 				Part of the export process. This method is run first, before all other parts of the export process.
 				The return value is used to determine if this [GLTFDocumentExtension] instance should be used for exporting a given GLTF file. If [constant OK], the export will use this [GLTFDocumentExtension] instance. If not overridden, [constant OK] is returned.
