		assimp calls all importers in the order in which they
		are registered and each importer gets the opportunity
		to load the file until one importer "claims" the file. Apart
		from file extension checks, importers typically use
		other methods to quickly reject files (i.e. magic

		file extensions such as XML would be tediously slow. */
