Render: Propagate view updates to draw engines

Currently, draw engines are not notified of view updates if a render
engine is active and was updated. It is unclear why this is the case
currently, but this behavior was part of the initial commit.

This patch propagates view updates regardless if the update was handled
by an active render engine. This is needed by the realtime compositor as
it implements logic for view updates, which currently does not execute
if Cycles is rendering for instance.
