What really should be done (TM) - is that scrollbars should be _removed_ 
from all widgets that have them currently. And then there should
be a generic interface added so that you could drop a
Viewport, a Text widget, a CList, a CTree, a GtkLayout, a
GnomeCanvas... etc. inside a GtkScrolledWindow and
it would work.

(Currently, a GtkScrolledWindow can only contain a GtkViewport)

Probably the way this would work is that any widget that
wanted to be scrollable in this way would create a signal

 "set_adjustments" (GtkAdjustment *hadj, GtkAdjustment *vadj);

and the ScrolledWindow would check for the existance of such
a signal when a child was added to it.
