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.

Thread data is now pre-allocated when calling gGeoManager->SetMaxThreads(). This adds ~20MB for ALICE geometry per 100 threads, but avoids atomic allocations and thread locking. All run-time geometry locks removed. Thread id stored now using static thread__ allocator, faster and lock free for subsequent calls issued by the same thread.

From Andrei:
there was an implicit dependency of TGeoMatrix by TGeoManager.h via TGeoNavigator.h->TGeoCache.h + few other bad dependencies like: TGeoMatrix included by TGeoNode.h via TGeoPatternFinder.h  Hmm... I had to cleanup few inlines, introduce a transient matrix in TGeoNavigator (to recover the lost inlining speed) + add several #include "TGeoMatrix.h" allover where this was included and used via TGeoManager.h

From Andrei:
1. Possibility to export/import TGeoVolume objects in a similar way as we
can do it for TGeoManager class. Note that for the moment only the .root and
.C formats are supported (for .gdml I don't know how to do it). One can now
import several volumes from file(s) and connect them to the same TGeoManager
object:

Exporting is straightforward:
   module1->Export("file.root"); // by default file is overwritten
   module2->Export("file.root","","update"); // to the same file

Importing will append the volume to the current TGeoManager or will create
one:
   TGeoManager *geom = new TGeoManager("myGeom", "");
   TGeoVolume *top = geom->MakeBox(...);
   geom->SetTopVolume(top);
   TGeoVolume *module1 = TGeoVolume::Import("file.root", "MOD1"); //
name of volume or key (depending on export usage)
   TGeoVolume *module2 = TGeoVolume::Import("file.root", "MOD2");
   top->AddNode(module1, 1, new TGeoTranslation(0,0,100));
   top->AddNode(module2, 1, new TGeoTranslation(0,0,-100));
   geom->CloseGeometry(); // One should close himself the geometry

2. Fix in the overlap checker and functionality extension:
   TGeoVolume::CheckOverlaps(Double_t ovlp, Option_t *option)
uses now option="d" or option="d<number>" to perform overlap checking by
sampling the volume with <number> random points (default 1 mil.). It
produces also a picture showing in red the overlapping region and estimates
the volume of the overlaps.

3. TGeoMaterial class takes now as optional arguments the material state,
temperature and pressure for compatibility with GEANT4

4. Few modifications of some navigation flags needed to run correctly G4
navigation interface.

From Andrei & Mihaela:
a diff containing the implementation of TGeoShape::Capacity. There are also
few other fixes (see below):

Mihaela:

New method:
  Double_t TGeoShape::Capacity() const;
implemented for all supported shapes. The algorithms provide analytical computation of
shape capacity in [cm^3]. All algorithms are accurate with 2 exceptions:
- TGeoCtub : the formula is just an approximation due to the difficulties to integrate
over the phi angle in the general case.
- TGeoCompositeShape: the computation of the capacity is done by sampling, with an
accuracy of 1%.

Based on this method I extended the implementation of TGeoVolume::Weight(Double_t
precision, Option_t *option). The default value of option is now "va" meaning: verbose
+ analytical. Removing "a" from the default option performs computation of volume
weight using the old algorithm of sampling. I have checked the 2 ways of computing the
weight one against the other and they are consistent.

Andrei:

- fixed a memory leak related to TGeoShapeAssembly ownership
- fixed some tracking problems for assemblies (when the top volume was an assembly)

From Richard Maunder:
Major changes to GL viewer to support:

i) Logical/Physical shape pairings
ii) Level of detail (LOD) scheme (TGLSphere only using at present)
iii) Common display list cache
iv) Scene rebuilds for large geometries
v) Some basic interactivity improvements - draw timeouts, drop low LOD
shapes etc
vi) New camara interactions:

Left Mouse: Rotate
Middle Mouse: Truck (pan parallel to camera film plane)
Right Mouse: Side-side drag dolly/zoom
Double click any button to reset the camera.

The previous pan with arrow keys, and zoom on mouse wheel are still
supported.

Camera interaction is default in viewer. These extra camera modes mean
there are not enough mouse buttons for previous right context/select.
To select / invoke context menu use Shift+Left Button and Shift+Right
Button respectively.

