 The original gui.cs was a UI toolkit in a single file and tied to
-curses.  This version tries to be console-agnostic (but currently only
-has a curses backend, go figure) and instead of having a
-container/widget model, only uses Views (which can contain subviews)
-and changes the rendering model to rely on damage regions instead of 
-burderning each view with the details.
