I don't see the problem here. A draw widget is a draw widget whether
is in direct graphics or object graphics. The same keywords still
apply and you still interact with it in the same way. The "thingy"
(my own object-oriented terminology, what do you think?) that you
draw into is the only thing that is different and is set by the
GRAPHICS_LEVEL keyword.
