+ The <code>/set_surface</code> should be set before this is called. That way
+ The right set of strips will be sent in return (though the default is good
+ for most uses) and feedback will start correctly.

+ If the surface is using <code>/strip/list</code>, the surface needs to know
+ if the strips have changed. This would be true if a strip gets moved, created or
+ deleted. When this happens Ardour sends <code>/strip/list</code> to the surfaces
+ that have previously requested a <code>/strip/list</code>. This lets the
+ surface know that its list of strips is no longer valid.
