Some windows have WM_NAME of 0 bytes, so I have to ask for _NET_WM_NAME
Atom, but some windows have it as XCB_ATOM_STRING and most of them have
it as UTF8_STRING, so I'm just reading UTF-8 one.
And ALSO coordinates from xcb_get_geometry are relative to the parent,
so I have to translate them using xcb_translate_coordinates, which would
be fine, except it completely kills my "queue a bunch of requests and
read responses later" paradigm here. Hence, I'm doing it one. by. one.
Fuck this shit.
