Something related I noted some time ago.
I find the smoothed ROIs a bit puzzling. Sure for deforming an ROI they might 
be useful, but is it possible to see what is in and what is not in the ROI? 
Can one "draw" a pixel-accurate ROI this way?

Is there any option to have "thin" ROI edges instead of these thickened 
overlays?
