textview: Don't leave embedded children behindtextview-children
When scrolling embedded widgets out of view,
they sometimes get left behind because we don't
reallocated them. To avoid that, move _all_ children
out of view in size_allocate, and let the current
child allocation plumbing move the visible ones
back in place.
