added pretransformvertices postprocess step bugfixes in the 3ds material system. transparency is now displayed correctly Node view in the viewer display the local transformation matrix now Fixed wrong directory name. "unused" renamed to "extra" ---> all is WIP ... git-svn-id: https://assimp.svn.sourceforge.net/svnroot/assimp/trunk@50 67173fc5-114c-0410-ac8e-9d2fd5bffc1f
