      TGeoManager:
  - fixed a bug in Safety() introduced when inlining the method
TGeoVoxelFinder::IsSameVoxel() - I observed it just now when debugging
IsSameLocation - several daughters of a voxelized volume were not
checked resulting in an overestimated safety and in some cases wrong
snext computation (only with TGeant3)
  - fixed IsSameLocation which was resetting some parameters due to
direct calls to FindNode in case of MANY (you know, the geometry of
Alain has MANY's)
  - IsSameLocation called now only for new points x,y,z are not within
previous safety distance.
- eliminated the useless call to FindMatrixOfDaughterVolume() inside
TGeoManager::SetTopVolume() that made the visualization slower and even
produced a crash in case of very large geometries (see my today post in
the forum http://root.cern.ch/phpBB2/viewtopic.php?t=371)

      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)

      From Andrei Gheata:

some changed files in TGeo improving the performance of
TGeant3 WITHROOT:

- safety was computed twice (both by TGeoManager::Safety() as well as
the shape algorithms called by TGeoManager->FindNextBoundary()). The
speed now with WITHROOT improves.

- few fixes in some shape algorithms related to boundary treatment (few
others to be done)
- Improved computation of normals
- Improved non-recursive algorithm of TGeoPgon::DistToOut()

- fix of some default value in all shape headers (0 replaced by kBig) to
allow range limited computation of DistToIn/Out - now working just for pgon.

      - 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)

      - fix in pcon and pgon safety for points exactly on boundaries
- new class TGeoVolumeAssembly inheriting from TGeoVolume and
representing an assembly of volumes. This helps grouping togeather a set
of nodes (using the usual TGeoVolumeAssembly::AddNode()) without the
definition of a container. When positioning an assembly in other volume,
this will just position its own nodes inside this, without being
integrated to the logical hierarchy. The class is not well documented,
but a detailed description will go to the users guide.

      few modifications in TGeoMatrix class:

- few extra setters
- 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)
