Middle of the button, right, that's what my patch does in mouse capturing; the 
rendering is already correct. And this way, the button will never exceed the edges.

I understand your aim for abstraction, but both capturing and rendering are 
bound to the same screen positions, and the related calculations must match; I 
see no way around.

What do you mean by design plan? A skin definition gives the layout, but placing 
  variable elements inside the skin like a potmeter button is finally handled by 
the code, of course regarding the constraints given by the skin definition.