From Mihaela Gheata:
 some additional fixes. CMS muon is now ok (some rotations in
TGeoCombiTrans were not registered)
I also fixed SavePrimitive for composite shapes - tested for csgdemo.C
(the logic there was not at all working). I hope it works also with lhcb
- if not, please send me the geometry file. There is also a fix in
TGeoXtru::SavePrimitive.

 For testing SaveAs, you should regenerate the tested geometries (not
importing the .root file generated before these changes). Otherwise some
matrices can still get wrong.

From Richard Maunder:

Changes to viewer infrastructure (TBuffer3D,TVirtualViewer3D) to
support:

i) Proper shape specific (sphere, tube, etc) descriptions in TBuffer3D
derived classes - c.f. abuse of raw tesselation blocks before.
ii) On demand filling of buffer sections as required by viewer.
iii) Support for local/master frame shapes descriptions & child object
rejection.
iv) Template/placed shapes ids - enabling viewer to detect/receive
common shapes once and just obtain the new position and id of the
duplicate.

Cleans up all producer (g3d/geom) code so no longer has an viewer
specific knowledge - Paint() methods replaced with
GetBuffer3D/FillBuffer3D methods which complete requested sections of
the buffer.

All viewer specific code now sits on the viewer implementation side of
TVirtualViewer3D. Added a TViewer3DPad class for performing the 3D draws
into pad. In future this should be merged with TView/TView3D possibly.

TBuffer3D is now stripped of functional code (aside from memory
management) and various viewer passback options there previously.
Enforced one way passing a const & to viewer.

Buffers (various types) are held as single static inside producer
function e.g. TGeoShape::GetBuffer3D (c.f. single generic buffer type
fetched from pad previously).

For g3d and geom shapes the top level geometry painter (TNode /
TGeoPainter) controlls painting process, requesting shapes to fill
buffer and passing to 3D viewer.

Exceptions are g3d's TPolyLine3D, TPolyMarker3D & TMarker3DBox. These
are 'standalone' shapes - no controlling 'painter' object. They still
implement Paint(), fill buffer and add to viewer directly.

3D viewer still held / created by pad - and pad has it's own viewer
object (TViewer3DPad).

NOTE:

1. Current scheme supports one 3D viewer only - pad, x3d or OpenGL. This
means that pad goes blank when x3d/OGL is spawned, and is updated again
when it is closed. To be revisited - need to support multiple viewers,
of multiple types - which implies explicit naming or pad controlling
enumeration.

2. OGL viewer now responds correct to modifications in pad, without
having to be reinvoked (as previously). x3d is still decoupled (as
previously) so does not rebuild - too difficult to get working.

From Mihaela Gheata;

- divisions supporting SavePrimitive
- main SavePrimitive loop implemented at level of TGeoVolume
   - user interface: TGeoVolume::SaveAs(const char *filename); having *MENU*
   - can be called from the browser for any volume:
     the resulting file will have a geometry starting with the selected
     volume as TOP.
   - should work with TPad::SavePrimitive(ofstream out, Option_t *option)
   - not tested however

From Andrei:
I did some changes in TGeoCombiTrans to support a shared rotation matrix.
I also fixed a bug in TGeoTube::GetMakeRuntimeShape (and tube segment)
that produced wrong shapes in case one of the initial parameters was negative.

From Andrei Gheata:
The diffs for the changes from Mihaela. They implement the SavePrimitive method for:
- all shapes
- materials, mixtures and media
- matrices
- TGeoVolume - just a first version

What is missing:
Divisions + manager metod to save:
- all geometry
- just the branch corresponding to one volume

The differences compared to g2root are that:
- when saving just a a branch just materials/media/matrices for that branch are created (module encapsulation)
- instead of creating objects with numerical arguments, the coresponding variables are defined and used.
 e.g. instead of :
   new TGeoBBox("name", 10.,20.,30); the generated code is:

   dx = 10.;
   dy = 20.;
   dz = 30.;
   pShape = new TGeoBBox("name", dx,dy,dz);


The diffs contain also 2 shapes with boundary-safe algorithms: TGeoPara and TGeoTrap

New shape TGeoHype from Mihaela.
This patch contains all modifications in TGeo, additions in
g2root to adjust format of MakeHype(...) and a fix in TBuffer3D.cxx
(Paint("SAME")). Also Mihaela modified geodemo.C

 The modifications (made by Timur probably) TGeoTube::Paint() for making
GL-like tubes are wrong so I temporary disabled them. The global matrix
filled to GL is wrongly retreived (+ it may come from other sources in
case of overlap drawing).

