Modification for different popups: with cocoa I can not guarantee the stack order for borderless popup window
(it's "main" window can in some cases become main and key window and overlay popup).
With transient hint (which makes a popup window into a children of some other window) the problem is fixed,
now GUI does not fall to pieces at any unexpected user action.

Fix for a combobox. The problem is quite subtle and tough - with Cocoa I have to
process "paint events" immediately, but ROOT also can draw outside of paint event.
And with combobox there are 2 "rendering passes", one is with incorrect sizes, the second one
is with correct sizes. With X11/Win32 these passes are sequenced - and the second
one is initiated by expose event. With Cocoa the second pass actually happens before the
first one. This, plus some implementation details and different event order results
in quite ugly visual artefact - the button in the right part of combobox is
not correctly repainted.

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 a weird behavior in combo boxes: When the mouse button was pressed on the scrollbar of the combobox popup, and then released outside, the "dragging" flag was not released, and the scrollbar element was following the mouse move events (as if it was grabbed). Thanks Timur for pointing out this oddity.

From Mattias Ellert:
If the TGFontTypeComboBox constructor detects that the requested X11 font is not installed and falls back to TGTextLBEntry::GetDefaultFontStruct(), then the destructor must not call gVirtualX->DeleteFont() on this font.
The current version lacks protection for this which leads crashes when the default font struct is used after it has been wrongfully deleted by the TGFontTypeComboBox destructor. The backtrace generated can piont anywhere where the default font struct is used, but there is also an error message that says:
Root > Error in <RootX11ErrorHandler>: BadFont (invalid Font parameter) (XID: 71303382, XREQ: 46)

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);

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.

From Valeriy Onuchin:
- TGWindow
o kEditDisableBtnEnable - bit intoduced, which says
"window cannot be edited but can handle mouse button events".
Typical usage is buttons in complex widgets like
buttons in scroll bar, tab elements in TGTab etc.
- TGFrame
o SetBgndColor(const char *hexvalue) method is introduced.
This method allows to set frame background color as
hexvalue e.g. "#0c0c0c", or by color name "white", "blue" etc.
This method was added to guibuilder context menu.
- TGCompositeFrame
o TGLayoutManager *GetLayoutManager() const.
void SetLayoutManager(TGLayoutManager *l) made virtual.

From Daniel Sigg and Ilka:
TGTab was setting the input mask for button press for its entire window.
This then interferes with combo boxes that are located inside a TGTab
and makes it that none of the mouse clicks outside the pop-up are sent
to the combo box. This is particular annoying if you have a tabbed
application.

From Valeriy Onuchin:
- new concept of "pseudo-window" introduced.
pseudo-window - is an object inherited from TGWindow which
is not created by window system (X11 or M$ Windows).
It does not consume window system resouces.
The main use-case of pseudo-windows is GUI containers
with very large number of items. For example, listviews, listboxes,
where listview/listbox items/entries are pseudo-windows.
Pseudo-window has "window id" equal to zero.
In order to "activate pseudo-window concept" the parent should
have fIsMapSubwindows dat member to be kFALSE.
So, it's backward compatible, setting fIsMapSubwindows=kTRUE in parent window
will activate normal behavior, i.e. will be created in window system.
Introduction of "pseudo-window concept" forced the changes in
TGX11, TGWin32 classes to avoid TVirtualX methods execution when
"window id" is NULL (the case of pseudo-window).
Introduction of pseudo-windows which do not consume window system resouces
greately improved performance of TGListView, TGListBox, TGComboBox objects.
Now it's possible to have these containers with more than 10000 items.
- some optimization in TGLBContainer drawing
- add SetWindowName to most GUI classes. It's very usefull for GUI debugging.

The following mega patch is from Ilka. She has integrated and further
developed the original classes from Marek Biskup (summer student last year)..
Valeriy Onuchin has also contributed by extending/adapting existing
GUI classes.
Very first prototype of the new pad editor is available for testing and
feedbacks. It was started by Marek Biskup as his project during the
Summer Student Program 2003.
The new pad editor helps ROOT GUI to become closer to the well known
application GUIs; to be user friendly, having easier and faster access
to the ROOT graphics, to be more intuitive. It is embedded in the
TCanvas window every canvas has an editor.
The editor frame is on the left side of the canvas window. The user can
show it via Edit/Editor menu selection. The editor frame contains a set
of picture buttons for selecting well known graphical primitives for
drawing; below them there are widgets for attribute changing. When an
object is selected its name appears with a set of options available for
changing: fill style and color; line style, width and color; text font,
size and style; marker style, size and color.
New Classes:
TGFontTypeComboBox - a combo box with fonts for a choice;
TGLineWidthComboBox - a combo box with line widths;
TGLineWidthLBEntry - list box entry for different line widths
TGLineStyleComboBox - a combo box with line styles;
TGLineStyleLBEntry - list box entry for a line style
TGedEditor - the new editor containing tool-box and attribute frames of
the selected object;
TGedToolBox - frame with picture buttons for a primitive drawing
TGedAttFrame - a base class for all attribute frames
TGedAttNameFrame - a frame showing the selected object name (if exists)
TGedAttFillFrame - a frame showing the fill attributes
TGedAttLineFrame - a frame showing the line attributes
TGedAttTextFrame - a frame showing the text attributes
TGedAttMarkerFrame - a frame showing the marker attributes
TGedPatternFrame - popup window for fill pattern selection
TGedPatternSelector - a button for pattern selection
TGedSelect - service class for selecting
TGedPopup - service class for popup attribute window
TGPatternSelect - a button for selected pattern
TGedMarkerPopup - popup window for marker selection
TGedMarkerSelect - a button for selected marker
Several changes are made in TCanvas, TPad, TRootCanvas to adapt them for
the new GUI interface. The old GUI interface is kept and it can be used
too. The class TPadEditorOld provides its functionality.

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.

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" \
