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 Andrei:
- new method TGeoShape::GetMeshNumbers() that allows getting the number of points, segments and polygons in the mesh of any shape - to be used by an upgrade of the overlap checker
- addition in the overlap checker to use the above info
- modifications in TGeoManager for improving performance for tracking geantinos with G4root interface

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 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:
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 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

From Andrei Gheata:
- TGeoHalfSpace - we needed half-spaces for FLUKA example from Alfredo,
so Mihaela implemented this shape. It can be used only as component of a
composite shape, in combination with a finite shape. Defined by:
- a point lying on the plane
- normal to the plane at this point, pointing outwards the half-space
