From Jan Peciva, "I am sending improved version of Inventor plugin. Attaching just

modified files, while GroupSoLOD.h and .cpp was deleted. Please, delete
it from repository, it is not used any longer and I doubt if it is
probably not used for anything meaningful for a while. In the new code,
there is no GroupSoLOD. Please, delete it.

I am using new plugin version for about 1.5 month so I consider it
stable by myself.

List of changes:
- rewritten Inventor state stack
- shaders support
- light attenuation support
- support for reading from stream (readNode(std::istream& fin, options))
- improved grouping node handling (SoSeparator, SoGroup,...)
- fixed transformation bug when two SoShapes/Drawables with different transformations are placed bellow one grouping node
- introduced preprocessing to handle more advanced usage schemes of SoLOD and SoSwitch nodes
- unused code clean up
- improved notify messages
- animation callbacks fixes
- FindInventor.cmake improved finding routines, support for Coin3 and Coin4"
