0028361: Visualization, TKV3d - buggy behavior of Transformation Persistence compiled on several Linux platforms in optimized mode

Browse Source 
The patch fixes transformation persistence for various set of GCC compilers.
1) Optimized template-specialized operator /= for division (causes bugs)
   of NCollection_Vec4 was replaced with non-specialized version.
2) NCollection_Vec4::xyz() is not used since compiler uses modifiable-reference
   returning version, which invokes warning of possible strict-aliasing rules
   violation and leads to incorrect behavior of the reference.
