For the "standard" set of windows, DEVICE,WINDOW_STATE=window_state
works, but this seems to apply only to windows 0 to 30, and the Draw_widget
comes out of a pool from 31 or more. I ran across this when trying to make
a window manager which would remember plotting states in different windows,
but never found a good way to handle widget windows. In the end I wrapped
the WSET inside an EXECUTE(), and caught the error (if any) that way. Please
post if some more graceful approach is possible.
