I don't think that this is equivalent to what I want.  I want there to
be two types of procs: those that know about windows, and those that
don't.  Those that do would be told about window changes, probably
with a signal.  Those that don't would not know that they are on
a windowing system.  Their window would look like a terminal.  When
the user does something like change the size of the window, that would
not change the logical size of the window, just the physical size.

[ by the way, I am assuming a windowing system that keeps track of what
  is obscured by other windows, not one that requires procs to redraw
  their own screens.  Thus, the only window changes that a proc should
  care about are size changes ( and deletions... ) ]

Note that under this scheme I should be able to take vi or rogue, and
run them with no changes at all.
