org.jfree.layouting.renderer.model.NormalFlowRenderBox
A box that defines its own normal flow. All absolutly positioned or floating elements define their own normal flow. Each flow contains an invisible place-holder element, which marks the position of that element in the parent's normal-flow. A flow may hold a set of sub-flows. Sub-Flows are derived from floating elements. Absolutely positioned elements are placed on the page context. Normal-flows are derived for each absolutly or staticly positioned element. @author Thomas Morgner
