions.

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 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 Valeriy Onuchin:
- provide default constructors for most TGxxx classes.
The goal:
1. required for guibuilder
2. providing ROOT I/O for GUI classes.
In all default constructors parent window is NULL,
that means that parent window is currently editted window.

Add new functions suggested by Maxim Nikulin
"I use TGTextView widgets in my monitor program. Several thousands calls
of the AddLine() method make the program extremely slow. Using the
callgrind program I found that the AddLine() is most expensive in my
case because of Layout() invocations.
I suggest add methods AddLineFast() and Update(). Together they do the
same work to AddLine(), but it becomes possible to invoke AddLineFast()
many times and call the slow Update() method only once.

major changes in the resource management of the GUI classes. Introduced the
new class TGResourcePool which loads and keeps track of the 3 main resource
pools: fonts, picture and graphics contexts. Fonts are now handled via the
new TGFont class (and TGFontPool). In the past the loading of these resources
was done in TGClient and required all GUI classes to have TGClient as friend
to have their global statics initialized by TGClient. Adding a new widget
required TGClient.cxx to be changed too. This was obviously not good.
In addition it is now possible to find the full definition of the original
resource back based on a resource handle (GContext_t or FontStruct_t yielding
a TGGC or TGFont) which is needed for the SavePrimitive() functionality.
The resource pool can be found via TGClient (e.g. gClient->GetResourcePool()).
To see all active graphics contexts, fonts and pictures do:
gClient->GetResourcePool()->GetGCPool()->Print()
gClient->GetResourcePool()->GetFontPool()->Print()
gClient->GetResourcePool()->GetPicturePool()->Print()
For more examples see the widget source code.
These changes are largely backward compatible except maybe for some low
level 3rd party widgets that use some TGFrame internals. In these cases
the following sed command will patch the code:
sed -e "s/fgBlackGC()/GetBlackGC()()/g" \
-e "s/fgWhiteGC()/GetWhiteGC()()/g" \
-e "s/fgHilightGC()/GetHilightGC()()/g" \
-e "s/fgShadowGC()/GetShadowGC()()/g" \
-e "s/fgBckgndGC()/GetBckgndGC()()/g" \
widget.cxx > widget.cxx.new

changed inheritance tree. Move TQObject inheritance from TGWidget to
TGFrame. This allows all frames to emit signals (all widgets were frames,
but not all frames were widgets). Added several missing signals in several
different widgets to get tutorials/guitest.C working.

many change connected with the introduction of the TGGC (graphics context)
class (all backward compatible). Also many of the static default GC's and
fontstructs are now available to the user. This can simplify code in many
places. See change in guitest.cxx.

many improvements and fixes in the text edit widget. Fully implemented
cut/copy/paste between editor and any X11 window supporting text (and
vice versa). Also added a context menu giving access to the most essential
text editor actions (open, close, save, print, search, etc.). Fixed several
text navigation and selection issues.

infrastructure for the new TGTextEdit widget. The new TGView class is
the base class for all text viewing/editing widgets. TGTextView has been
totally rewritten to use the new TGView and TGText classes. TRootHelpDialog
uses the new TGTextView widget. TGTextEdit will derive from TGTextView.
