How do you propose to do that?!  Variable elevator sizing requires some idea of
the size of the visible area relative to the view size--the scroll bar has to
have four parameters.  The Control Manager dictates that each control has a
min, a max, and a value--three parameters.

You could make a new control with some hack to get the elevator size into it,
but I don't see how you could retrofit that functionality into CDEF 1.  How
would you get the applications to tell you how big to make the elevator?
