Bug 122048 fixed print preview such that plugins won't cause a crash or hang by
deactivating them altogether. This bug is about reactivating plugins in PP.
The plan is to create an offscreen that the plugin renders into once and then
just display that for PP. That solves widget reparenting issues, freezes
animations and events, plus simulates IE's behavior.
