- Further work on IFC, fix transformations, support non-uniform transformations, optimize loading, use recursive algorithm to resolve holes in polygons, implement CSG logic to generate wall openings. The latter is currently disabled.

- IFC: implement automatic conversion from polygons with holes to polygons that consist of only one piece and are thus applicable to triangulation by ear-cutting. This solves many of the broken windows that would fall victim to z-fighting in earlier revisions.

- IFC: directly keep a pointer to the class name in STEP::Object. This avoid hacking around with typeid().name(), which yields platform-dependent results.
