Ya, I'll have to double check that one, but I think changing
the prototypes (args, return values) of existing methods affects ABI,
but perhaps not const.. You'd think it wouldn't matter, as const is
not really a data size thing, it's just a permissions thing. But not
sure.
If for no other reason, macro'ing it out would allow it to
be investigated easily, and concurrently flagged to be part
of the next release.

I'm not expert on this either.
I'm thinking as_window() (and friends) should be more like the
window() prototype (const method, returns non-const pointer)
if for no other reason, just to be consistent.
window() has been around for a looong time, and I don't think
anyone's ever requested const variations, so not sure variations
would be needed..?
