I fully agree.  We will need to decide how to separate that properly.

Absolutely.  But to my knowledge, the current IJ2 display builds upon
DatasetView which builds upon ARGBScreenImage which builds upon AWT
Image.

https://github.com/imagej/imagej/blob/master/core/data/src/main/java/imagej/data/display/DatasetView.java

Am I missing something else?  If not, that would need separation too,
many alternative DatasetViews to come?

Yes.
