as an aside, it's possible to write a function that uses only the 
documented interfaces to build a structure in memory that contains all of 
a window's cell-data.

The members of WINDOW are technically undocumented (which is used in the 
NCURSES_OPAQUE feature), but iirc there aren't any "interesting" bits that 
aren't available through the corresponding opaque functions.

Putting the two together as one struct that also works with whatever
curses implementation isn't portable though
