iOS: Don't claim that windows with zero width and/or height are exposed
When sending expose events to Qt, Qt will ask us if we're exposed,
and we need to tell it that we're not, so that clients will not try
to makeCurrent on a CA layer that has a zero width and/or height.
Note that this only works because we flush expose events.
