through display list building. The old `flow_origin` concept was ill-defined (sometimes the border box plus the flow origin, sometimes including horizontal margins and sometimes not, sometimes including relative position and sometimes not), leading to brittleness and test failures. This commit reworks the logic to always pass border box origins in during display list building.
