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.

Fixed a side effect from previous patch: when opening macro files in
the ROOT Browser or TGTextEditor, the text was not displayed until
one moves the scrollbar, or selects the text with the mouse

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

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.

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 valeriy Onuchine:
- TImage, TASImage
o Change return type of Vectorize method from "void" to "Double_t*".
o Implement FromWindow method under X11. This method allows to
create "snapshot image" from any ROOT window or frame.
- config/Makefile.depend
Add dependency of libGuiBld lib on libGraf.
GuiBuilder uses internally TImage/TASImage class.
- GX11Gui.cxx
X11 error handler was slightly modified.
Many X11 errors lead to freezing X11 server and
did not allow debugging.
To prevent freezing, a "forced seg.violation" was added
to the error handler.
The usage of the new "feature" is the following:
0. run "gdb root.exe"
1. set "gDebug = (int)gVirtualX" - that activates the new error handling.
2. run application which has X11 errors.
On X11 error the application was stopped by the "forced seg.violation".
3. "gdb>bt" - backtrace the problem.
!!! A big list of changes in libGui initiated by gui builder development !!!
- TGButton.h, TGButton.cxx
TGButton class:
o SetDown methods removed from context menu.
o SetEnabled method of context menu changed to TOGGLE.
Setting fWidgetFlags was added.
- TGTextButton class

(normal/old usage). If "wait" is kFALSE - "gClient->WaitForUnmap"
should be called by user.
o new methods:
void SetFont(TGFont *font);
void SetColor(Pixel_t color);
void SetAlign(Int_t align);
void EnableAlign(Bool_t on = kTRUE);

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."

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" \

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 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.
