How to remove Margin/Padding next to WindowHeaderIcon / WindowHeader

Hi Isomorphic,

I'm looking to achieve the design from "Aim.png".
Please see the Firebug screenshot "Margin_next_to_HeaderIcon.png".

If I change the 2px for "left" and "top" to 0px, I'd get what I what.
Could you introduce those APIs in 4.1p? I can't do it with CSS I assume, as the remainder of width-2-2 (minus additional 2) is used as Header width (here 694px), the window width is 700px, see screenshot.

Is there another way to do this?

Thank you and best regards,
Blama
