Jakob,

What is actually happening here is that the first two lines of 
_get_layout() are equivalent to the second method I suggested (that's 
where I got the idea for that method), and the renderer argument is 
never being used. This is good, because the renderer argument would have 
to be a renderer instance, not the string name of a backend.

There is also the caution that the leading underscore means 
_get_layout() is intended for internal mpl use only, and subject to 
change without notice. So, with some future version of mpl, you may need 
to change your code again.
