We change the behavior slightly from the initial implementation in
5.1. Forcing the use of native child widgets is causing massive
performance issues so instead, we attach the embedded QWindow directly
to the root window. The only exception is QScrollArea and QMdiArea
which still enforces native windows for the entire parent chain
to make clipping and stacking work.
