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 Bertrand:
As on Windows, GetFreeSpace is defined as the following macro:
#define GetFreeSpace(w) (0x100000L)
It has to be undefined in TGeoCache.h
(compilation of ROOT Event Viewer (REVE) dictionary fails on Windows)

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."

From Andrei:
a rather big patch containing a fix for the sphere mesh from Mihaela
as well as several other small fixes related to navigation + new methods. Before
doing it I included your code checker-related changes.
Mihaela:
- all sphere types (according rmin,rmax,theta1,theta2,phi1,phi2) have now the
minimum needed set of points/segments/polygons. For instance, the spheres with
rmin=0 does not have anymore the mesh for the inner sphere. Also, if there is no
phi segmentation, you do not have anymore the polygons related to the phi
slices.
- ongoing work for the same for cones (not in this patch)
Andrei:
- memory leak in TGeoPhysicalNode::Align() (hopefully) fixed. Original (ideal)
matrix now kept.
- several fixes in TGeoManager::Safety, TGeoManager::SearchNode for properly
checking all extrusions types MANY->ONLY or ONLY->MANY for all current branch.
- fix for overlapping flag bookkeeping when moving up from a divided node. The
number of MANY's in the current branch is now kept as data member of
TGeoManager. Changes in TGeoCache according to this
- Prototype for TGeoManager::FindNextDaughterBoundary() changed to return
crossed daughter index
- new method TGeoManager::FindNextBoundaryAndStep() that in addition to
computing the distance to next boundary propagates current point and finds the
new location. Changes in the raytracing algorithm to use this - seem to work
properly, but I still have to double-check some geometries.

From Andrei Gheata:
- Bug in TGeoCache.cxx affecting the current global matrix branch when
doing Push/Pop (extremely severe - VMC list should be notified to update
TGeo !)
- Minor bug fix affecting TGeoManager::FindNormalFast()
New development - not yet fully completed - TGeoHelix class. Quoting
from TGeoHelix.cxx:
// A helix provides:
// - propagation to a given Z position (in global frame)
// Double_t *point = TGeoHelix::PropagateToZ(Double_t z);
// - propagation to an arbitrary plane, returning also the new point
// - propagation in a geometry until the next crossed surface
// - computation of the total track length along a helix

From Andrei Gheata
- TGeoPgon::DistToIn() - new algorithm 50-200% faster than the old one
(depending on the number of edges) fixing the existing pgon problems
- TGeoPgon::ComputeNormal() - corrected a wrong sign
- TGeoManager::Safety() corrected in case of MANY geometries
- Bug fix raytracing + a minor fix in the calling sequence (now there is
a similar behavior of TGeoVolume:Raytrace/Draw)

add a second argument to TGeoManager::GetBranchNumbers to also return the
volume serial numbers in addition to the volume copy numbers.
Add a new data member fNumber in TGeoVolume. fNumber is the volume
serial number in the list of volumes as returned by AddVolume.

From Andrei:
attached the last version, with bug fixes in tracking. Now you can do
lego plots for everything in alice. It does not do extra steps (except
very seldom in ITS in som very thin tubes - 1 extra step to cross). Much
more stable. I temporarly disabled TGeoVolume::CheckGeometry from the
context menu of volumes since it seems to have a bug that I need to fix.
Much better version in computing distances.

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.
