Presumably something like the widget signals would be wanted.  It'd be
a happy side effect if it meant each distinct gtkwindow was a unique
scheme level object.  Good for hashing, comparing, etc.

I'd thought at one stage of proposing an equal? handler for the boxed
types as a similar thing, but ended up doing what I wanted a different
way.

gdkfont has it's own equal function, gdkcolor doesn't need one (on the
pointer value), and gdkcursor seems not unique at the gtk level, so it
was only gdkwindow I was looking at.

I doubt that's to be taken literally, not if anyone is meant to be
looking at the code.  I'm not trying to be critical, just that it'll
be highly advantageous to others interested in the project if you can
better communicate changes you're proposing.
