assimp/tools/assimp_view/assimp_view.cpp
aramis_acg 3f369342d6 - Redesign the C interface to allow per-import settings. 
- Make C-API threadsafe even without boost (no longer a global importer <-> scene map).
- Cleanup headers.
- Change the way how Importer::pimpl is accessed - all users are no longer friends of Importer to avoid spoiling the public interface. Rather, pimpl is exposed via a public member function and anyone having the definition of ImporterPimpl can access it.

THIS IS A BREAKING API CHANGE for anyone using properties with the C API. It is, however, a huge step forward and finally makes our C API functionally equivalent to the C++ interface.

I hope we can adapt all ports as soon as possible. I'd be grateful if the respective maintainers could do this.

Documentation is not yet up to date.

All this is in anticipation to the upcoming 3.0 release, which I'm actively working on.
