Primitives::BoundingVolume::syntax is "friend class" instead of "friend"
Overall:
- some fixes that make the thing compile under linux and macosx
- some wip toward a identical "high level" API which needs to be the same under tdme(java) and tdme(cpp) which does not require to use the heap at this level
