	Wouldn't extending ggi_visual be more appropriate?  After all, a
window is really just a specially-handled visual.  And as you can attach 
arbitrary metadata to a visual right now, LibGWT could just attach

	...to the visuals it manages as windows and you are all set.

	If you want "window modes", keep them separate from display/buffer
modes.  Have LibGWT handle them internally, IMHO.
