From Andrei:
- Fix in twisted ARB8 DistFromInside/Outside algorithms which now take into account boundary errors.
- Added a check for malformed polygon definition for ARB8 and XTRU shapes which may have non-consecutive segments that are crossing each other.

From Andrei:
- TGeoXtru shapes with polygone vertices defined counter-clockwise in XY
plane were not valid (Andreas) - fixed
- TGeoVolume::SaveAs() works now correctly even in case of assemblies
(Ivana) - fixed by Mihaela
- Some minor precision problems fixed in divisions
- minor fix in navigation in assemblies; assemblies defined as overlapping
now forbidden
- fix for automatic re-voxelization after un-alignment

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)

New utility class IGeoPolygon from Mihaela Gheata:
It is able to locate if a point is inside/outside an arbitrary polygon,
defined by vertices in the XY plane - possibly scaled/translated. It
will be used by the class TGeoXtru (extruded polygon) to come soon.
