<T extends AbstractSystemLayer> T	createSystemLayer(LayerContainer lc, java.lang.Class<T> layerType) Creates a new system layer.
TimelineObjectLayer	createTimelineLayer(LayerContainer lc, ILayer layer) Creates a new timeline object layer to be used for rendering timeline objects.
static ILayerFactory	getInstance() Returns a factory.
