    compositor: Really avoid painting a screen of zero size
    
    Bug: 15852
    
    Previous attempt to fix a crash with a screensize of 0, which can occur
    without any output connected was incomplete (commit 3925109d) as a
    client might still trigger a repaint by queuing up damages.
    
    Make sure we take this case into account as well.
