Brave man - I think that's how I interpreted it when I wrote the imglib 
ROIs. If you are to count pixels, it's by whole numbers and the 
criterion is whether the integer coordinate falls inside the region of 
interest, not how it's drawn. Area is a different measure and might very 
well be different than pixel count. Unfortunate as it is, maybe the 
visual representation is just illustrative, not normative.
