    compositor: Apply texture filter for zooming
    
    Bug: 15392
    
    The texture filter changes based on the zoom value to give best results
    when zooming at higher levels.
    
    As we do not unbind/rebind at each repaint anymore, the texture filter
    would not be updated, hence the chosen filter is ignored.
    
    Make sure we apply the texture filter when zooming.
