 * Model scale and model offset:
 * -----------------------------
 * A 3D model is scaled by scaling its matrix.
 * The scale is computed such that is multiplies a 3D meter vector.
 * This means that a model's offset, which is defined in meters,
 * can be directly assigned to its matrix's origin.
 * Evidently, OSG must be multiplying the matrix origin by the matrix scale.
 *
 * Compressed (gzip) 3D model files can be loaded:
 * ---------------------------------------------
 * Compressed 3D models are read from a .gz file using "gzstream"
 * which is passed to osgDB::ReaderWriter::readNode(std::istream&).
 * A consequence is that OSG must be notified of all directories
 * that contains graphics assets referenced by the 3D model file.
