26: * Recalculate window and session sizes.
27: *
28: * Every session has the size of the smallest client it is attached to and
29: * every window the size of the smallest session it is attached to.
30: *
31: * So, when a client is resized or a session attached to or detached from a
32: * client, the window sizes must be recalculated. For each session, find the
33: * smallest client it is attached to, and resize it to that size. Then for
34: * every window, find the smallest session it is attached to, resize it to that
35: * size and clear and redraw every client with it as the current window.
36: *
37: * This is quite inefficient - better/additional data structures are needed
38: * to make it better.
39: *
40: * As a side effect, this function updates the SESSION_UNATTACHED flag. This
41: * flag is necessary to make sure unattached sessions do not limit the size of
42: * windows that are attached both to them and to other (attached) sessions.
