Chrome has expanded their content and toolbar area by one pixel so that the window frame becomes one pixel narrower. The window frame is still substantial enough to be an easy resize target but the window feels lighter and just a bit more refined. I think we should consider this. If we do, we should be careful not to cause the corner bustage that Chrome has where the window controls are positioned to break the roundedness of the top right corner. Screenshots attached.

Looks like a polish candidate. I'll let shorlander call the shots here. :)

I am waiting to see how bug 588764 plays out. I suspect we will have to do this anyway to accommodate the shadow.
