I'm not quite sure what you mean about procedurally generated content, but if you're asking "can you add an infinite number of elements and scroll all of them", yes. The scrolling is based on the content you place inside the scroller.
Unfortunately, right now it does not support scribble - I thought about possibly making a "create_auto_surface" that would allow you to put whatever you'd like in a callback (like scribble), but I haven't gotten that far yet...
