I hardly see while it would ? (it is now, but there are a lot of reason behind 
that which I am working on, including and having paintLine in the paintOp 
would help, and while playing with the freehand tool I noticed a lot of 
problems with our call to dirty rect, we are overprotective).

I wasn't suggesting that the dynamic paint op should be the only way to do 
bristles :) (or paintop) or at least not yet (in photoshop, brushes are 
allways dynamic), it's too experimental for that. But I definitively think 
that having a bristles paintop which call other paintop is the right 
solution.
