Hmmmm. I really, desperately, want to avoid keyboard grabs as much as
possible. But I guess Alt-Tab in a VM is the one usecase which can't
route around this. Out of interest, do you know if that works on
VMWare/VirtualBox/etc on OS X and Windows? If they don't, then we
don't have to either, and we can just make this private to XWayland.
If they do, then I guess we probably need to follow suit as well.

If we do though, I'd prefer to see two protocols: one for native
clients which demands a matching wl_seat serial, and another for
XWayland which doesn't have that restriction.

Note that this is basically just about the concept; I haven't looked
at the exact detail of the wording yet.

Cheers,
Daniel
