Added possibility to prevent known overlaps produced by misalignment by assignig priority to one of the candidates. This is not using the error prone AddNodeOverlap method, but composite shapes. One has to create the unprioritized shape as the subtraction of the original one and the shape of the node to prioritize, then position this composite shape colume with identity matrix. The prioritized volume should be added as node using the same local matrix as the one used in the subtraction operation. The matrix itself has to be declared shared via SetShared() method. Added few parameters to the RandomRays method.

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 Artur Szostak:
There is a mechanism in GCC 4.6.0 that will allow one to effectively prevent the false positive warnings for -Weffc++ from appearing in software that builds against ROOT, with the -Weffc++ flag set, such as AliRoot. I propose using the mechanism, which will make the development in AliRoot much more pleasant.

Set property svn:eol-style LF on all source and Makefiles. This should avoid
problems with Win32 line endings ending up in the repository. All MS tools
support LF eols fine.

From Andrei:
a big chunk of modifications that mainly allow converting a geometry
containing reflection matrices into a reflection-free one.
This is done via a mechanism implemented in TGeoManager/TGeoVolume/TGeoScaledShape
classes which can be invoked using:
TGeoManager::ConvertReflections() method once the geometry is closed.
This is required for normal GEANT4 operation and is to be used only
in G4 navigation context.

Besides that, I made some changes which allow now controlling visibility
of nodes/volumes directly from the TBrowser (check-boxes).
This was not really working before.

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:
few modifications including a fix to a serious problem: in my last patch
for TGeoPatternFinder.cxx class I removed by mistake a line resulting in the fact that
no division on Z axis is seen anymore by tracking!!


Few other modifications:
- TGeoManager::Edit() to invoke the geometry builder plugin if existing (Mihaela)
- few fixes in the painter for the case when the geometry is not closed
- a small correction in TGeoManager related to MANY's

From Andrei:
new class TGeoScaledShape + the modifications
needed to compile it. There are also some minor fixes.

A scaled shape can be any basic or composite shape for which you
apply a scaling transformation. If a volume has a scaled shape it
does not imply that its nodes are scaled (the scale applies ONLY
to the shape itself). To define a scaled shape:

  TGeoShape *non_scaled = ...; // define a shape
  TGeoScale *scale = new TGeoScale(sx,sy,sz);
    // sx,sy,sz are scaling factors on each axis (non-zero)
  TGeoShape *scaled_shape = new TGeoScaledShape(non_scaled, scale);
   // the scaled shape is ready to use

From Andrei:
a small change in TGeoRotation needed by Cvetan. It is backward compatible
and adds extra functionality to TGeoRotation::GetPhiRotation(Bool_t fixX=kFALSE)

The meaning of fixX is:

- if the rotation is a pure Z rotation, fixX does not matter;
- fixX = true: result is the phi angle of the projection of the rotated X axis in the
un-rotated XY
- fixX = false: result is the phi angle of the projection of the rotated Y axis - 90
degrees

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

According to Ivana's observations/patch, RotateX,Y,Z methods of TGeoMatrix derived classes
perform the corresponding rotations with respect with the master frame. Works now for
TGeoTranslation, TGeoRotation, TGeoCombiTrans and TGeoHMatrix.

From Andrei Gheata;
- assignment operators and ctors(const TGeoMatrix&) for all
transformation types; any type can be assigned to another
  ex: TGeoRotation r("name", 10,20,30);
        TGeoHMatrix h = r;   (h(r) also works)
        TGeoCombiTrans c = h; (c(h) also)
- strict checking of IsTranslation() and IsRotation() used to optimize
TGeoHMatrix::LocalToMaster/MasterToLocal which is heavily used by
navigation (was not really the case before)

- operator == at the level of TGeoMatrix class. Some limitations due to:
  rot * rot.Inverse() != identity      due to arithmetic errors (1E-14)-
the IsRotation() flag for the result remains set. Could be fixed by a
checking procedure but this would be too much time consuming. Therefore
== is guaranteed to work only after assignment/copy operations.

From Andrei Gheata:
I took a look to the way a rotation is
interpreted from Euler angles and I found that the computation of matrix
elements is not as it supposed to be, resulting in a confusing violation
of the documented convention.
  This is why I fixed it (putting also in the computation of the inverse
matrix)
  I touched also TGeoManager.cxx, fixing a warning (variable not used)

- new methods RotateX/Y/Z()
- a source of memory leaks in TGeoCombiTrans eliminated (the rotation
component is now owned by the class, it can only be copied from other
rotation)

From Andrei Gheata:
- computation of normals to all primitive shapes, except TGeoCompositeShape
- improved TGeoTorus algorithms
- ray tracing feature : works as TGeoVolume::Draw() except that the
volume is ray-traced according to current visualization settings. All
features from a normal drawing are preserved : picking, zooming,
rotating,... The time for producing the ray-traced image scales with the
surface of the current pad (in pixels) and to the number of visible
nodes on screen. The current image can be clipped with any other shape,
defined in the reference frame of the current drawn volume. It works like:
    TGeoTubeSeg *clip = new TGeoTubeSeg(params...);
    gGeoManager->SetClippingShape(clip);
    someVolume->Raytrace();
    ...
    gGeoManager->SetClipping(kFALSE/kTRUE); to disable/enable clipping.
  If the clipping shape is changed, the old one is automatically deleted.

New version of the geometry package from Andrei:

4 new files:
  geom/inc/TVirtualGeoTrack.h
  geom/src/TVirtualGeoTrack.cxx
  geompainter/inc/TGeoTrack.h
  geompainter/src/TGeoTrack.cxx

This new version adds support for track visualization. Adding tracks is a user task
and can be done using :
  TGeoManager::AddTrack() for primary tracks. The manager class knows
about the current primary and provides utility methods to
retreive/change this. Users has to handle only TVirtualGeoTracks.
Secondaries can be added to their primary :
  TVirtualGeoTrack::AddDaughter()
Points (x,y,z,tof) can be associated with a track :
  TVirtualGeoTrack::AddPoint()

  Providing tracks to the modeller and adding points are users tasks.
Track names should be supplied by users after creation :
    TVirtualGeoTrack::SetName() - note that tracks are not tnamed
objects, but their names are globally handled by the TGeoManager. The
usage of ROOT default particle names are recommended for tracks since it
triggers special colors/line attributes.
Tracks are drawable/pickable objects. Drawing options are :
  - default - only current track drawn
  - /D      - track and first level daughters
  - /*      - track and all descendents
  - /N<name> - only tracks from particles with given <name>

If points with time of flight are supplied, the drawing range tmin,tmax
can be specified :
  TGeoManager::SetTminTmax() (if no arguments time cut is supressed)

Tracks can be animated individually or global :
  TVirtualGeoTrack::AnimateTrack(tmin,tmax,nframes,option)
  TGeoManager::AnimateTrack(tmin,tmax,nframes,option)

Animation otions are :
  /G - animate also geometry in the given time interval
  /S - save all frames as .gif files
  drawing options act as well in animation. Options can be concatenated
and should be upper case (due to /N<name>)

If tracks are defined, the geometry I/O takes them into account.
However, when loading a geometry file containing tracks, libGeomPainter
has to be loaded since it contains the class implementation definition :
    gSystem->Load("libGeom")
    gSystem->Load("libGeomPainter")
    TGeoManager::Import("mygeom.root")

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.
