* (nicm) Partial resizing support. Still buggy. A C-b S and back sometimes fixes
it when it goes wonky.

* Recalculate window and session sizes.
*
* Every session has the size of the smallest client it is attached to and
* every window the size of the smallest session it is attached to.
*
* So, when a client is resized or a session attached to or detached from a
* client, the window sizes must be recalculated. For each session, find the
* smallest client it is attached to, and resize it to that size. Then for
* every window, find the smallest session it is attached to, resize it to that
* size and clear and redraw every client with it as the current window.
*
* This is quite inefficient - better/additional data structures are needed
* to make it better.
