Yes, set_invalidated() makes no sense at display() time.

Properties can be functions, right? So a textfield might need to
update itself in every frame without any other accessing that
property. Does the current design deal with this?

What about simply adding an additional step after
movie_root::advance() where each text field explicitely checks it's
associated variable and calls set_invalidated() if necessary?
