Exports an object and its children to the specified file format. NOTE: its best to only export after at least one renderpass (all object-internals like rotation-matrices etc. will then be initialized).
parameter: object The object to export. Supported: DisplayObject3D, SceneObject3D.
parameter: exportFileFormat The file export format. @see org.papervision3d.core.io.exporters.ExportFileFormat
returns: ByteArray
