------- Additional Comments from Alexey Proskuryakov <ap at webkit.org>
I guess it's OK to add = another null check (there is enough confusion about
when they are needed in this file already). 

It would be much better to find out why anyone would call
notifyPageThatContentAreaWillPaint() when there is no page, and they are not
painting, and fix that instead.
