Dispatcher: avoid multiple cre rerenderings when many settings changed (#9651)

Browse Source 
When a gesture/profile was updating multiple cre settings,
each setting handler would emit UpdatePos which each would
force a re-rendering.
When this might be happening, postpone the rerendering
until all are set.
Needs some bit of refactoring to the events at play:
introduce "DocumentRerendered" event, and use it where
we used "UpdatePos" or "UpdateToc" to mean exactly that.
