    treeview: Don't draw a background for the bin window
    
    The bin window's background would have to be drawn in the bin window's
    size and inside the pixel cache draw function to not cause transparency
    issues.
    
    But because it's unnecessary as the view window draws the same
    background, we just skip it.
