// I (Nikolaus Gebhardt) did some few changes to Jonas Petersen's original loader:
// - removed setTexturePath() and replaced with the ISceneManager::getStringParameter()-stuff.
// - added EAMT_LMTS enumeration value
// Thanks a lot to Jonas Petersen for his work
// on this and that he gave me his permission to add it into Irrlicht.