 - normal to the plane at this point, pointing outwards the half-space

visualization system to be introduced shortly).
The new mechanism is implemented in
TGeoPainter::PaintShape (uses gGeoManager as we discussed), but it also
affect some shapes (TGeoCompositeShape at least)


- New  files: TGeoElement.h /.cxx representing a chemical element. This
is very helpful for the implementation of TFluka. Materials/mixtures can
be now built also based on this new class. An element table is kept
always transient in memory.

- Mihaela implemented the TGeoParaboloid shape: new files:
TGeoParaboloid.h/cxx.

From Andrei Gheata:
I have added the possibility to create composite shapes based on
pointers to basic shapes/matrices complementary to the option based on
an expression. The advantage with the pointers
approach is that it's less error prone and easier to debug. In addition,
it avoids complications when some names are not unique.
 The procedures to create a composite shape become:

 1) TGeoCompositeShape("myShape", "(A:m1+B:m2)*C:m3")  - based on expression
 2) TGeoUnion *u = new TGeoUnion(ptrA, ptrB, ptrM1, ptrM2);
     TGeoCompositeShape *cs1 = new TGeoCompositeShape("intermediate", u);
     TGeoIntersection *i = new TGeoIntersection(cs1, ptrC, 0
/*identity*/, ptrM3);
     TGeoCompositeShape("myShape", i);

corresponding shape classes.

- New primitive shape fully implemented, from visualization to
computation of distances (except the normal computation, missing also
for several other shapes). Class name: TGeoTorus, representing a torus
segment with :

From Andrei:
- all shape classes : changed the prototype for Safety() method.
Eliminated validity checking in Divide() methods that are now globally
handled by TGeoVolume::Divide(). Added methods
TGeoShape::GetAxisName/Range(Int_t iaxis) which are used by the new
global division mechanism.
- safety for TGeoTrap now computed (pcon, pgon not yet)
- TGeoVolume : eliminated unnecesarry Divide() prototypes. The new
Divide() prototype is backwards compatible (old macros works with it)
but supports an option in order to allow all G3 division types. More
description in TGeoVolume::Divide().
- TGeoManager : Only one prototype for G3-like divisions left,
supporting all G3 options and also being able to assign to the division
volumes a medium different than the one of the divided volume. New
FindNode(x,y,z) implemented. New IsSameLocation(x,y,z) with the same
functionality as GINVOL.

Upgrade of the geom classes by Andrei:
- improvements in the drawing mechanism (nodes can also be made
invisible, having higher priority than volumes;
- possibility of simple phi cut in TGeoManager::SetPhiRange(phimin, phimax)
  - by default the phi range is (0, 360) - no cut performed
 - setting different values for phimin, phimax will make invisible the
nodes having the origin in this range;

- documentation updated for TGeoArb8 class (picture in /gif directory)

From Andrei:
 I have made a few corrections related to TGeoManager registration to
the browser and to the TGeoChecker::LegoPlot. Also a small fix in
TGeoPgon class. Change the default number of bins for lego plots.

New version of the geometry package by Andrea & Mihaela Gheata
New features:
 -I/O for all geometry classes. For example, to save/restore a geometry structure,
   TFile f("mygeom.root","recreate");
   gGeoManager->Write("mygeom");
  and to read it back;
   TFile f("mygeom.root");
   f.Get("myGeom");
   gGeoManager->CloseGeometry();

 -Composite shapes fully implemented (no visualisation yet).
  A composite shape is built out of basic shapes and transformations via
  a simple formula mechanism, eg assuming a TGeoTube "tub1" and a TGeoMatrix "r1",
  we can build a composite shape with:
    TGeoCompositeShape *comp = new TGeoCompositeShape("comp",formula); where
    char* formula="tub1+tub1:r1"
  This will create the union of a tube with itself rotated.
  The operators recognized by the geometry formula parser are "+","-","*"
  for union, subtraction and intersection respectively. The colon ":" can be
  used to specify a transformation for a given component.

 -The voxelisation in cylindrical coordinates added as an optional optimisation
  algorithm.

 -Some bug fixes and several improvements in the tracking-related algorithms.
