    BoxesMiniGraph: Replace hardcoded colors by theme colors
    
    The BoxesMiniGraph will now invert colors with the theme if needed.
    
    This is a minor visual change while it allows Boxes to adapt to theme
    changes and especially makes themes like the high contrast accessibility
    theme work.
