Can you resize a window from javascript-land?

[Tim Cuthbertson <tim gfxmonk net>]

Is it possible to resize a window from gnome-shell javascript code? I
believe I hold onto an object of type "MetaWindow", and I've looked
through the Shell.gir and Meta.gir, but found no relevant methods to
call.

The C type seems to have a check_resize function that sounds useful,
but I don't see any way to access that through javascript world. I'm
still very new to all this, so apologies if I've missed something
obvious. Is this possible, or is window resizing entirely left up to
the C mutter code?

Thanks,
 - Tim.
