This class *could* be useful in other cases besides macOS. So perhaps you can move it to share/classes/sun/print ?
I note that macOS printing - unlike the Postscript and GDI cases - doesn't depend on the Banding raster print path.
To use it elsewhere, if there's transparency, we'd need to do something similar there to translate the band to gray - but that should not be too hard, if we need it.
