Yes, it' just what I meant. I hadn't the right word for it... ;-) 
'stroke width' is perfect.

Maybe. Anyway, the designer and also the user aren't aware of this 
practice. So I think it's good to explicitate it, 'cause it's very easy 
to accomplish.
I also think that we should refer to the worst situation permised by 
user agent. By now, it's Explorer for Windows at "Very big" text size, 
in the future it may be another one.
