Actually, that is what I meant: the core should be using plain ImgLib2,
and the IJ1 plugin should be a mere wrapper that uses imglib2-ij to wrap
an ImagePlus in an Img and then hands off to the core of the plugin.

That way, you only have to maintain one code base, and it is automatically
prepared for ImageJ2.
