Thick title bar window in cocoa, similar to iTunes

Question

I've been looking around and I can't find much information on how I would go about creating a window similar to the Mac App Store or iTunes. It has a thicker title bar with buttons ect. as you can see in the image below.

Any help would be much appreciated.

There are some similar questions to this one: Title Bar Buttons and Custom Title Bars.

I think the main workaround is to create your own view to be placed in top of the titlebar as a child of your window's content superview.
