- Store shapes in std::vectors rather than TopoDS_Compounds - Apply transformation only on triangulated meshes or when processing openings - Store transformations in a gp_GTrsf to allow arbitrary transformations - Support IfcCartesianTransformationOperator3DnonUniform - TODO: Create proper class for ShapeList - TODO: Carefully check for null pointers returned from IfcGeom::convert_shape()
