    preview-view: Use the correct height and width when drawing background
    
    We should use the widget's allocated height and width when rendering
    the background. The (0, 0) of the Cairo context coincides with upper
    left corner of the widget, not the clip rectangle.
    
    Not entirely sure why we didn't see any bugs because of this, but
    let's do the right thing.
