/*

|
* 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.
|
|
*
|
|
* As a side effect, this function updates the SESSION_UNATTACHED flag. This
|
|
* flag is necessary to make sure unattached sessions do not limit the size of
|
|
* windows that are attached both to them and to other sessions which are
|
|
* attached.
