Ah, you mean report that data back to the tool.

Or even complex loaded -- left blue, right green.

I've had a long discussion about resolution with someone whose name has 
temporarily escaped my mind; the image resolution mockup in the imagesize 
plugin was the result of that. It should actually be quite easy to implement 
-- then 1:1 zoomed image would be as big on screen as on paper (given a 
correct dpi for X11, of course), but you still have a problem with the tablet 
that has a more pixels per square inch than the screen. Or at least, mine 
has, because it's the smallest, cheapest model wacom.
