Followup from bug 379090 comment 5: David Baron [:dbaron] 2007-04-28 18:53:23 PDT I think the long term thing to do here is make all the things that don't require a rendering context not take a layout state argument at all. Doing that probably isn't too hard -- we'd just need to split Redraw into a version not taking a layout state and one that takes a layout state, checks PaintingEnabled(), and calls the first.
