Ojan Vafai c8d918efa9 Make changing your layout manager work.
If your layout manager changes, then you need to setNeedsLayout,
otherwise the next frame doesn't even get scheduled. We already
correctly handle going from not having layout to having one or
vice versa by doing the more drastic reattaching since that
requires changing your actual render class.
