Only complete sync draw for visible window

Otherwise the sync may be finished too early if the client perform
relayout with View.INVISIBLE (e.g. the activity is stopping).

Besides, window manager service should only consider View.VISIBLE
as real visible.

Also change constant field from commit cf9955ff to reduce conflict.
