Indeed I do not know :) As I told you privately, I'm really impressed that 
you succeed in doing that, and I'm impatient to test your new wrapper 
technique by myself :) Let's pray that GE won't patent it :)

I do believe you :)

That's what I thought when I saw the imaging filters for the first time. 
But as you mentioned : "this functionality is slowly creeping into the 
"graphics" pipeline.)", thus I was just wondering...
